Fantastic. You're the only person I found on TH-cam that showed me in clear terns how to find an earthing point. I had thought the side of the van but wasn't 100%. So found continuity on it and happy days 😁. Thanks
I'm an avid TH-cam watcher and lets face it, there is some really great videos on the web, but also, there are lots of useless ones as well. These videos made by Combe Valley are all excellent. Well filmed, well explained and very informative. Thank you so much.
Great video, thank you. PS thr “star” shaped tools are called torx 😉
You are the first person to use dirty tools and I'm very proud of you for that. Most videos the tools look brand new with no marks or dirt on them. Great video and I just became a subscriber
I really can't get over how good these video's are, I'm learning so much !!
Alun I have only just found Lee and your right his videos are top notch. So much so I will get rid of the others I have book marked,
Great video. Just on the point about your spanner arcing to the car body ... always disconnect the negative first and this will never be a problem.
Fitted my split charge kit this morning exactly as you showed in your video - all went perfectly, not in the least bit scary or stressful. Thank you!
Thanks lads, I just brought one of these to do.
Lee your videos are spot on am just onto sorting out a t4 for summer n all your vids are just what am after. spot on, clear, straitfoward👍👍👍👍👍😎
Thanks, very interesting. Just one comment, I was taught as a earth moving plant mechanic to always disconnect the negative terminal first. The plant we work on is mostly 24 volt. If you accidentally touch the tool from the positive you're in for a serious burn. Therefore it is safest to first disconnect the negative terminal. Sorry, not criticizing just trying to be of help.
Agreed, I lost my head a little during filming!
Loved the trick about removing the Plenum cover :-) My T6 Caravelle has a sunroof and discovered the grommet was used as the sun roof drain. There is another 20mm grommet on the passenger side just above the wheel arch.
Cheers Lee 👍🏼 I’ve already started converting my T5.1 after watching your videos 🚐#vanlife
Great video, it has really helped me to do mine! Please do a video showing how you’d advise to mount a battery under the drivers seat!
Great video very professional
Excellent video thanks for putting such high quality content out there. Just a quick question: if you could remove the passenger seats where would you have run the cable?
Brilliant videos! I managed the upgrade my T3 head lights thanks to your tutorial video. I am struggling a bit with my 12 volt circuits. Can you do a video explaining how to wire 2 eisure batteries up and add a volt meter?! Thanks 👍
Honest and useful.
Loving your videos. I want to fit the battery under drivers seat in my T5 but not sure how’s best to do it, are you planning a video on that at all?
Great install video, very informative, also very nice hats, love the logo design in burgundy looks very smart 👍
Really good explainer. I bought this kit years ago, it was shocking (heh) quality, same for the fuse box. BlueSea systems fusebox that I did get is great. Battery terminal clamps are really cheap and nasty too. In any future vans I'll likely just buy the cable on it's own. Only good bit was the VSR. Another thing I'd like do is take the positive feed from the van's fuse (Fuse holder A) under the battery. Looked to be a few spare ways, takes 100A+ fuses and keeps the extra cable out of the way.
I love your videos!!! thank you so much!! however when I follow the link for the Split relay Rayne Automotives say this item is no longer available, so are there any more recommendations or product? many thanks
Really informative and helpful, thank yiu. How would this system work with a vehicle that has two batteries?
Thank you. First video of how to for split charger. Wish the lighting was better especially when attaching to both batteries
Awesome videos. Looking at adding solar panel, antenna, wifi so I can work remotely. Any tips etc. would be awesome.
I am looking for more information on multiple power sources in combination (this plus solar plus shore), on batteries in parallel, and something a little more comprehensive about power distribution than just the simple LED lights.
I checked for, and did not find, a relevant playlist.
Thanks for your videos so far.
Hi, a really useful video. can you please supply the details from where the wiring kit was purchased. Cheers
Great video ✌️👏👏
Flipping brilliant 👌
Hi, Great vid! Helped me a lot!
If my leisure battery is fully charged but when driving the voltage sense relay still kicks in, is this a problem for overcharging and should I disconnect the leisure battery? Or is this normal?
Thanks mate
Great video as usual, but I can't find the link for smart spltter, and what shall I use to charge my LFP leasure battery? TIA
Hi mate. Is the older sprinter 16 plate, a smart alternator do you know. Was looking at a sterling b2b. But pricey and in fact.... would it harmful to use something like that if it isn’t a smart alternator.
Thanks
When sealing wiring grommets I find a glue gun is great when using flexible glue sticks plus it's neat and fast
Your videos are ace and will defo help me with my conversion. I’d still probably bring it to you for the electrics though 😅 Got to have the pros sort that one for me.
Thanks :)
Great video ! I have a couple of questions :) where could I buy this kit, in the link is not longer available. How can I connect a fridge to the second battery? thanks !
Hi, I have noticed that my conversion does not have a fuse breaker connected under the bonnet feeding from the van battery, I have purchased a fuse breaker with 100amp fuses and lugs.
Will I need to disconnect the leisure battery before disconnecting the live cable from the van battery ?
There is one feeding from the split charger to the leisure battery.
Your advice would be much appreciated and you videos are excellent for great advice!
Hi , thank you so much. What will happen if i connect directly into my leisure battery + to my car main battery + to charge my leisure battery. I'm thinking of putting manual cut off switch to control charging while driving and using leisure alone while camping. Please kindly teach me.
So useful thanks man!
My leisure battery bank will be at the n/s rear of the van under a bench seat... can I route in from the engine bulkhead, behind the glovebox and up the a pillar?!
Yes, absolutely, there is plenty of room. However, do not disregard routing on the floor.
Hi there any advice on taking the mini bus seat rails out on a t4
Do you have a video on where to route the cable to the drivers seat whilst the seats have been removed?
When mounting the battery under either passenger or driver's seat, where do you put the split charge relay switch and the fuse panel... Do you simply mount those to say the seat base? Thanks
Brilliant video Lee, could you please do a video on how to wire up 12v fuseboxes, lights and switches?
Yes we shall. One step at a time!
Combe Valley Campers Cheers. Would love to see an update on your T25 too dude
Can’t wait to see you guys get this vid done, will complete my van conversion
I know you need an inline fuse close to the positive terminal on the campervan battery... but do you need an inline fuse close to the relay as well? One inline fuse only? Or a second near the relay? thanks
Does the t5.1 have a smart alternator ? also what's the best way to fit the leisure battery under the seat I have a shuttle with black carpet so I have electrics under the passenger seat so will need to route cable to drivers seat is the carpet a pain to remove ? And do I need to bolt battery to van under the seat and earth it to the seat frame ?
Hi Lee Thank you for another great video,you spoke about a smart alternator.Would my VW T5 Bus (Transporter) 2009 have this fitted.
Likely not, but if you head to www.rayneautomotive.co.uk there is a blog post explaining how to test for one
If you want to wire the battery under the passenger seat can the wire go under the bottom of the seat and up where the other cables come through or would you put a hole in the metal work of the seat with a gromit? Also on a T5, thanks.
Just brought this split charge kit will it work on a smart alternator
Is it OK to run the cable, within a sheath, underneath the vehicle to the rear where I intend situating the leisure battery?
Another helpful video with tips I've not seen elsewhere - thanks. I'm left wondering how you would have routed the cable if you had had access to the passenger seat base. Can you explain?
One thing I haven't got my head around is wiring the neutral circuit in 12 volt system, both leisure battery from main battery, and circuits within the van.
If you switch the negative on the relay then will it disconnects the charge when running ?
Rayne automotive or BusBoy has had many issues .
Used to omit the fuse of the LB end of the SC kit and have a 1.5m run to the distribution fuse box. I removed one from a Mazda Bongo about 18 months ago, as it shorted behind the dash end panel and melted the loom back to the battery, That distribution fuse box still has no main fuse close to the battery. When will James (Busboy) learn?
Can you fit a smart relay to any van or does it have to be a newer type van
I fitted one of these and it doesn't seem to be charging my leisure battery, any ideas , 58 plate transit , thx
Would it be easy to connect 2 batteries up to 1 split charge? And could you give an estimate on how long one battery would last, say for example if I worked for 8 hours on a laptop. Would it last days or hours?
Is there a particular reason the relay goes at the leisure battery end, can it go at the vehicle battery end?
hi will this also fit a ford transit custom 2015 ?
Could this system charge an LiFePo4 battery?
What size/thickness of wire do you use for a split charge relay (140 amp)?
This is a great video. Would you be interested in fitting a split charge system in my L200 truck please? I’m thinking of putting a second battery in the truck bed to power a fridge etc. also thinking of installing a solar panel on the truck canopy roof. Thank you.
Hi Mark. Please feel free to email info@combevalleycampers.com and we can provide an estimation
Smashing
Hi could you take the wiring across the bulkhead and through the grommet on the drivers side into the seatbox cheers Simon
You can route the wiring in whichever or way suits best for you and your build. This is a suggested method :)
Hi Lee, great videos and love your style. You could not remove the seat on this van, if you could, how would you route the cable please? Thanks,
I would have lifted the mat, and followed the factory cable route on the cab floor. I would have then brought the lead out under the driver seat
@@CombeValleyCampers Perfect, thanks Lee. As I am lifting the cab floor, are replacements available as it is pretty tired and grotty? Thanks,
@@tomjoyce7302 yup,we have a video on the t5 replacement carpet available from heritage. Makes a world of difference and fits on top of your rubber mat
I don’t seem to be getting charge the power is at the cable but not charging battery.
The only difference is I wired the leisure batt earth to chassis and the earth from relay to chassis as it doesn’t turn the relay on if I wire the small earth wire from relay to leisure battery. It cuts the relay in as it should but it’s not charging at all ? 😩
Hi Lee, I have a 2004 Abbey Impression 500 Caravan. My Main Isolator is an ESM2004. I have always been confused as to where the Car / Van rocker switch should be positioned. I think I may have been doing it wrong all these years. We have always used sites that had electric hook up and the rocker switch has been in the central position, which was advice from many of our caravan friends who do similar. However, we have always needed to have the battery charger on to make everything work. I am just about to have a mover fitted which has brought up the whole battery question. Please can you tell me where the switch should be and if the charger should be on permanently. I seem to get mixed opinions elsewhere and am encouraged by your no-nonsense easy to understand explanations. Thanks
did you find out correct way please
HAHAHA I have a nice wet driveway AND im fitting my batteries under the van - this will be great fun! 7:35 as a qualified engineer/ electrician I ALWAYS take the earth off FIRST! I HAVE touched a spanner on the body removing live and Its NOT FUN - I'VE DONE IT!! My old dad was ex REME and he taught me - about the Earth.... REMOVE FIRST - REPLACE LAST. Just to be safe. Not trying to be 'clever' rather dont want someone to get a nasty shock 👍 CRACKING VIDEO 'GROMMIT' 🤣😂👏👏👏 Running my cables under the van in 'Copex' might be easier for me with underslung battery box.
Can I use my leisure battery to power things in the van whilst also driving and charging off an alternator? Should I turn off my van electrics whilst charging or can I charge and discharge at the same time?
You can keep everything on with no worries. It's the same as turning your headlights on when your driving. Your alternator is charging the car battery whilst you're driving too :)
IG and FB links aren't working (at least for me) Perfect timing for the video too, due to do this job in a week or two
Thanks for the heads up. Ive edited the description now and they should be working fine :)
I may have missed the video but if you have the passengers seat removed what is the path you take from the firewall to the battery? My passenger seat is a twin seat that rotates FYI. Great videos btw, currently building mine using your guides.
If the mat is up, and you've full access, I like to follow the route of the factory wiring as its within the troughs of the cab floor prssings
@@CombeValleyCampers Thanks, sounds good. Is there also a better way of tidying the existing factory looms that used to be located in the oem twin seat base? Because I’m using a swivel base the advise was to just tuck them under the kombi cab matting, but the plugs are fairly chunky. Currently they a tucked in a dip in the flooring.
You keep referring to earth point. A vehicle with rubber tires can't have an 'earth' it's a negative terminal. The van chassis can be used (and is used) as a negative return to the battery. You have positive and negative, no earth. Love the channel
Hi guys at coombe valley, i have purchased and fitted a towbar for a t5 with no electrics. Towbar brilliant. But its to transport bikes so when bikes loaded, reg of van and a tail light covered. So need electrics for a light and reg bar. Does your electrical supplier do an easy fit kit? Look forward to your response. Luv the vids.. and yes im a subscriber.
Hi Mark, thanks for your comment and support. Modern Van's such as T5s and T6s have Canbus electrics system which is something I have little knowledge of but i do know that towbar electrics may affect them. Please seek the advice of a specialist towbar fitter in this case
@@CombeValleyCampers ok thanx guys
You used 100amp in line fuses between batteries and vsr. How did you figure out the amp rating for these?
The kit came with the fuses from Rayne Automotive
Where can I earth my leisure battery? It’s under the drivers seat
What's that nice thick white insulation material you have in the walls?
That is thermo fleece. Take a look at the products page at www.combevalleycampers.com and you will find it under insulation and sound deadening.
Sure you know your job, but it is safer to remove the earth from the battery 1st, then remove the live. Dodgy practice to leave the earth connected.
Thank you for highlighting this. You are correct
@@CombeValleyCampers I didn't want to disrespect your efforts, and your vids are really informative. Just don't want any one to accidentally earth out that live terminal with a screwdriver or something. Had a mate short his wedding ring on one, can you imagine? Great work sir.
Thank you sir. I appreciate it.
@@CombeValleyCampers I would have thought you only need remove the earth. If you remove the earth, there is no risk of shorts from mishandled tools, once it's disconnected there is no longer any risk of shorts.
@@brokenrat2176 I have head of that happening. Your mate should not have been wearing that (or any) ring, or any metal object capable of receiving 12V such as a gold chain around the neck.
What dimensions does the battery need to be to fit inder the single seat with a tray
I dont have the dimensions to hand but a quick google search for t5 low height leisure battery should provide results
Whats a rough cost of fitting this?
So if I was hooking up my solar panel to my 2 leisure batteries, and then connecting my split charge relay to both my leisure and van(transit) battery, connect up to the leisure(positive & negative), and then remove the fuse in my split charge relay before connecting to the positive and negative on my transit battery?
Ive read this three times and im still not up to speed with what you mean. Sorry @amacmedia
Combe Valley Campers apologies, basically I was just double checking that you disconnect the negative then positive from the main van battery first, then remove the fuse from the split charge relay before connecting to the van battery? Then reconnect positive and negative to van battery?
Probably a stupid question! but if i have a van with a separate leisure battery charged via a split-charge system and i inadvertantly leave something switched on that drains my vehicles battery does that also drain the leisure battery? also if the leisure battery were to remain fully charged at the expense of my vehicles battery could i utilise the power of the leisure battery to start my vehicle somehow?
The Voltage Sensor Relay(VSR) will disconnect the Vehicle and Leisure battery when the voltage from the alternator falls below about 12.8v, so neither can drain the other with the engine stopped. If you wanted to link them to boost the vehicle battery, you would need a separate circuit with a manual isolator switch to bypass the VSR which will be doing its job by keeping them seperate when one is at low charge. Hope this helps
How do you secure the battery under the seat?
There are a manner of methods used. We make a steel bracket to hold it down but i believe modified seat bases are now commercially available
I spent all afternoon installing my spliy charge system. It then didn't work. My kit is from Rayne. Everything I've done matches what your video shows. The only thing I didn't do was connect the main black earth lead to chassis or seat bolt. I thought I could check incoming charge without earthing?
Please connect the earth from the split charge, and also check the fuse from the battery feed cable
Can I fit a solar panel and a split charger to charge same battery ?
Yes indeed
spooky .. i was just watching the video where you had the 2 batteries & VSR/ SCR laid out on a table
oh, and love the MCM chopped fingers flag in background
MCM = my inspiration
Ummm, why is the split charge relay not as near as possible to the starter battery? Why the use of black cable instead of red?
Will that work for a vw t5.1
Yes
Hi Guys. With a split charge relay what is stopping you overcharging the leisure battery?
The voltage regulator in the vehicles alternator. It works the same when your vehicle battery is charging
Where do you get your parts from I couldnt understand the name of the company
Www.rayneautomotive.co.uk
Is there much difference in this process with a van that has a smart alternator?
There are slight differences and we will feature these in an up and coming video. Leigh
@@CombeValleyCampers thanks for the reply, looking forward to the video! I've just bought a 2016 vivaro and can't wait to start the conversation. Your videos are great and delivered brilliantly 😀
Having watched a lot of your videos, you didn’t have to state that haven’t done anything else to the vehicle! I can definitely tell you didn’t do the carpet lining 😬😂
Looks like the wiring kit is no longer available on the website 🤷♂️
When are the hats back in stock ?
Hi. We've been told since restrictions have been lifted there is a three week back log. Keep your eyes peeled, as soon as we have them, you will :)
When you disconnect the battery, if you take the negative off first, then the dangers of your spanner touching the metal of the body is less present
Came to the comments just to say this 😂
you disconnect the negative terminal first. voila, no spark :o
boils starter battery water
What do you do if it doesn’t turn off when the engine is off? 🤔
They are a 'normally open' switch, so if they do break they break open and charge will not transfer
@@CombeValleyCampers Literally just installed it..main battery charge dropped below 11v and the VSR was still on. hmmm
What would you recommend?
thanks for the reply btw :)
@@skisunshine I would disconnect the unit from both batteries and check all connections are correct. It may be a faulty unit indeed. I would enquire with the company you purchased it from
Do you not sell these kits anymore?
Head to www.rayneautomotive.co.uk and fill out their contact form they will be very happy to assist. Leigh
@@CombeValleyCampers thanks bud I will do that now
im pretty sure those are 1/4 inch, 3/8 inch and 1/2 inch drive ratchets, not 1/4, 1/2 and 3/4. 3/4 would be overkill for anything electrical related or removing seats etc.
They are TORX bits ! your viewers will get some funny looks when they ask for "star shaped thingy"
Sometimes you just cant thinknof the right terminology! Can you tell we dont script it!
Oh yes! Although the tv maxim still works - "Engage brain before operating mouth" !! Good vids though ta.
Torx 30
Discontect negative first.never postative first.!!
I think i know what you're trying to type sir, and yes, i agree.
I don't understand with all these kits, why such a heavy duty charging cable. If you are just charging the leisure battery and NOT using it to start the engine you only need cable the same size as the vehicle manufacturer uses from the alternator to original battery, they don't use a cable this size because you don't need to.
Disconnect the Negative terminal first not the positive 🙄 and remove the battery…
