Great video Thanks for explaining this to me. I'm having a problem with the air pump for the air ride. And they said to check the ground. So now I know where to look for them. And I can make sure it was installed right. Thanks again
Very helpful...but..HD dielectric grease?
Power (+) & Ground (-), as basic as you can get. Thanks for the explanation of ‘clean ground’.
Thanks so much for spotlighting a Shovelhead. I will be checking mine soon.
Great info as always, a well grounded source of info. Thanks again Doc
Possibly the best value vid you have ever done mate.....such an important easy to do maintenance tip ...great job
Thanks so much Doc I always like the visual to help me mentally connect with where things are on my bikes. Schematics are great but don't show you physically where they are.
Another great video, thank you!
Still chasing that electrical problem on my Road King...So far 30 hours spent going thru the schematics and ohming out circuits and still cannot get to the bottom of the accessory fuse blowing out on start up only. I cannot wait until I find out what the problem is and fix it but I will make sure that I write something for everyone who follows this channel just in case they run across this problem and it has them stumped....So far Im still have not found the problem....Stumped for now in Florida...
Thank you so much. You have taught me a lot over the years I ride a 2016 Harley Davidson Roadster Sportster and absolutely love it if and when you have time put a Sportster lineup in your show as I said you have taught me a lot and would love to learn more be blessed be safe ride safe
Nice shovel .thanks for the video i always learn something from every video
Thanks Doc great advice. Love that sidecar behind you in the video.
I own a shovelhead you need to use loctite on the battery Cables because the battery box is mounted to rubber isolators Also very important to rout the negative cable properly. I have a twin cam also but when riding the shovel I always carry a 10 mm wrench because I had the cables come loose numerous times
Always accurate and relevant. This time of year a lot of our northern brothers are taking their ships out of mothballs. Maybe the off season was the time to add accessories. The “second” ground was mysterious to me before now. Thanks for the great info!
94 harley Davidson 1340 fxr good starter low output when trying to start maybe wiring grind
Thanks Doc. Great information. I always look forward to your videos.
Good tips Doc, thx, Happy New Year.
I'd like to add the importance of the second ground cable between the engine and the frame on the rubber mount bikes... If that fails, the starter power will take the next easiest path to ground... often you find the clutch cable smoking and seized up because the plastic liner melted.
Great Information, Thanks DOC!
Thanks that’s I have a 2014 street glide l need to check them
Thank you for the great information. Keep them coming.
Great video. fixed my problem after cleaning all the ground connections on my 05 Claasic.
Thanks for sharing your success....Doc
Thanks as always Doc!!
That ground cable looks really thin for such big bike..
That is great info thanks alot.
Great advice as always!!
Very good info!
Excellent video on the 2 grounds ( is it common knowledge there are 2 grounds on later bikes ? ) will add this snippet to my di-electric grease schedule. 👍
Another OUTSTANDING vlog
Very good info 👍
Awesome video Doc👍
Thanks Doc!
Good explication! Nice shovelhead, but it's not a early shovel. Hope to see more about shovelheads and panheads on your videos one day😎.
Cheers from France !

Great info Doc! Cleaned mine on my 18 Roadglide Ulta today. With all the electronics, this is more import than ever. Used a dremel with a stainless brush head to reach in and GENTLY polish up the ground studs,.
Love the shovel
Question. Why does my 2007 Harley Davidson Softail Custom not have a ground on the starter? And when I go to start, with new starter, it half cranks then click click click?
The starter motor of course is attached to motor, motor attached to frame, battery ground attached to frame. You CAN add a ground lead to one of the mounting bolts. Now the click click click….how old is your aftermarket battery? Have it tested. Sounds like your CCA are failing under pressure…..Doc
Great video Boss
Prospect Spider
Thanks!
That wiring harness is crazy!
thanks for infor
What is the deal with the spring under the seat?
More great info Doc! So you guys actually service Shovelheads? Wow...I had to go elsewhere to an Indie years ago to even get service on my Evo.
Yes, we service any Harley-Davidson motorcycle that we have the tools and parts for (even Buells)
That’s some serious electrical spaghetti on that 2019 Harley! Seems like you need to be a professional certified electrician to own a Harley nowadays. Overkill with the electronic stuff on the new bikes.
Good show
Hey doc
Question...I have an 2018 cvo road glide custom
All o a sudden the starter quit dash lights good when I hit the ign switch
Click everything went dark and would come back on
Tested battery and
Relay
Replaced battery same issue
So solenoid would be likely
Went to remove starter and bolts were very loose
Likely just a bad ground??
Good diagnosis 👍…..Doc
Excellent video, Doc!
Thank you…..Doc
doc i got a 21 rgs did a bar swap now cluster dont work either does fuel or voltage.any ideas fuses in fuse box are good everything else works im stumped this bike dont even have 100 miles on it
connectors look a lot the same. check color wire going in and out. Sounds as if you have wires crossed...Doc
@@LowCountryHarleyDavidson only 2 out of the 4 plugs are the same and if i swap them i have nothing on controls so i know they are right the other 2 plugs are diff sizes im pretty sure the prob is not in the bars
I took the battery out of my 2008 FLSTC.
I was down 7 months with a surgery and recovery.
I forgot whether the second ground wire, the scrawny one,
goes with the regular ground or onto the positive terminal.
Doc or anyone? Ty.
Mark nothing should go from negative to positive. If you are describing the battery tender connection, red terminal goes to the positive +, and the black terminal goes to the negative side of the battery. Thanks ~ Doc
Doc! When I touch the front or rear break....?
My "security light" comes on.
This is a 2019 FLHR 107 Road King. M8 Motor.
I will pull the Battery and look at those other grounds too.
Any thoughts? The Ciro Can Bus Decoder is making all the LED's work fine.
My thoughts include what looks like security is really the BCM telling you a brake light is not functioning the way it should🤷♂️….Doc
@LowCountryHarleyDavidson All brake LED lights working. Flashers and blinkers. Yes it is BCM. I'm going to check secondary ground behind battery box on frame
Good-Stuff .
Doc, do you ever experience an m8 softail starter with a bad ground? I’m having a hard to start cranking issue that seems like a weak battery, but it’s not.
Usually it has to do with the positive side. So dang hard to work with….Doc
@@LowCountryHarleyDavidson thanks. I already cleaned all of the positive cable contact points (battery and starter) and torqued everything back down, no change. It’s intermittent and not sure of the specific conditions to replicate it.
those were the days.
cool
Thanks DOC!!! ➖ 👍🏻 🏍
Let me blow you'all minds.... Ready?.... The electric DC current of any battery you had ever seen ACTUALLY moves from the NEGATIVE side to the Positive side when the circuit is complete.... ANNNDDDD a battery NEVER gets discharged, NEVER..... What u call "discharged" "dead" is in reality a battery that is balanced, meaning the positive and negative side of the battery have equal amount of electrones (equal potential, equal Voltage) ...... !BOOMMMMM!
Could this possibly be why my headlight had gone dim?
Yes it is a reason…..Doc
👏👏👏👏👍🏼
2012 fatboy lo., stalling when I pull clutch to roll up to a stop sign. Diagnostics is telling me " Bank angle sensor, short to ground " ....where is the bank angle sensor?
It is part of the BCM, Body Control Module
@@LowCountryHarleyDavidson ok , do you think it's a simple as a loose ground wire , or is that just something its saying because the BCM is faulty ? ......and THANK YOU !!
Does that rusted fender come with that model!😆➕➖➕➖➕➖
Why would my bike 1995 Road King over charge the battery
Battery too old . Regulator failure. Stator grounding. Connections loose. Thanks ~ Doc
I hate any electrical work.
It’s easy when you take the time to learn. Harley Davidson has a service manual just for electrical troubleshooting. It shows you the color of the wire. It’s place in a connector. Where and how the connector looks. How to assemble/disassemble it….if you can read and comprehend. It should be a walk in the park. It has wiring diagrams…. Don’t get me wrong. It can be intimidating but even a legend helps read their schematics. I say you pick up a book. Skim through it and you’ll be surprised how easy it is. I’m self taught. I’m always learning. But just today I learned how to read their schematics. It’s awesome! I can troubleshoot my bike w out having to take it to a shop. It might take me time. But that time will build experience. I don’t do it daily but sooner than later I’ll be more comfortable w it. There are still some things only the dealer can do. Like flash your radio to allow amplifiers to transmit sound to your speakers…. It’s proprietary software not for consumer use. But give it a shot. Search TH-cam for help. I’m here daily just for that. What he’s describing is clean ground and dirty ground. Clean ground is part of the cab bus system. Dirty ground is for your starter…. I just learned that today while going over the book
Follow this guy. He’s good!

Otherwise. South Main Street auto repairs. He’s an automotive electrical genius!
Can anyone help me find electrical connector #31 on 2003 Harley Davidson Heritage Class FLSTC. I have a wiring issue with the Left front running light. Signal works fine. I have the Manual but can't seem to locate Connector #31
In your manual, at the back in the Appendix, page B-20 Softtail Connector Locations......#31 under fuel tank.....Doc
Reminds me of my first grade teacher...or is it me I’m dumber?
Once again no information on side mounted batterys. All this guy offers is basic maintenance information everyone should already know. Not all Harley batteries are under the seat guys!
Anthony not everyone is as advanced as you. Thankyou for sharing your vast knowledge….Doc
Thanks!
