The ONLY reason I'm interested in one is to STOP a "parasite drain" on my tractor. And the only reason I'd prefer a kill switch in preference to pulling the terminal off, is I've done that so many times the wiring into the terminal is damaged (I'll have to solder the terminal onto the wire).
Nylon spacer means conduct area is very small and this can cause charging, or operating issues. If your having earth type problems on your car / boat, check this first!
I thought you said it goes on negative terminal. Maybe I’m missing something but the red wire going to the device installed usually means you installed it on the positive leg of the circuit.
its not about being triggered. its about safety. these conventions exist for a reason. you or someone else could easily mix them up and cause a short, a fire or destroy your electronics
I bought one yesterday at wallmart for $4.something, torally recomended! to the peoploe that did NOT read the Notes... te Red cable on the Video Its NOT the Positibe he used an extra cable.. thanks for the vid man
@@SteveV74 No, don't connect this to your positive side. Only negative side. You do the positive, and while driving if something touches or interferes with the positive flow, it can burn out your computer boards and other fuses. Turn your engine off, then turn the kill switch.
....The Mistake stims from Two factors .....Being Color Blind OR.... A Failure to Read Directions! NEVER EVER PUT A BATTERY CUT OFF SWITCH ON A .....POSITIVE BATTERY TERMINAL !!
Why to ground side ? Is the device not Amp rated ? For someone unable to locate an existing short drawing down the battery and the vehicle somehow gets grounded the battery can continue to drain. Example a farmer with tractor pulling implements that are Iron connected to tractor and no tires. In this case the negative connection would not help, you would need to find one with a positive disconnect.
Exactly the situation I have. Theoretically a negative disconnect still works, as even with a "live" positive there's no connection back to the battery for current to flow (you can connect the positive direct to ground - nothing happens because there's no "circuit"). However, this "kill" switch clearly still allows leakage, so it isn't going to work on my tractor! (Easy enough to just pull the terminal off, but I've done it so many times I've damaged the wiring and will have to solder it together).
The safety protocol in mechanics is that you always connect the negative terminal last and you always disconnect the negative terminal first. Following that procedure ensures that you do not accidentally short a hot wire against the car body or frame and make some sparks.
The volts don't go down to zero. It seems like some electricity is still running through system. I have this product for my rv. I loosened and tightened the disconnect screw and it still read 12+ volts in my RV... as though it didn't fully disconnect anything. Ideas?
The plastic separating the top and bottom metal is very thin and if the plastic is not glued to the metal parts the whole assembly is loose and prone to still short even when you unscrew it. The one I have wasn't glued together and was loose, so I used expoxy resin glue between the plastic and the metal parts to make a firm bond so when you unscrew it, the whole unit remains tort. Tested with multimeter and it shows 0.000 continuity
Bella C just take the negative side off of the battery. They sell those little battery terminal wrenches at Walmart in the battery section. That’s what I do on my van camper. The problem is everyone wants everything too convenient nowadays. It is called laziness.
Without a complete circuit it's not possible for something to be draining the battery. It's much more likely the battery is bad. Even a new battery could have a defect. There's one possibility. A low power circuit may be being created if when the hood is closed somehow it is touching both terminals. Look for marks on your hood. You can also buy a piece of rubber and glue it to the underside of the hood above the battery.
I like the concept but it's still showing current is being drawn from the battery. What's the use of it if you're wanting to use it to stop your battery from getting drained? A buddy of mine is having problems with his lawn mower battery not staying charged and this wouldn't fix it.
What you are probably seeing is a parasitic drain feeding back through the wire from one of his on-board components. A lawnmower would not have that. Before investing in one, disconnect his negative terminal and use a voltmeter to see if there is a drain on his battery through the wiring harness. Then if there is, you can follow the leak down the wiring harness, disconnecting each component as you go to find out which component is bleeding off current and draining the battery. Very likely it is the magneto, which is probably located under the flywheel.
@@Matthew_Loutner thank you for being smarter than I am. Personally I was lost and couldn't understand it and then when I was reading what you were saying and I started thinking, maybe it's a headlight because it is equipped with two headlights. Then you said there's a magneto under the flywheel, I didn't have a stinking clue of that. It was definitely be on my pay grade. Could that magneto be the reason that it backfires when turning it off? I understand if you don't know but because I can tell you're smarter than I am, I have to ask.
@@DonaldAJr Backfiring when you shut it off is called afterfire. It is unburnt fuel igniting inside the muffler and exploding. It can be due to number of causes from carburetor adjustment to running too hot to a fouled sparkplug not burning all of the gas. Try letting it idle for 30 to 60 seconds before turning it off and see if it still does it.
hello please tell me for how long can i have my car without batteries is there a limit ??? if a car dating back to 2010 is left for several months, will I have problems with the brains and the alarm ??? please say thank you
I see by indication of your voltmeter that the amperage did not go to zero (when knob turned CCW), indicating there was still some slight drain on the battery occurring. Do you know why? Is it because the disconnect itself is less than perfect and is still allowing a slight connection? Or....?
The threads of the knob are still in contact with the terminal lug. You should completely separate the two pieces for a total disconnect. It's not hard to re-screw it since it's a big green thumb screw and don't need any tools.
FuzzballToday yes but it doesn’t do 100% disconnect. As far as tools it just takes a battery wrench. Walmart $4.00. I put mine on a keychain and hang it on the turn signal. But I understand with this you don’t need the wrench.
I keep an unregulated 500 Mah 24V battery charger on my solar battery bank of 16 deep cycle100AH batteries. Lead acid batteries like a little ripple in the DC to keep the sulfation off the plates. I also keep my batteries (no matter what the use) CLEAN to keep conductive dust off the tops of the batteries causing a high impedance short from forming and slowly draining the battery over time.
@@luisbelloso7282 I just ordered a side post isolator and my battery is in the trunk (2003 Saturn Ion). I believe I have a parasitic draw, but I cannot even figure out how to find it. So, I figure if I shut down the battery it will not draw the battery down overnight.
When you use a disconnect switch such as this, won't you at the same time erase all memory and such from the radio etc? Forgive me if it's a stupid question, but I'd still like to know.
Usually yes, though, there tends to be devices that you can plug into the cigarette lighter socket that provides just enough power to keep things from losing memory, but makes it safe to work on the vehicle. Still a bad idea to use those if you know something will be shorted for awhile under the hood.
You can use them for 72 volts. What you have to check is the amperage rating on the box. Mine is rated for 125 amp continuous and 500 amp surge. The surge is for when you are applying the starter.
one item he didnt mention...actually two.. one.. the directions on the same iten at walmart says..

Sure, if you want to confuse yourself, and connect the jumper cables backwards and ruin the computer components of your car. Don't change anything, use the shutoff on the NEGATIVE pole of the battery - never, ever on the positive pole.
@@carsandstuffchannel1252 would this work if I hooked up a heavy jumper cables, to battery and put the switch in car, and run off the other side, back to the cars ground, to use as a battery kill switch cause something is draining the battery, and such a hasle having to open hood every time to connect battery terminal?

I think you should clean the corrosion off of your wire connection. Corrosion offers resistance which lowers the available current and voltage. 😎
i bought this today as a way to mitigate a parasitic battery, under 10 bucks installed in ten minutes, works great.
I have the same problem, so u had to problem with battery drainage after this.
@@JAlves88 no, i fixed the problem with this device!
It doesn't eliminate all the current going thru the battery. Just enough to keep the vehicle from starting. Will not stop a parasite drain.
