CJ7 Battery cutoff switch.

I recently installed all new wiring for my headlights, turn signals, flashers, brake lights, and parking lights. I also installed a new speedometer. I finally got ALL my lights working correctly. Now, my battery dies overnight. So my "quick-fix" idea would be a battery kill switch, until I decide to start tracing wires that may be causing the issue. Has anyone installed a kill switch??? If so, where did you locate it, on the battery or inside around the dash somewhere (for easy access)??? And what is a good switch to use? I know I probably want a heavy duty one. Any help/thoughts would be appreciate.

How about just pulling the positive battery cable until you can find the problem?

That seems like an easier solution than wiring a kill switch to me.

Eventually I'm going to find the issue. This is just a possible temporary fix.

I installed a knife switch on one of my trucks. You could install one of these and just leave it there permanently. Easier on the battery terminal and cable that the constant on and off

Thanks. I was thinking about going that route also. I guess that would be plan B. My first plan was to wire a kill switch somewhere on the dash for easy access.

If your bound on installing a switch (patience is a virtue, better to find the problem than rig around it and cause a fire), it will have to be between the battery and the draw. This means either the POS battery cable or the main power lead off the solenoid. both are under the hood.

If you splice the main battery cable, insure you use a switch that will take the amps during cranking.

This was my thought as well.

There's obviously a fairly large parasitic draw on the battery to drain it in one night. I wouldn't be comfortable running my rig in that condition.

You should find the problem and fix it asap, IMO.

X2. By the time you wired in that style switch you could have pulled fuses (one at a time) to determine what circuit is causing the draw.

Thanks guys. I'm going to try and find the source of the load tonight. The more I think about it, the more I want to fix it. All seems well until I plugged in my new speedometer...I'm guessing this might be the source, or a good place to start anyhow.

i'd go ahead and install a disconnect switch anyway. tuck it away out of site just in case someone decides they would like to steal it from you.
good luck finding the power drain.

If I just left a note on the seat, explaining all the electrical issues, no one would want to steal it haha.

My CJ doesn't leak oil, it marks its territory.

Not for the problem you mention but just due to how easy they are to hot-wire these old Jeeps in the first place I have thought about hiding one of these somewhere on it.

I have one of the Dual Battery models on my boat and used both the single and dual battery versions on Offroad rigs before. You can key models that need keys or models that don't but I liked the keyed models because you can not only turn off the battery's, select one battery or the other or both, and they are keyed and if you remove the key it locks it in whatever position you have it in;

Hey thanks. I'll most likely do something like this, but first I think i'll try and find the source of the load.

200 amp constant duty relay and a barrel key in on the dash. take the battery cable off the starter relay and no power will go to the cab put the battery cable on one side of the new relay and another wire from there the the starter relay. its easy and mine has been that way for about 12 years now

here is my build threads
