How to put in a battery switch

Recommended Posts

I have this project, and it has an electrical draw somewhere, and it would take a very long time to find it. The mechanic we brought it to said it would be possible to install a kind of shutoff switch to the battery(If we left it parked for like 2 days, we would have to disconnect the battery cables to keep it from going dead.)

Any Ideas on how this could be done, or where to buy one?

P.S. The car is a 1995 Volvo 850

E-Z to find the parasitic draw. Hook up an amp meter to the positive cable, walk away for about an hour to let the modules go to sleep, then start pulling fuses and watch to see the meter drop. Do not reinstall the fuse in the hole, if a module is on the circuit and you depower and repower it by reinserting the fuse, it will wake back up. Keep going till you find the circuit thats causing the draw, then look at a schematic and see what is on the circuit.

A battery cut off switch is a lame lame ghetto way to fix a draw

Should be looking for about 70 milliamps or less

Find the circuit. Suspect a radio. OK, disconnect the negative battery terminal and hook a testlight "inline" on the negative battery cable you just removed. Now make sure key is out of the ignition, door is closed etc. If the light glowing bright? Too much draw. Now one by one, pull out each fuse in the engine room fuseblock. After you pull out each fuse, wait about 5 seconds to see if the light goes away. If none do it, then go intot he inside fuse block. But you will need to tape the door jamb switch down so it doesnt see the open door. Same deal. Then all you need to do is pull that one fuse. Cole Hersee also makes a master disconnect switch too, but that isnt a fix, just a patch. Locate the circuit, then you can pin point the source.

Im not looking for a permanant fix, Just to get it running. Im trying to become more mechanicly inclined with cars, and this car will not go back on the road, unless I fix it up and try and sell it

The draw was occuring overnight, and the way our mechanic was testing it was by pulling out a fuse, and leaving it overnight, and then seeing it if would start up again. We gave up on that, because at the time, my sister needed the car.

Ive seen battery shut off switches for boats and RVs, thats sort of the same concept right? Shutting off the battery so it can't drain?

Well if your not mechanically inclined and you want to save a few $$ then just pull the negative battery cable off and you just made yourself a FREE battery disconnect switch! Now wasn't that easy?

it sounds like the mechanic you took your car to is a dumbass. Come on, take a fuse out and see if battery dies? We use multimeters in 2008...

summitracing.com has a quite a few different switches...heres one that looks good: http://store.summitracing.com/partdetail.asp?autofilter=1∂=MOR%2D74101&N=700+%2D107651+115&autoview=sku

i've ordered quite a bit from them and been pleased, but If I remember right, they bone you with a bogus 10 dollar handling charge no matter how much you order, which is total crap!
