Electical Draw

[Slim]

Seems My FSJ has an electrical Draw, the main battery every couple of days is stone dead, ,,I changed the battery and it does it also to the 2nd battery ,.,

My question is ,, is there an easy ,,way to find it,, there is soo much electrical and to go piece by peice will be a killer,, ..Someone mentioned ,, to find it ...pull fuse by fuse and test that way ,,,but how do i test, ....\

the only thing I have changed i nthe last week or so was adding a stero ,,, so even if i remove that, how do i know if it was the problem

If there is a draw, then usually when you connect the battery there is a little spark. You could use that as a little test for now. I don't know any other ways to do it, until someone out there who is a geniass and tells the both of us ;D

use your multi meter and pull the ground wire off and run it between the cable and the wire checking for amps. if it reads any with everything off then start pulling fuses until it goes to near zero.

If it does not drop after pulling fuses then the problem is in the wiring between the battery and the fuses.

hey i found out what I think was the problem ,,, seems the stereo was the draw ,, just wired it differently seems ok so far ,

thanks for the help

Just remember that your stereo needs a constant 12 volts for any of the presets,ie radio channels, bass and treble levels along with the fading from front to rear. If you have it only wired to an ignition source you will have to set those everytime you turn off your truck.
