I need help, 84 lx conv 5.0

[thalt20]

something keeps draining my battery. the alternator and battery are brand new. I just hooked up a CD player and I was told that it could be a wire that is getting constant flow even after the car is off. Does anyone know where i should look and what I should look for??

Look for frayed wires going thrrough the firewall, especially stereo/alarm cables. Been down this road before.

if this started after the stereo install I would think that its a posible cause. one way to check that is to take a multimeter, disconect your pos cable from the bat. set the multimeter to amps. place the red lead of the meter on the bat. place the black lead on the pos cable. with everything off (even the hood light) the meter should read less than .2 amps. any thing more than that is considered a paracitic drain. Have a buddy pull fuses (starting with the stereo fuse) until you see the reading drop on the meter. That would be the circut with the draw. I found a defective stereo causing the bat to go dead on a friends car. hope that helps.
