When I installed my new stereo I started getting a parasitic battery drain, I dont know where but the battery will die after about two days. I got a bigger battery and checked the Alternator and the the diodes were good. I checked my wiring and its good. The only two wire I dont know about are the power antenna and the dimmer wires, because my new stereo didnt have those so I just taped them off. Also the factory amp has been removed and the wires taped off. I used the factory AMP ground wire to ground my stereo which is a good solid clean ground. Does anyone know what could be causing this. Thank You.
Also I pulled the AMP and Radio fuses and still get a dead battery after about 2-3 days.

 

You need to find out which fuse in the fuse block is pulling the energy one by one, then that will help you narrow it down. Unless you have a amp meter to install inline and find which one it is.

 

with that said, i just got my stereo installed 15min ago, read this, and checked my fuse box to see if any were pulling power, here is what i got, the power amp fuse was drawin 20 some volts. Also so was the power lock, parking lamps. So is the power amp fuse, for the factory stereo amp, should it be drawing any power when key is off??

Worried to wake up with a dead battery, if the amp dont shut off. Sucks cause it dont click or anything when it turns on/off.

Does anyone have a pic of the factory amp?

 

I know the amplifier on mine is located to the right of the glove box, just above the kick panel. Mine has an Infinity label clearly on it! I have been doing auto sound systems for 18 years and have NEVER heard of a 12 volt system putting out 20 volts! Does the radio shut off with the ignition? If not... you have the wrong wires. Do you need a wire guide and if so what year?

 

wouldnt mind seein the wire guide its a 99 slt.

Stereo shuts off with key.

I probally wasnt usin my volt meter correctly, it was dark.

 

Do you just take a amp meter and hook one wire to the battery and the other wire to the neg cable then pull fuses till the voltage drops? I know anything over 50-60 is a drain. Autozone checked it and found that it was drawing a whole amp.
