My original problem is that the car would die if not started for about two to three weeks, i took it into my auto tech class and tested all the fuses with a DMM looking for an excessive drain anywhere my 7.5 Radio backup fuse is draining 0.1 when read on a DMM, ive pulled the fuse, but how would i go about fixing this problem? it has an aftermarket cd player in it but the drain was still occuring with the stock cd player, any advice would be appreciated.

 

What im asking for is now that ive found the drain what should i be looking to do as in to repair the problem. what things need replacing or more testing?

 

Unplug the items protected by the circuit to see if the amps drop from 0.1 to ~0.01.

It looks like the ECU, TCU, radio, and clock are on this circuit.

 

Aftermarket CD player...
Was any creative wiring done to allow that to run while the key is turned off? Maybe any separate amplifiers that might be drawing power all the time?

 

the only wiring i did on it was to convert the stock wiring harness to the one the one that fit the new cd player. But the probem would still happen with the stock cd player in the car, no seperate amps or any other mods, im going to take it back into my auto class and test to see if anything is draining the battery when car is off

 

Back to unplugging things on that circuit, until you find one that stops the drain. I was just suggesting additional places to look especially if you weren't the person who installed that stereo.
