'04 Crossfire Coupe Battery Slow Drain
Hi All,
Maybe someone can identify the source of my problem. The battery in my 04 Crossfire is slowly being drained to the point where it won't start the car. If I drive the car regularly, it will start and run daily. Only if I do not drive the car at all for about 1 to 2 weeks will the battery drain. The battery and alternator are good, and I had replaced the blower motor resistor for a continuous fan problem that drained the battery in a couple of hours. I do, however notice a sizzling, crackling sound that seems to originate near the fuze box near the battery whenever I reconnect the negative terminal of a fully charged battery. Any help will be greatly appreciated.

Re: 04 Crossfire Coupe Battery Slow Drain
In that box are 4 components :
1. the PTCM ( Power Train Control Module [ ECM ], all solid state, let's hope this ain't making noise. )
2. the BCM ( Body Control Module, also all solid state )
3. the RCM ( Relay Control Module, or K40 - all relays and fuses and a couple of diodes/resistors )
4. A tiny fan that sucks air from the interior to cool the above 3 modules.
Your best bet is to hook a multimeter in series with the negative battery cable and measure the milliamp draw. If it's above 50 ma, then start pulling fuses from the underhood fuse panel until you see a drop, you have at least found the area to investigate.
If you never see a change, try removing the fuses from the RCM one at a time also.
If all else fails, install one of those battery disconnects and just turn it off when you are going to let it sit. ( dumb solution, but it works ! )
If you are a cheap a$$ sucker like me, just keep a 10 mm open end handy and undo the negative battery cable.
( you WILL lose all the radio presets, and the dashboard clock will have to be reset )
