1999 3.8 Parasitic Battery Draw
This has been a problem since late last year when the battery suddenly went dead after sitting a few days. This is my wife's car and it's not driven all winter and I had to put a new battery in it last spring. The car is stock and alternator is only a couple years old. It has the Mach 460 factory system. I've narrowed it down to fuse #27 which is the radio which I assume triggers both of the amps. With the fuse pulled the draw is almost nil and is still holding at 12.8 after 3 days so far. Before this it would pull the battery down
I know I've read about these factory amps or relays causing a parasitic draw like this but what can be done to correct the problem? This has been very frustrating to say the least let alone she wants to drive her car :icon_frown: Any help would be a huge help!

When you park it for the winter just remove the battery and put the battery inside somewhere that the cold cant get to it. Problem Solved. Any battery left sitting outside all winter, hooked up to a car that isnt being driven is gonna die.

Re install the fuse. Then Unhook the radio one component at a time until the draw disappears

Tnx Solara I'll give that a try to narrow the source of the problem down

I know that is not much help, but this is the only way I could approach it, cause I have never actually seen a new edge with the factory stereo that is drawing juice when off. If it were an aftermarket head unit I could guess that it had a wire crossed. Maybe there's a bypassed relay going to the amp? Could possibly be
