Question Help with battery power drain - where does this wire go?

Howdy folks - I have a power drain on my battery, been trying to isolate it. Checked battery and charging voltage, all OK. Disconnected alternator, diodes OK. Pulled all fuses and relays, OK. When I disconnect this 100 amp fuse in the engine fuse panel, the drain on the battery clears. What could be drawing off of this fuse (with the ignition off)?

I don't know if this 100 amp fuse is connected to the door chimer, But I had a battery drain too not to long ago and just happen to be the door chimer. Even though it's not in use when the truck is off or really anytime it was the culprit in draining my battery. Might want to disconnect it and see.

That might have been a problem on my truck some time ago. The previous owner got rid of the chime and all dome light switches. I like his style.

Too much drain. Where is the door chimer? I will kill anything that I don't need that might be the source of the drain.

It is in back of the speedo/tach/temp dash. Should be a little black box with speaker type grill on it. You can't miss it.

I think it goes to the starter if it is the one I am thinking about.

In a 97 is is behind the switches for the rear door wiper/washer on the center dash.
Same unit controls the int. lights and the rear wiper timer.

The 100 amp fuse is the main input to a number of the systems.

Removing it kills most of the other links and a few of the fuses. It is sort of like just disconnecting the battery. Getting rid of a drain by taking that out is just like removing your battery terminal, you don't have any ignition power when you remove it. You haven't really found the source of the issue (if you have an issue).

Think of the 100amp link as the "main" fuse that protects the little fuses down the line. It powers the 60 amp link to the ignition switch, the 60 amp link to the light switch, the 30 amp link to the rear defrost, the 30 amp fuse to the EFI ECU, the 30 amp fuse to the interior lamp ECU and a 20 amp fuse to the column switch for the headlight flash.

The clock and a couple ECU draws are what usually kill a 90, but it usually takes 3 weeks or so. Some go faster than others. A battery kill switch for when you plan to leave the truck sit is a nice simple install and can even help in an "oh shit" situation if you have an electrical issue.

Thanks ECR. I did separately test all of the other circuits coming off of that box, and none of the individual circuits killed the current drain, which is weird. Seems one of the other large busses would have contained the draining circuit. Argggh!

Who knows where I can order the original style OEMish/military battery switch that installs thorugh the battery box wall?
