IOD Fuse Causing Huge Battery Drain
Hey guys. So the battery in my friend'a 2003 Dodge Grand Caravan is getting drained when the car is off for any more than an hour. I've checked the drain on the battery and it is around 100-140 mAmps. I've followed the service manual guide and pulled fuses to find the culprit and it is the IOD fuse. No other fuse causes a drop in amperage. So I know what the IOD fuse does and I know most of the items that run through it (radio, done light, key fob, etc). What I can't figure out is what on this list is causing the battery drain. I was hoping somebody had access to a wiring diagram or maybe had some additional insight into what could be causing this problem. The current workaround is to either pull the fuse indefinitely or remove the negative wire from the battery when the car is off. This is obviously not ideal. Thanks!
