Battery Drain Help Please
I'm looking for some electrical advice please. I have a 2005 F350 Diesel and a 2002 AF 1080 truck camper. I keep the camper plugged in to shore power when not in use. Last night while getting ready to...

I dealt with a similar problem with my truck. Sometimes the battery would die after a few days of sitting. Sometimes it would be just fine. I knew I had a random phantom load.
I eventually gave up on the basic troubleshooting and went all-in to fix it. Bought an multi-meter that measures DC amps. Also bought a 'Fuse socket connector kit' which is essentially a blade fuse replacement. This allowed me to put the multi-meter in-line on a fuse circuit. If I got any reading, then that indicated there is a draw on that circuit.
Went through every fuse in the fuse box. No luck. Finally remembered my accessories. Sure enough, I had a draw on my MSD 6a ignition box. Disconnected the box from the wire, and I still had the draw! Started tracing the wire.
Turns out it had gotten pinched between the plastic mount under the ECU and the fender. Eventually it wore through its insulation and the paint on the fender. Not enough to heat up the fuse and pop it, but enough to kill the battery after a few days.
That is the only way to trace which circuit has the draw. Multimeter I bought. Fuse socket connector.
Good luck!
