Bob, get a DC clamp meter. So much easier.
I wonder if the smell is a a ventilation door actuator that gets stuck on and resets itself once the battery goes dead. I would not think it would happen with the key off but who knows. It certainly sounds like a electrical part is hot but not burning.
Yes, the DC clamp meter. It was actually on my list of things to buy before leaving on the trip. Never did get it, so had to use my old multimeter..
Agree with the something got hot. Trying to determine what is the hard part. Something stuck on, causing a hard drain on the batteries. Smell in the AC vents is the only clue I have.
Years ago I had the cab fill up with a similar smell and smoke. So bad I actually pulled over on the highway and bailed, thinking I was on fire. Turned out to be the fan speed control on the heater box. Apparently there was a recall on it years ago. I put a new one on and all was well.
I've checked everything, it all works.
