Okay, I tested again with different ground points and I'm getting 2.4V with the car turned to "On" and 3.8V with the car running.
I also tested both the "cigar lighter" and "power socket" connections at the kick panel and I'm getting 2.4V as well. That's a lower reading than yesterday so I think the problem is getting worse.
It looks like the problem is further upstream. According to the electrical diagram in the service manual (PWO-2) the next thing up is fuse block/junction box M1 (PG-112)in the engine bay. It looks like M1 is a single chunk of fuses that can only be removed as one piece. Looking through the window at the top of the fuse block it doesn't look blown. Do I have to replace this whole thing to be sure?
The electrical diagram breaks down the M1 fuse block further (PWO-3) but it's beyond my understanding of electrical diagrams.
Any suggestions?
