I don't know exactly, not yet. I had this exact thing happen in a similar situation a few months back when I was coming home from Galveston, and it magically fixed itself, but of course I knew it would be back. And here it is. I would have to search for the old thread, I think the concensus was a bad connection somewhere.
The kicker is that it runs ok with this problem, starts right up and runs... but something is just a tiny bit off, like so tiny that only me with my 140k miles in the same seat but would notice it. Like I said, I felt/heard something off to the point where I was staring at gages, which were all normal. Until the volt one suddenly wasnt.
Frankly, I wanted to like this day and it really fn fell apart after the loss of the sweatshirt- so much so that I (insanely) wondered if the cute hippie was the devil crossing my path to curse me, or even God to knock me down a peg and remember to be grateful????
Anyway, I parked it, shut it off, kicked it, came inside to warm up because I was afraid to run any auxiliary power so I froze the whole way home, drank a beer, and tried to figure out this day. I'll look at it tomorrow but it really fs up my new year's plans, which was camping on the beach
