Ran genset, now seeing 19+ volts from solar
My MH has been sitting in the driveway for several weeks with the solar panels keeping it charged. NO shore power. Today I went in to run the genset. The voltage meter read 13.6v before I did anyt...

I am sure I have confused some of you by the timeline of genset starts, restarts etc. I am confused myself, so sorry about that. I do know this: It was flashing the high voltage error code when it shut down, and I was able to get it restarted more than once in that condition. Which would suggest that the fuse was blown, yet it restarted!
HOWEVER, the chassis-house interconnect might have been energized by what its black box read as having charging available for the chassis battery from the house side. It saw voltage greater than X (I'm guessing X = 13.0 or so) and its logic probably says "if V>13.0, close the solenoid and divert some charging current to chassis battery". There would have been enough volts and current from the solar controller to close the solenoid. Then the chassis battery would have been tied in to the house side, allowing the genset to do restarts/attempted restarts.
That is my theory about why I could continue to run the genset starter after the fuse blew. It sort of wraps up all the loose ends except for why the fuse blew. I'd like to say it was just the draw of the cranking, but why did the genset run for a few minutes, then sense 19.6v and shut down? We may never know, as I plan to put a larger fuse on and go from there.
