Well, we found the source of our electrical "glitch" today. It was a reset
breaker tripping because the alternator was sending 30 amps to an
improperly wired battery. I had had my non-technical "hands" put a new
battery back in the generator compartment, but failed to watch over his
shoulder or specifically ask him to test his work. Well, he hooked the
battery up backwards. All was fine until we started up the coach to go have
the new tires put on. With the engine running, the alternator, through the
isolator, was trying to send current back to top off the new battery. Since
the 10 ga. wire running from the isolator to the rear battery was also
hooked to the negative battery terminal, it burned the battery terminal,
ruining the battery, before tripping the reset breaker. As the breaker
cooled, it would try again to send current to the back, tripping again.
Hence the "glitch" posted earlier. Good thing we had added the breaker. I
suppose it could happen to anyone, but I'm getting more than my share.

Another lesson learned. When having work done by non-expert "helper",
assume nothing and supervise constantly.

You were very lucky you had the breaker, batteries can blow up from this....
