Inverter and Generator Problems

[Gregory OConnor]

Maybe a ground problem with a bank of batteries??? when you turned
on the ig switch you may have tied both banks together and found a
ground???? the 'ign switch on' thing may also only be a way around
the problem,, like a 110V transfer issue that is only bypassed at
that (ign on)combination of events. I would repeat the synario
that shows issues and check batteries to ground. The 'radio stayed
on thing' kinda makes you think the relay that powers things like
the radio when the ig switch is turned has an issue. It could also
be somthing like a HWH pump stuck on and not spinning and burning
up all the power, or one of those big relays sucking major amps?????
watch out for operating the engine on low batteries, it will add new
issues with the cummins computer.

With the 'engine shutting off' thing and no obvious repair to be
found, I would seek the help of a tech befor it become a
intermitting issue. I dig holes on rock cliffs teathered to a crane,
climb 200 foot 1/1 slopes using the bucket of my excavator and sat
through 5 audits in as many years without even a sweat on my brow
but last month my bus kept shutting down on the freeway and I was
visably shaken.

A good tech will love your list of events.
