Just as Paul suggested, I plugged my unit into the wall and plugged the bus in and started the wait. Sure enough, two minutes and nine seconds later, the coach powers up. Inverters are showing good shore power, alarm is off and I'm thinking, "Let's try that again".
So it gets unplugged, alarms sound, inverters come online and we plug it back it. A little more than two minutes later, shore power light comes on, inverters go back on shore power and it's working.
I'll be more convinced when I go back out there and it's all stable and running like a the Truk man when the Low Beer light comes on, but at least it's working.
Thanks Paul for the suggestion.
