Thank you Will. I checked the 50- Amp shore cord. Prevost had replace teh end after they broke the original and the ground line was cut too short and had come off the connector.

WE NOW HAVE 50 AMP SERVICE.

The Iota 24 volt Charger still trips the breaker.

Charged the 12/24 v chassis battery bank 4 batteries all night.

The two 12v batteries are reading 13.4 and the to 24v batteries are reading 10.5 is that right or do I have a bad battery.

I am still charging the batteries and will try to start the bus in the next few minutes.
