Work Around for Failed Alternator to Get You Down the Road
I saw this on the IRV2 forum and thought it worth passing on
"I had an alternator go out mid-trip on my 2004 Allegro Bus once.
If this ever happens to you, there is a workaround I used to allow me to finish the trip.
Whenever the ignition key is in the ON position, a charge solenoid engages that ties both the chassis and house battery banks together so that the alternator can charge them. If your alternator fails, this solenoid is still enaged and ties the two systems together. If you start up your generator set, it will power the converter or inverter/charge that normally charges the house batteries. But, when driving this power will backfeed through the charge solenoid and get to the chassis batteries. By doing this I was able to run all night with lights and wipers on and park the coach with a fully charged chassis battery."
