Alternators Rebuilt

[ronmarabito2002]

Well: I checked out the (6) relays and all of them function
correctly, so the problem has to be before the relays, like a circuit
breaker or could be at the switch. I'll keep looking.

I can send you the schematic later today, when I have a minute to
scan it.

Everthing has been fine but I need to check the alternators with a
multi-meter periodically.

else, perhaps the prior owner of his coach stated that the switch did
not work properly because the alternators were not perfectly matched
up or something like that, and BB installed some kind of delay
wiring. I do not recall seeing a post as to the final results.
Perhaps he can let us know.
