Unusual Electrical Problem!

How did you make out. I've never heard of a polarity reversal. That sounds
like the worst thing that could happen!! Hope you've been able to work through
the problems OK....

extreme fluctuations in voltage in both the engine and coach voltage. After
rebuilding the alternator (again), the chassis voltage is solid. The needle
doesn't shake a bit. The coach voltage needle varies by .5 to 1 volt down from
the chassis voltage. I would call it a flicker. When the main battery switch
is off, it reads the same as the chassis.

Any suggestions would be appreciated.
