Alternators Rebuilt

[Bob & Carol Howald`]

Hi Ron: I seriously doubt that that was the problem.But??? If I
were you, and Iam not. I would disconnect or take a piece of card
board and cover up the alternator 1 & 2 reading gauge and use my
hand held voltage meter for more accurate picture as to what's
actually happening. You can go to the back of the coach and access
the bus panel where the #1 and #2 alternator connect to the
electrical grid and actually find out what's going on. Much more or
at least reliable information to be had there. Always good to see
your post, much regard's....Bob&Carol..93pt..Illinois, Warm-but going
