Alternator Anomaly - Problem Solved

[Stu Rasmussen]

Thanks Bruce - having that document cleared everything up.

Turns out the 2-wire connector with battery on one pin and dashboard
indicator on the other was backwards.

That's the way the coach was when I received it and having your provided
schematic and thereby knowing which terminal was #1 and #2 it was a
quick fix to reverse the connector.

Strangely enough, this connector can be inserted into the alternator
either correctly or 180 degrees out - it slips in nicely either way.

Not quite idiot proof. At least not for this idiot.

Methinks that alternator PDF should be added to the Flash Drive. Worth
its weight in platinum!

Thanks!

That ORIGINAL connector was polarity conscious. But these coaches have ALL
been altered from their original state, some everywhere you look, some not
so much.
Just about the time we think we have our coaches idiot proofed, along
comes a better class of idiots to disprove that theory. The FACTORY wiring
diagrams are most often correct. Especially Ken Henderson sons large print
versions. Double check EVERYTHING.
