Hi, My question is relevant I think.
I have just replaced both alternators on my Westterbeke 33, the second
alternator was added by the PO. When I reconnected the wiring to the
alternators I found there was no wires connected to the second one. Only the
wires coming off the charging post.
The wire going to the key switch turns on the internal regulator and the wire
going to the starter provides the feedback sense voltage to the regulator so
that it can hold the output voltage constant.
These wires are needed for an internally regulated alternator. If they are not
connected,
I am going to try again with a simpler alternator question and hope someone
knows the answer:
My wiring diagram for the engine shows a purple wire connected to the Exciter
terminal of the alternator and running to the key switch and a orange-red wire
connected to the Sense terminal and running
