A friend who swallowed the anchor
gave me the spare high output alternator
he had for his Perkins
. He said it had never been used.
In an emergency
I mounted it on my Yanmar
, and while its being there allowed the engine
to operate (the water pump
being driven by the same belt), it did not produce current
. So back went the old alternator
(also high output externally regulated) after the bearings were replaced. This was a couple of years ago so my memory may be faulty, but I believe I took the new one to a shop, and they said there was nothing wrong with it.
I should have tried to resolve this at the time, but other things got in the way.
I've been told that an alternator is made to charge rotated in one direction only. I'd be surprised if my Yanmar
rotates opposite his Perkins
(mine is a Saildrive
, but I don't think that matters) but is that a possibility?
Then I've read about different type alternators, P style or something, but I don't know what that means.
Any ideas out there?
