Replacement 51 amp Alternator (drawing 200360) with 12V 105 amp (INSTRO89)

[raisondeuxetre@gmail.com]

The question that I have on my Catalina C-34 1997 Hull number 1323 is that I am replacing my 51 amp Prestolite Alternator (Please see drawing 200360) with a 12V 105 amp Prestolite Alternator (Please see INSTRO89). The voltage regulator is self excited.

Per drawing 200360 the #14 GRA is (not used).
Should I just put heat shrink on the 14 GRA wire?

Per INSTRO89 I do not see any connections for the #14 LT. BLU or #14 Pink (Shown on 200360) to the exciter.  The actual alternator has a cut green wire as shown on the attached photo. This new voltage regulator is self excited.  Should I just put heat shrink on the  #14 LT. BLU and #14 Pink wire?   

What should I do with the cut green wire?

What engine is this going on?
Where did you get the replacement Alt?  Catalina Direct?

It's a M-35AC

The new alternator is from Catalina direct

They used to sell genuine Leece-Neville, now they sell  knock-offs at LN prices? Very disappointing..

CD is advertising and posting L-N documents that mislead owners into thinking that they're selling genuine L-Ns. While CD doesn't specifically claim that it's still intended to mislead.

There's another thread on here where an owner was alerted, and cancelled and returned CD's garbage and ordered up a genuine L-N instead.  You might search for that thread and do the same if you want a quality Alt in your boat.

Another alternative is a Wilson, who does high-quality rebuilds of L-N alts.

Ken's right.  I just did a search on "leece neville" - there are two pages with over 50 posts.  I recall most of them from when they were first posted.  They remain valid, many of them include photos, and many include comments from Maine Sail.  It's well worth your time to do so.
