Re: Continuous duty, non-thermally compensated alternator: options?

One suggestion: several years ago I was looking for a spare alternator (80 A Hitachi on a Yanmar 4JH2TE) partly for an upcoming voyage, partly due to intermittent charging which turned out to be... a poor connection on the alte rnator ground at the engine block (the 80A version is NOT case-grounded, that short black lead is *really* important).

What I did find was a NOS (New Old Stock) original Yanmar alternator that a shop had removed from a newly delivered engine because the boat owner wanted a Balmar or similar upgrade. Cheaper than a rebuild, perfect fit. No better than the original, but I was satisfied with it when it was working properly. You should be able to find one for about half the "chinese hitachi clone" you mention.
