Westerbeke 7.6 BTD alternator

[kcarrothers]

I have a Westerbeke 7.6 BTD diesel generator, circa 2000. The alternator was not charging, and I managed to get a local shop to make a couple of new bushings, put in two new bearings, and got it running again.

I am looking to find a replacement, other than the Westerbeke which sells for almost $400.00. The existing alternator has no plate on it to indicate the model, or output, or anything else. The only marking on the thing is "Mitsubishi". The alternator has two "ears" for the mounting bolt, approx. 2.5 inches apart, and one hole on top for the tensioning bolt.

Can anyone tell me if they know of a cross-over number for an alternator that would fit this unit?

Thanks!
