I got my fried Balmar rebuilt with Balmar parts and installed and all is well. It's charging like a bull. As it turns out, my temp sensor was connected to the ground terminal which works on most alternators but not this one due to its offset position on the Balmar 621. Thanks to CMS/Rod Collins for alerting me to this issue and advising me on the best mounting position for this temp lead on the side of the case.
Here's a pic of my old port alternator. I'm replacing my working original (to me) alternator on the port side with a new single-wire alternator which has an AC terminal for the tach output on the case. The old alternator is wired with a block mounted on the back (orange and white wires) and a plug on the side marked 1 2 with the same white wire and a green wire. Both the orange and the green wire are 12V+ with the key on and engine not running.
Which is the tach output wire? What should I do with the other, unused orange or green wire?
