Thanks for the note on Balmar's plans for the MC612. I wasn't aware of that.
FYI, I actually have two of the little beasties. Just before the Annapolis Boat Show last year, the one I'd been using and which had been flawless for 6 years or so stopped working. I was singlehanding back from the Chesapeake, and anchored overnite about 35 miles south of home port. Woke up in the morning, fired up the Perkins, and ....damn...the alternator wasnt' charging at all. Zero. Zip. Did some quick troubleshooting, but couldn't find the problem, and I was anxious to get along with the tide.
Since I have a generator onboard, there was no problem with lack of charging from the engine. Came on back home. In the next few days, before I had a chance to troubleshoot the regulator further, the Annapolis Boat Show came up, and I went and talked to the Balmar reps. We kinda decided the regulator had "packed up", and they offered to sell me a replacement at a very favorable price. So I took them up on the offer.
When I finally did get around to troubleshooting my old one, I found some questionable connections in the in-line fuse connections, and I found that the program had somehow "dropped out". After fixing the fused connections, it was a simple matter to use the magnetic wand to reset the desired program for flooded deep-cycle batteries and...bingo...back in business. The old MC-612 is working flawlessly as it always has, and I have a spare one in the box in case it ever really gives up the ghost. Or, I suppose, in case I add a second alternator :-)
