... or yet another electrical thread...
After ~3hrs all ahead flank to windward in a swelly F6, I fried my alternator.
<spends 45 mins reading previous PBO threads>
It was the original 35 amp Hitachi on a 1GM10 (so 21 years old).
I've no reason to suspect any other part of the system (batteries, Sterling booster, VSR, BM-1, etc), and I've got a replacement from my local auto-electrician.
I did briefly see 30 amps going in a couple of days before (low batteries, dropped to 15A after ~5 mins; 5A after 15 mins as expected), but we had been on shorepower the night before it failed.
Can anyone think of anything I should check before/after fitting the replacement?
(oh, and a new belt - very /slightly/ wider than the REMF-1295 previously fitted, and derided as "too thin" by auto-electrician)
The wear on the belt was obviously why I was down on power, but is it likely that alternator failure was the *cause*?
I'm considering fitting a manual cut-out switch to the field wire for occasions where I might want more motive than electrical power.
