I run the large case I think 130a
it gives me voltage after some run time and high revs, but not before. spraying things in it made no difference.
it is getting voltage from the ECU. makes no difference to tickle direct to the single pin. do have good continuity on charge wire through shutoff.
This alt was installed in July give or take. I changed one last year too. And right before Hammers, I have that one in a box marked "squeaks" somewhere as a trail spare. Either the alt or the (also months-old) power steering pump is squeaking now too. I guess I'll find out when I change it.
humbug. Lost hours to diag because I couldn't believe it, but at least it's only 15-20m to change it.
