All or nothing alternator conversion

Thank you. I've swapped back to the old one temporarily. Daily driver and all that. I will try what you suggested next time.

I am going to get the later style (vr125, the one with the triangle plug) regulator and see if that sorts it out. I'll post a follow up either way, brain permitting.

And just to corroborate (not that you need it, almost all the helpful posts I've run across have been yours) this alternator is definitely externally regulated. Says so in the Remy spec sheet.
