Cranks but won't start. Unplug ground at field spade on Alternator and it starts?

Do you have a multimeter with a 10-20A ammeter scale, and know how to use it? Try unhooking that field circuit, then insert your meter and see what that circuit is drawing, both, with key in "run" and with key in "crank"'

Explain the "unilite power wire?" Where does it get power?

I've heard some pushback on unilite, seems like they might be failure prone.

Yep well aware of all the bitching moaning whining complaining all over the internet Unilites are trash junk useless garbage. My Unilte been on there since 2009 and up till now not a single issue. Put one on my buddies 350 chevy 20 years back never a problem.

I updated the diagram several post back that shows Unilite wired in. Been like that since 2009. Checked Unilite ground zero ohms to neg battery.

Looks like my meter goes to 10 amps.
