Alt switched on wire to coil +

I have a denso alternator and it requires a always hot and a switched hot to operate the internals of it, I'm not talking about the charging heavy gauge wire


incorrect; what you have it wired up as and what it requires is two different things in this case; denso alternators get wired the same as a 2 wire Chrysler alternator (3 if you count the main postive). If you have it wired up with two positives and the main heavy gauge positive its not correct. if you have it wired up any other way your sure to burn the alternator and other electronics out fairly quick

all alternators from the two wire Chrysler ones up to modern ones use the same wiring setup; only difference is modern ones are controlled by the ECU/PCM instead of a stand alone voltage regulator

they require a 12-14 gauge switched positive; a field wire coming from the regulator (as well as a switched positive to regulator) and a main heavy charging 6 or bigger gauge positive
