alternator circuit question

I have a 91 Plymouth Acclaim, and the alternator doesn't charge the battery. I took the alternator out and had it tested, and there's nothing wrong with it. I put a new battery in it, but it still won't charge. I checked the fuseable link from the alternator to the battery, and there is continuity. Therefore, it must be the computer.there are 4 connections on the alternatorL1: direct to battery, positiveL2: direct to battery, negativec1: small wire, logic, to computer, activates diodec2: small wire, logic, to computer, also battery ground.I want to activate the alternator continuously and put on an external voltage regulator.What must the voltage (and current), to the logic inputs c1 & c2 be to do so?I have in mind to run a potentiometer between L1 and c1, and adjust it until the alternator kicks on.The schematic shows that c1 goes to the coil of a transformer in the alternator, which then goes to one of the diodes (an SCR?)

No pun intended, I am sure.
