Just came in, with the powermaster proof sticker on the back, 94amp @ idle 142 @ highway speed, big improvement over the old 94 @ highway lol. Anyway, I got a wiring pigtail from painless, to plug into the new alt. One question though. It came w/ a resistor and no instructions. What is this resistor for, and where does it go? I remember when I was looking around for info on alternators I saw some stuff about using a resistor if you had an alternator light. All I have is a voltmeter, so do I need the resistor? http://www.painlessperformance.com/webcatalog/catlarge/30707.jpg that is the pigtail I got btw, since Im changing to a cs130 alt from the 10si.
