Beat to death alternator I have a question that has been beat to death, but I can't seem to figure out the final verdict of what people are doing recently. I got my Nova swap running, but the alt isn't charging. It's a C5 GMPP kit and has the SFL terminals. I wired 12v keyed to the L wire through a 194 build holder I had. The alternator won't charge. It also won't charge if I add 12v to the F wire. S is ran to the battery post on the back. I know 12v is supposed to burn up the L wire but I tried it very briefly just to see what would happen. If I touch 12v to it, it jumps up and charges 13.8 but won't work with the resistance method. Also there is a black line on the L part of the alternator like someone marked it from factory, not sure why. I don't want to burn it up obviously but I can't find any recent threads that addresses this either. Opinions?

The resistor I tried probably wasn't right, it's just one I had laying around from some autometer gauges. The 194 bulb is what I initially tried though, seemed to be a common solution in a lot of threads. Is it possible the bulb reduced too much and didn't activate it? May just have to order the 470ohm.

I messed around with it some yesterday and used a different bulb socket. Inline with the L terminal the alternator now charges fine. Just an issue with the holder I was using I guess. The bulb does stay lit up though once I start the motor at idle. I assumed it should go out but doesn't.
