We already tried another regulator (both are brand new). I'll try another alternator, it sure seems like this one isn't working. When we spoke to the parts place, found out that they don't deal with this supplier anymore. Wonder why, lol...
Jay,

Looking at the back of the alternator, the R terminal is on the left, F terminal is on the right. Back probe the "R" terminal right at the alternator if no voltage, swap you working alt. or replace the alternator. Has to have voltage signal back to the reg. to turn the light off.
