Not sure whats going on. Here are some of my voltage readings.
Battery 16.0v
back of alt 16.0v
one field wire 14.8v at reg
one field wire at reg 10.5 v
all with car running. I installed a new regulator. The alternater has very low run time. It is a chrome powermaster amp is unknown. I also put a amp clamp around the neg cable and im only reading 12.0amp. I put it around the pos cable and Im reading 3 amp? I am a bit confused as how this system works. Any insight or help would be appreciated.
