Alternator Alternating current question

measured separately with 2 different VOMs ) there is no AC leakage (0 mA measured with the VOM in line and in general there are no leakages anywhere in the system) which could mean that the diodes are not leaking.
Tell us how you did the leakage test. "In line", with engine stopped, no AC there because the alternator is not putting out. There might be DC current however, and that might even blow fuse in meter. Best to use clamp probe meter for current measurements.
