Rectifier
1. Check the continuity across each diode of rectifier with
resistance range of circuit tester.
2. The rectifier is normal if the diode in the rectifier conducts in one
direction and does not conduct in the reverse direction.
IC Regulator
1. Check the continuity across the B terminal (2) and the
F terminal (1) of IC regulator with resistance range of circuit
tester.
2. The IC regulator is normal if the conducts in one direction and
does not conduct in the reverse direction.
