Test stator. Use a multimeter to check

for continuity. There should be no

continuity between stator leads (1) and

stator laminations (2). If there is no

continuity, stator is good. If continuity

is present, replace stator.

Check diode trio (2). Place negative

lead on regulator strap (3) and positive

lead to each of the three rectifier bridge

straps (4). All three readings should

multimeter leads and perform check

again. Readings should all indicate

open circuits. If all readings are

proper, diode trio is good. If any

reading is wrong, replace diode trio.
