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.
(3)
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.
