terminals on rectifier.
(7) If any reading is zero, replace diode.
h. Check stator as follows:
g. Check rectifier as follows:
(1) Connect ohmmeter from any stator lead to
frame.
CAUTION
(2) If ohmmeter reading is low, then windings
are grounded. Replace alternator.
Do not use high voltage such as 110
volt test lamp to check rectifier.
(3) Connect ohmmeter leads from each set of
stator leads.
(1) Connect ohmmeter to grounded heat sink
and one of three terminals on rectifier.
(4) If ohmmeter readings are high, then
windings are open. Replace alternator.
(2) Press down firmly on flat metal connector
of rectifier then reverse leads to heat sink
and same terminal.
i. Inspect battery terminal insulator
for
cracks. Replace if damaged.
