•
Check the stator coil resistance as follows:
○
Stop the engine.
○
Disconnect the alternator connector.
○
Connect a hand tester as shown in the table.
○
Note the readings (total 3 measurement).

If there is more resistance than shown in the table, or no
reading (infinity) for any two leads, the stator has an open
and must be replaced. Much less resistance means the
stator is shorted and must be replaced.
•
Using the highest resistance range of t he hand tester,
measure the resistance between each of the black leads
and chassis ground.
Any reading less than infinity (∞) indicates a short, neces-
si
tating stator replacement.
If the stator coils have normal resistance, but the voltage
check shows the alternator to be defective; then the rotor
magn
etism has probably weakened, and the rotor must
be replaced.
