Rotor Slip Ring Test

1. Check the resistance between the slip rings.

There should be 2.9 ohms.

If resistance meets the specification, go to step 2.

If resistance does not meet the specification,

replace the alternator.

2. Check that there is no continuity between the slip

rings and the rotor or rotor shaft.

3. If the rotor fails either continuity check, replace the

alternator.
Stator Test

1. Check that there is continuity between each pair of

leads.

COIL CORE

2. Check that there is no continuity between each lead

and the coil core.

3. If the coil fails either continuity check, replace the

6. Check for continuity between the terminals of the

combination switch harness connector in each switch

position according to the table.

If there is continuity, and it matches the table,

the switch is OK.

If there is no continuity in any positions, go to

step 7.

7. Carefully remove the set/resume/cancel switch cover

by prying between the cover and the switch in the
