IMPORTANT:
noid terminals before proceeding with this test.
Use a digital multimeter to measure resistance.
Put on e me ter lea d on th e st arter p ositive (+)
cable terminal an d th e ot her lead on the battery

Apply B+ to te rminal "A" of solenoid and grou nd
(NEG) to terminal "B" of solenoid. Measure re sis-
tance between the starter positive (+) cable termi-
nal and the positive battery (+) cable terminal.
The solenoid must close with an audible click.
•
Meter must show continuity (low reading).
•
If met er shows no con tinuity (high reading),
•
replace the solenoid.
After re-installing the solenoid, coa t all wires a nd
