Solenoid Tests

NOTE: DO NOT leave 12 volt test leads connected to solenoid for any time over what is necessary for performing
each of individual tests. Internal damage to solenoid may occur.
Disconnect all leads from solenoid including positive brush lead attached to lower stud terminal. Remove mounting
hardware and separate solenoid from starter for testing.

To test solenoid pull-in coil/plunger:

Actuation
1. Use a 12 volt power supply and 2 test leads.
2. Connect 1 lead to fl at spade S/start terminal on
solenoid. Momentarily connect other lead to lower
large post terminal.
When connection is made solenoid should energize
(audible click) and plunger retract. Repeat test
several times.
Continuity
1. Use an ohmmeter set to audible or Rx2K scale, and
connect 2 ohmmeter leads to 2 large post terminals.
2. Perform solenoid pull-in coil/plunger actuation test
and check for continuity. Ohmmeter should indicate
continuity. Repeat test several times.
Condition
Solenoid fails to activate.
No continuity is indicated.
Plunger fails to stay retracted.

To test solenoid hold-in coil:

Function
1. Connect a 12 volt test lead to fl at spade S/start
terminal on solenoid and other lead to body or
mounting surface of solenoid.
2. Manually push plunger IN and check if coil holds
plunger retracted. Do not allow test leads to remain
connected to solenoid for a prolonged period of time.
Continuity
1. Use an ohmmeter set to audible or Rx2K scale, and
connect 2 ohmmeter leads to 2 large post terminals.
2. Perform preceding solenoid hold-in coil function test
and check for continuity. Meter should indicate
continuity. Repeat test several times.
Replace solenoid.
