Fig. 88 Actuator Operation Check:

1. Connect terminal 3 of actuator, in series with ammeter, to battery positive terminal.
2. Connect terminal 1 to battery negative terminal.
3. Solenoid should emit an audible click and ammeter should measure 0.5-0.7 amps. If not, proceed as follows:
a. If no solenoid sound is heard and ammeter reads 0 amps, check for damaged or disconnected clutch coil wiring.
b. If no solenoid sound is heard, but ammeter reads infinite, check for clutch coil short circuit.
