Starter Solenoid; Testing - Toro TITAN HD Service Manual

Starter Solenoid

The solenoid is a remote switch that connects the battery to the starter motor when the ignition switch is turned to
START. The solenoid protects the ignition switch from the high current drawn by the starter motor.

Testing

1. Disconnect the solenoid from the wiring harness.
2. With a multi-meter set to the OHM or Continuity setting, check to ensure that terminals C and D are open (no
continuity) (Figure 14).
3. Apply 12 volts (DC) to terminal A and ground terminal B. Terminals C and D should now be closed (continuity)
(Figure 14).
