ELECTRICAL Starter Solenoid & Starting System Starter Solenoid Testing (solenoid only) Purpose 1. Disconnect solenoid from the wiring harness. The solenoid’s purpose is a remote switch to connect the battery to the starter motor on the engine when the ignition switch is turned to “START”. The solenoid is used to protect the ignition switch from the high current drawn by the starter motor. 2. With a multimeter (ohms setting), check to ensure that terminals “c” and “d” are open (no continuity). 3.

ELECTRICAL Electric PTO Clutch Testing Purpose If the electric PTO clutch is not engaging or is sus pected as a cause of electrical problems, use the troubleshooting steps. These procedures will help you determine if the clutch has failed or is the cause of the electrical problem. The clutch electrically controls the engagement and disengagement of the Power Take Off (PTO) pulley. Location Coil Resistance Measurement The electric clutch is located on the PTO end of the engine crankshaft.

ELECTRICAL PTO Clutch Continuity to Ground Check Measuring Clutch Current Draw 1. Disengage PTO switch, turn ignition off and remove key. Note: Do not measure current draw if clutch has shorted to ground or if the resistance measurement is out of specification. 2. Disconnect clutch wire connector. 1. Disengage PTO switch, turn ignition off and remove key. 3. Set multimeter to check resistance (ohms). 4. Connect one meter lead to the engine, chassis or battery ground.
PAGE 126
ELECTRICAL PTO Circuit & Operation - The PTO clutch is powered by the Push/Pull PTO switch. - The PTO clutch is grounded through the Brake Actuator Module. - The PTO Clutch will only engage when: • The ignition key switch is in the ON position (engine running or not). • The PTO switch is in the ON position sending battery voltage to the PTO clutch. • The PTO switch is in the ON position removing battery voltage to the Brake Actuator Module (pin 8).
