PTO Clutch Continuity to Ground Check
1. Disengage PTO switch, turn ignition off and remove
key.
2. Disconnect clutch wire connector.
3. Set the multimeter to check resistance (ohms).
4. Connect one meter lead to the engine, chassis or
battery ground. Connect the other meter lead to
each of the PTO clutch terminals.
5. The two PTO terminals should never have continuity
to ground and should be OPEN at all times.
If continuity is found between the clutch wires
and ground, the clutch and PTO switch must be
replaced.

has shorted to ground or if the resistance
measurement is out of specication.
1. Disengage PTO switch, turn ignition off and remove
key.
2. Disconnect clutch wire connector.
3. Set the multimeter to check amps (10 amp scale).
4. Connect the positive meter lead to the chassis
