PTO Clutch Control Switch
1) Connector Voltage
1. Remove the PTO switch connector (2).
2. Turn the main switch "ON" position.
3. Measure the voltage across terminal 2 (Harness) and chassis.
4. If the voltage differs from battery voltage, the wiring harness,
fuse, or main switch is faulty.
Voltage Terminal 2 – Chassis
2) PTO Switch Continuity
1. Remove the PTO switch connector (1).
2. Check the continuity with an ohmmeter across the terminal 1 (a)
and terminal 2 (b), terminal 2 (b) and terminal 3 (c).
3. If connection does not change, PTO switch is faulty.
