5. See the PTO Clutch Electrical Specifications chart.
1. Park the machine on a level surface and disengage the PTO. Stop the
engine, wait for all moving parts to stop and remove the key. Engage the
parking brake.
2. Disconnect the clutch wire connector.
3. Set the multi-meter to measure resistance (OHM setting).
4. Connect one multi-meter lead to the engine, chassis or battery ground.
Connect the other multi-meter lead to each of the clutch connector terminals.
5. The clutch connector terminals should never have continuity to ground and
should be OPEN at all times.
6. If continuity is found between the PTO connector and ground, the PTO clutch
and the PTO switch must be replaced.
Note: Do not measure current draw if the clutch has shorted to ground or if the
resistance measurement is out of specification.
