• PTO switch test.
The PTO switch is a push/pull switch with normally open and closed contacts. Test for transfer of
power with a voltmeter. The switch contacts should be tested using an ohmmeter after discon-
necting the wiring connector.
• Diode test.
The diodes are tested with an ohmmeter set to diode testing. Voltage must travel in one direction
only. If voltage travels in both directions or there is no voltage at all, the diode is faulty and must
be replaced.
