IF PTO CLUTCH WILL NOT ENGAGE
Apply a negative ground to this terminal
Apply 12Volts to this terminal. Clutch should
activate, if it doesn’t, clutch is defective.
If clutch checks OK, use a voltmeter to measure for
12 volts at the brown wire’s terminal. First turn
ignition switch to the ON position but don’t start the
engine. Now engage the PTO switch. For the first test
put the negative probe on a good ground, not on the
white wire’s terminal in the plug. If no voltage is
measured, move on to next test.
The problem may be a poor ground on the white wire
in the clutch plug. Check by testing for continuity to
ground or check for voltage between the two
terminals. If no voltage is measured, move on to next
test.
With the PTO switch ON there should be continuity
between these two connectors, if not, replace switch.
If switch tested good, check wires and connectors
back to ignition switch and back to clutch plug.
