GP 8 How to Check a Solenoid or Clutch
Purpose
Use this procedure to check a clutch or solenoid.
Initial Actions
WARNING
Ensure that the electricity to the machine is switched off while performing tasks that do
not need electricity. Refer to
GP 10
. Disconnect the power cord. Electricity can cause
death or injury. Moving parts can cause injury.
1.
For a clutch, check that the mechanical components are clean, free to move and are lubri-
cated correctly.
2.
For a solenoid, check that the armature and associated mechanical components are free
to move.
Procedure
NOTE: The voltages, PJ numbers, pin numbers and PWB names shown are an example only.
NOTE: When a solenoid is energized in diagnostics, armature movement is seen. When a
clutch is energized in diagnostics, the sound of the clutch action is heard. If possible, energize
the motor connected to the clutch to confirm when the clutch is energized.
•
Check that the signal changes on the ESS PWB (
Flag 1
) when the component control
code for the clutch or solenoid is entered.
•
Disconnect PJC (
Flag 2
). Check that +24V is measured when the component control
code for the clutch or solenoid is entered.
•
Disconnect PJD (
Flag 3
). Check for +24V on the LVPS.
•
Check the wiring and the connectors for the clutch or solenoid circuit.
