|Potential Problem||Possible Reason||Solution|
|No voltage going to the clutch.||Wiring connector not seated properly.||Pull apart and re-seat connector.|
|No voltage or low voltage coming from the battery.||Check with voltmeter, battery should be 8-16 volts. (Assuming 12 volt battery.)|
|Defective charging system.||Fix charging system.|
Lead wire cut or broken internally.
|Fix or replace lead wire. If destroyed, replace clutch.|
|Fuse blown.||Replace fuse.|
|Defective switch operating clutch.||Replace the switch.|
|If voltage is going to the clutch, but the clutch will still not engage.||Coil open or shorted.||
Check coil with ohmmeter. A range close to 3 to 4 ohms should be
present at an ambient coil temperature of 70\uffffF. Replace coil.
|Check coil voltage to make sure it is compatible with the voltage coming in. (If voltage is too high, this could cause the coil to burn out.)||Change battery or coil to meet your requirement.|
Burnt out coil caused by frictional contact (rotor strike). If so, coil will be discolored, can
be cracked, burnt or epoxy can be melted.
(Example 1, Example 2)
|Clutch engages, but load will not engage.||
Rivets or springs broken.
|Key missing.||Put in key.|
|Armature could be warped because of heat due to slippage. This means it will pull in, but will slip when a load is supplied. Clutch should show signs of heat. (Example)||Replace clutch and determine why it slipped.|
