Subject: RE: Header drive electrical magnetic clutch problems


Faunsdale, AL
Unplug the connector to the brush rig/swivel on the end of the shaft that the magnet is fastened to. Leave separator switch off so the magnet isn’t spinning

Have someone sit in the seat and test for voltage there. If you have voltage there, plug it back in and test at the two screws where the wires from the swivel connect. Still got 12 volts there, good test ohms through the coil from screw to screw with the harness unplugged from the swivel. Should not be very high ohms. I would guess not over 100, but that’s a guess. Need to compare with a good one.

I’ve never seen one that had too much wear to engage. There is probably a max air gap between magnet and driven plate though.
