Re: Electromatic clutch operation

There should be two lockout switches and one will not affect the other--just will prevent that particular function it controls from operating. The OD switch is on the lockout handle and the EC should be in dash labeled clutch or trans.

Randy Clipper47 is correct in the governor description and wiring-- if those are wrong, neither should be working. Standing still, the governor provides ground to the clutch relay EC so that is operational until it reaches speed. At that time, contacts switch and ground is supplied to overdrive to light the light and prepare solenoid while at same time EC relay drops out so clutch is no longer able to work. Here is a pict of a Packard governor showing the wires for each and location.

EDIT: My apologies to Clipper 47 for calling him Randy instead of Dave. That's what happens when down to one brain cell & miss your nap.
