Re: '47 Clipper shifting issue

The only thing the Electromatic would do is engage the clutch. If turned on and below speed of approx 18-20 mph, letting off on accelerator would bring it in. On some cars, you would see the clutch pedal depress (don't remember on Clipper if it does). If the dash switch is off, then it should not come in at all. Once over the governor speed, it is normally locked out. If over that speed and it does try to come in, the direct speed switch on a stalk near power cylinder actuated by the 2-3 shift lever could be out of adjustment and staying closed or intermittently making or else a wire is shorting and a ground is being provided somewhere else in the wiring to energize the system. It is also possible if all is turned off, the vacuum supply on/off solenoid is leaking and system can not shut off. To rule that out, disconnect the input vacuum and plug the hose and try. In either case, all it would do is bring in the clutch--no different than depressing pedal-- and should not make any noise unless the throwout bearing is shot.
