Re: Glow Plug wont disengage on Universal - M18 on my 1985 Catalina 27
Switch should be push to on and powers a solenoid in the glow plug circuit. Probably burned out the glow plug. Most glow plugs operate on counting one chimpanzee, two chimpanzees ,,,, ,,,, Ex Ford take 4 chimpanzees yours may differ. Usually good idea to pull old one Put an old rag over the open hole and crank a bit. Blows any possible burnt off tip out Then install new one
