Re: Grey tach wire at motor
Yes, Hopefully it can buy you some time for the 4th of July camping trip. But if not, the consequences are drastic.
I'm assuming that the tachometer does not function when connected normally but does if you simply transfer that gray sensor wire to a stator yellow lead. If so, the water cooled regulator/rectifier assembly is faulty. Following are the few last paragraphs of my test.
"If so, connect the gray wire you removed previously to that yellow/gray terminal. Start the engine and check the tachometers operation, and if the tachometer operates as it should, then the regulator/rectifier is faulty and will require replacing. If the tachometer is still faulty, replace the tachometer.
If neither of the yellow wires from the stator is yellow/gray, and neither is attached to a yellow/gray wire, then attach that gray tachometer wire to either yellow stator wire, then the other yellow wire, checking the tachometer operation on both connections.
I've found this method to be a quick and efficient way of finding out which component is faulty.... the tachometer or the regulator/rectifier. It sounds drawn out but really only takes a very short time to run through. "If the water cooled regulator/rectifier proves to be faulty, don't put off replacing it as they have been known to catch on fire with disastrous consequences."
