We had a similar problem when we tried to plug in our 78 Minuet into our garage circuit through a 15 amp ground fault receptacle. Instantly detected a gound fault as with many motor starts and disconnected. When we ran a 75 ft. #10 extension cord to a non ground fault 15 amp outlet we had no problem, even with the longer #10 extension cord. Hope this helps.
