I have what may be a dumb question but if I don't ask who would know. Is it possible to hook up a coil backwards and it work? Or, if it does would it possibly work for awhile and then suddenly quit only to work again perfectly when the wires are reversed? My son's 302 in his 78 F100 seems to be doing this and I didn't think it was possible.
A coil will work perfectly when wired up backwards unless shorted out. The easiest was to figure out if the coils wired backwards is a tacho will work when connected to the "+" terminal. Tacho feeds supposed to go to the "-" side
