I have a 1968 Ford 4000 3cyl gas burner. I replaced the generator with the alternator conversion kit the other day and hooked up the tachometer. Initially when I turned the engine on it showed it was idling around 1,000RPM. I turned it off to finish the install and when I fired it back up the tach read 1,000 but then it gradually started sweeping higher and eventually pegged out. This is while the engine is at idle. It was late last night so I quit messing with it and went to bed.
I know the tach cable is spinning. Is my gage messed up somehow? All I did was replace the generator with the alternator conversion. Is it possible the gear drive is wrong on the alternator and spinning it too fast?
Thanks for the help.
