I've tried 2 different tachs and when i hook them up they both peg at 10,000 while the car is at an idle !
I'm conected to a switched power (Red), tried 2 different grounds (Black), and hooked to the negative side of the coil (Green).
Is there something different with electronic ignition ?
1978 Pinto 2.3 litre
I could appreciate any help !!
