Hi all, can some kind soul enlighten me on ignition / tach signals.
If I have a 4 cylinder tach connected to the neg of the coil with no conversion logic in series, would I expect the reading to be half or double of what the actual RPM is?
Web search shows conflicting info. Some say half, some say double.
Cheers
Rob
