Tach setting depends on the engine/charging system, AND the Tachometer Brand/Model. Most traditional tachs will end up on a "6P setting".

There is a dial in the back of the tach. Remember what it is set to. Then turn the dial back and forth a dozen times and then select it back to where it was. Corrosion starts in the contact in the dial. Once u go back and forth few times it will make good contact again.
