Description

The Alternator Tach which is also called the variable ratio tachometer, is hooked up to the AC output terminal on the alternator. This terminal can be marked in a variety of different ways: AC, AUX., S, R, TACH, or nothing at all. Once installed, the tach is then calibrated to that specific engine by using a shop tach or a known “no load” governor speed. The white label on this tach gives the formula: [Crankshaft pulley dia./alternator pulley dia x NO. of Alt. Poles = N] “N” is used to determine the correct switch setting. Another adjustment on the back allows for fine tuning.

Please check the type of RPM signal your engine has, we have all three tachometers available for purchase.
