You can never have too many good tools. Our popular tester is now on the 3rd edition (2021). This Digital Tester reproduces the signal type and frequency that replicates the signal that comes from the vehicle's tachometer and electronic speedometer signal sources.

A must have tool for testing and repair of late 1960's and early 1990's tachometers and electronic speedometers.

Fast and simple set-up - takes @ 1 minutes to set up and begin testing.

This Digital Tester produces:

Product Note 1: This tester is compatible with tachometers that are driven by a circuit board.

It is also compatibly with many electronic speedometer's that use a pulsed signal to provide speed information to the speedometer.

    The only Tach tester that I know of that can test it outside the car, works great. A dial would be better than buttons.
