Thread: TPI-Tech Programmable Speedometer

We get most of our components from Faria for our instruments and we have not had any issues, so I'd have to say the core parts are pretty darn good.
99% of the electronic speedo issues are sender related. Bad connectsion, incorrectly wired, missing drive gear. The best way to troubleshoot the speedo sender is to hook up a multi-meter to the sender output, spin the tires and see if you get an on-off signal or a +/- signal pulsing as you turn the wheels. From there its easy to figure out if this the sender or speedo.
