Part #: 3788

Hooking up a tach on a diesel can be challenging due to the lack of ignition system. Solutions up to this point have been complicated and temperamental. AutoMeter makes the process incredibly easy and affordable with this tachometer that utilizes an inductive pick-up. Simply attach the included pickup to the outside of the alternator and calibrate with a rotary dial on the back of the tach. It will work just about any engine with a crank driven alternator, not limited to only diesel applications.

Features:

  • Traditional incandescent lighting illuminates around the perimeter of the dial
  • 12 and 16 volt compatible, well-suited with nearly every street car or race car electrical system
  • Gauge kit includes alternator pickup, bulb and socket assembly, red and green bulb covers, mounting hardware, and detailed instructions for installation
  • Autometers Race Proven Air-Core Electric Tachometers Provide Quick And Accurate Readings With A Needle So Responsive It Can Go From 0 - Full Scale In 333 Milliseconds
