Amprobe TACH-20 Problems and Solutions

some common issues and problems with the Amprobe TACH-20 tachometer, along with solutions provided by experts:

  • The tachometer doesn't turn on. This is usually caused by a dead battery or a blown fuse. To check the battery, connect a multimeter to the battery terminals and check the voltage. If the voltage is below 12 volts, the battery needs to be replaced. To check the fuse, locate the fuse box in your vehicle and look for the fuse that powers the tachometer. If the fuse is blown, replace it with a fuse of the same amperage.
  • The tachometer reads incorrectly. This can be caused by a number of things, including a bad sensor, a loose connection, or a dirty sensor. To check the sensor, disconnect it from the tachometer and check for any obvious signs of damage. If the sensor looks good, reconnect it and check the connections. If the connections are tight and the sensor is still not working properly, the sensor may need to be replaced.
  • The tachometer is intermittent. This means that it works sometimes but not others. This can be caused by a loose connection, a dirty sensor, or a bad circuit board. To troubleshoot this issue, you will need to check all of the connections and clean the sensor. If the tachometer is still intermittent, you may need to replace the circuit board.

Here are some additional tips for troubleshooting common problems with the Amprobe TACH-20 tachometer:

  • Make sure that the tachometer is properly calibrated.
  • Use a fresh set of batteries in the tachometer.
  • Try using the tachometer on a different vehicle to see if the problem persists.
