Why doesn't my Koso DB-01R meter work when the power is on?
- A
  Anthony WilsonJul 28, 2025
  If your Koso Measuring Instruments meter isn't working when powered on, several factors could be at play. First, ensure the wiring is correctly connected and that the fuse isn't broken. Then, verify that the battery voltage is over DC 12V, as an old or broken battery might not supply enough power. Also, confirm that the speed and RPM sensors are correctly wired and that the tire-size setting is accurate.

  If the fuel gauge on your Koso Measuring Instruments is not appearing or displaying incorrectly, begin by checking that the red positive wire is well connected. Also, ensure the spark plug is R type; if not, replace it. Next, check your fuel tank, confirm there is fuel inside, and verify the wiring is correctly connected. Finally, double-check your settings.
