How to check the fuses

From Ninja250Wiki

Use a test light; it's fast and easy.

Okay, if you don't own an automotive test light, go buy one. They look kind of like a pointy screwdriver with a wire coming out of the end. One should set you back about five bucks.

  • Turn all the switches on the bike to the "on" position (ignition, kill).
  • Connect test light to a handy ground (brake pedal works well).
  • Double check the battery and test light by tapping the test lead against the positive (red) battery terminal. It should light.
  • LEAVE the fuses IN, but pull the lid to the junction box (L shaped thing under the right side cover).
  • Touch the test light to each fuse terminal from the back side of the fuse. There are two terminals per fuse.
  • If the light doesn't light on EITHER fuse terminal, there is something circuit-related wrong.
  • If the light lights on BOTH fuse terminals, the fuse is good and the circuit has power.
  • If the light lights on only one fuse terminal, the fuse is blown.

This is faster, safer and more reliable than visual inspection. You can do the whole bike in well under a minute and make no errors.

Oh: There are a couple of spare fuses in there. Obviously, they don't need to light.
