How to test a motorcycle gear indicator using a multimeter?

The working principle of the motorcycle gear indicator is that when the gear is shifted, the corresponding gear display contact will be grounded. Whether the motorcycle gear display works normally is related to you checking the current gear .

When measuring a motorcycle gear indicator with a multimeter, resistance should be used to measure whether each output line and the corresponding contact are connected. If the gear display device is normal, install it on the engine and shift to each gear. Use the multimeter to measure whether there is continuity between the gear line and the ground. The normal situation is to shift to which gear, the corresponding gear line will be connected to the ground, so that the gear display switch can be judged and whether the contact is normal.
