Starter motor

Self starters have not been common for very long, today many two-wheelers are started with an electric starter.
For vehicles that can alternatively be started with a kick starter, a failing starter motor may not be the end of the world, but since there are fewer and fewer vehicles with a kick start option, the starter must always work properly.

Starter failure - what to do?

If the engine does not start and the starter motor does not turn, it is not necessarily because the starter is defective. First of all, you should exclude other sources of error:

• Check the battery with a multimeter, it must indicate more than 12 V.
• Check the starter relay: Clack test is not sufficient, it must be tested with a multimeter.
• To test the starter itself, you need to bypass the relay and check if the starter motor turns.

It may be caused by more complex problems. In this case, you should contact a specialist workshop.
