Before carrying out troubleshooting, check that all related connectors are properly inserted.
Always connect any disconnected connectors before going on to the next step.
Read the precautions given in TESTING AND ADJUSTING, “Adjusting stroke of governor motor lever” before
carrying out the troubleshooting.

Note:
When the starting switch is ON, the controller end is OFF, but a voltage of approx. 20 - 30 V is always
flowing from starting switch BR, so if the voltage is measured at EOI (13), there is a voltage of 20 - 30 V.
