C2.2 genset intermittent failure; engine control switches? 24kW marine generator

I have a 24kW marine genset. It has a problem apparently related to the start/stop switches or the control panel. Sometimes the generator only will run if the "on" switch is held down; but sometimes it continues to run if it is released. The alarm system also seems random, coming on for no apparent reason, and the alarm start switch seems to have an effect sometimes.


Anyone have expereince with this?


It is about 2 years old and has 2600 hours.


Serial number TAG01260, engine serial SAJ01216, Arrangement number C02DA60, 33hp, 24.3kW


Thanks very much.
