Is there a Honda mechanic who reads Boat Bits...?

Is there is a Honda mechanic, boffin, geek or hobbyist in the house?

We are having some intermittent issues with our much loved Honda eu2000i and need some sage advice...

The story so far... The red light (overload) comes on with nothing plugged into the generator and no power to the outlets. Looking inside nothing looks amiss and all cables seem to be in good shape with no evidence of excess corrosion or shorts. We replaced the circuit breaker just in case but nada... It does, however work some of the time...

God, I HATE intermittent faults!

If you have an idea drop us a line...
