Back to the original topic, my Onan generator was clicking too. Took it in to Cummins for analysis and they found that it was the fuel pump. During the test it gave up the ghost. Fuel pump cost is $71.89. Now the generator had to be removed from my Class C motorhome in order to gain access to the pump. Labor cost was $730.00. One month left on my warranty so that was the good part. Bad thing is that if this new pump goes out right after my warranty is up there is no guaranteed time frame on this new fuel pump if that one goes bad. This according to Cummins Service Manager. Makes you wonder about this entire RV industry.
