Onan 7500 Quiet Diesel generator

[HRF]

The generator would not start and set fault code 32 which could be low batteries. But 3 days later, it started okay. Again 2 days later it would not start with code 32. Coach is not plugged in and is in a storage yard. Batteries are not discharged and connections on batteries are clean and tight. Any thoughts on what to check?

I don't have your Genset but I would possibly use a secondary battery hooked straight to the genset before I ruled out the battery/cables. If you're positive the batteries are fully charged than you might be able to find the service manual here. My experience is that the t/s charts in the Onan manuals are pretty good.

Good luck!
