Customer Question

hi, I have a 2005 quiet diesel 5500. I can start it and it will run for as long as I want it to. several hours if I want. but as soon as I turn on my air conditioning it will die after just a few minutes. it will start right back up but if I run anything bigger that a television it dies. what do you think?

I thought this was an ONAN page. So just to clarify, it is an ONAN generator in an RV. thanks, Jeff

What is the model number of the genset?
