Before I read the instructions and learn for myself, something so simple I should be able to figure out the old fashion way by trial and error. Simply pushing the start button to start our 7500 Onan generator seems all that is reqd. However the manual makes reference to having the LP gas valve open. What is the connection. Ours appears to operate on diesel fuel. Is there a need to have this valve open or am I stupid or what. It says to have all of the circuit breakers off prior to starting. Surely all of these precautions are not "totally" necessary. Can I assume that I'm ok to start this unit with the only requirement being that I am not plugged into an electrical supply line be that 30 or 50 amps. Too lazy to read the instructions. Hoping to learn the basics from someone who has been there, done that. Thank you for your help. Keith

For your year and model coach, LP generator was standard. Your Onan diesel was listed as a option.

Thank you. That explains it. Is there any other secrets other than push and hold button to start with respect to circuit breakers and fuses? Will start reading the manual shortly. Thanks again. Keith

We have the diesel Onan in our 01. I just push the start button and hold it in as it will need to warm the glow plugs. After a few seconds the starter whirs and she starts up. Let it idle for a few minutes before you throw a load on it. I do not shut off any breakers before I start mine. Just make sure that it has been serviced recently, if you don't have the service records, I recomend having it done before you start it up.
