Ann - the closest thing i've seen to 'stepXstep' instructions is the SERVICE MANUAL. It will have a bunch of in-depth info on most aspects of the genny, but it is written for service mechanics to use on the job. That does not mean it's way over your head, but it can be involved. Unfortunately, the part of that book that I needed was not super helpful. In any case, for $20 it's a very good investment. Call your localOnan/Cummins dealer and order one. While you're on the phone, ask the nice man your question, and you just might luck out. Before you call, jot down the 3 letter code on the little nameplate and the SERIES letter. The might need this to get the right book. If possible, call from a cordless phone standing right next to the genny.
