Onan Marquis Gold Quiet Gas Generator 5500 Watt by Cummins Onan Questions & Answers
Onan 5500 marque gold turns over but, won't start. fault code is 32 but, batteries ok, air cleaner ok, fuel pumping, oil changed, won't start
Code 32 is a low cranking speed sense. You didn't mention a Spec # which would help. You say batteries are ok, but the generator is not getting enough cranking amps or voltage to maintain the control properly. Check, battery voltage, wiring, any in line isolation solenoids, check generator solenoid, also make sure there is no mechanical binding on the generator, a good way to do that is remove the spark plugs DISCONNECT THE BATTERY to prevent starting, underneath where the air intake is under the alternator is a plastic plug, remove that and you can put a socket I believe 3/4" up onto the alternator shaft and rotate the engine, if it tuns freely there is no binding, if you feel it is hard to move, check the drive train, belts, pulleys underneath (A lot of work, best to take to a dealer if it is mechanically bound)

Many people buy the RS units of the net, only to find they have been stuck with warm weather models, and they don't start. Does it show a code, or a code 45.
