Generator

[George Lowry]

Dave,

From what I have learned from my own experience and from writings on another
forum by an Onan Generator repairman, you need to hold the stat switch until
the alternator is putting out enough power to hold the fuel valve open. If
you release it as soon as the engine fires, the fuel solenoid will go to the
off position. It is only the battery power that is keeping it open while
cranking.

As soon as the engine fires, the bendix should disengage and the starter
spin freely. It only takes a couple of seconds for the power to come up
enough to hold the fuel solenoid....

Hope this helps.

Bill,

I replaced the starter solenoid, so I think it is primarily having to crank
too
long. The starter doesn't seem to stick when I let off as soon as the gen
fires. It
fires quickly but does not stay running but a few seconds. About the third
or
fourth time it continues to run. I have replaced the filters. Everyone I
have
mentioned it to suppects air in the line. Thanks for the input.
