ANOTHER Onan DJE generator starting problem! (Sunday)

Something strange happened today. My onan generator started, ran for
like 2 seconds, and shut down, Then it just would not start, even if I
depress the overspeed button. Upon investigation, it was found that
the solenoid that I cleaned and oiled yesterday, just would not pull
in and therefore the injection pump was not working. If I attempt to
start the engine and siimultaneously pull on that solenoid, the
generator starts and produces nice 60 Hz of electricity.

For some inexplicable reason, this solenoid seems not to be working
today. It is not stuck and moves smoothly when I push on it. What
gives? Any thoughts?

thanks

You may have burnt it out. The buzzing that you experienced in the early
attempts to start may have buggered it. Resistance tests on it will will
tell the story.

Is there a fuse in that circuit that may have blown?

There IS a fuse or Circuit Breaker that does protect the Safety
Shutdown System on the DJx series gnesets. So you do need to check
that. Also if you have low or no oil pressure the solenoid will
not pull in, as well as High Block Temp. These sensers can all be
checked with a VOM. The diagram of this systemis be in the
manual, and is straight forward. Also note that the solenoid has
TWO coils in it, and only one is used to hold it in when the
engine is running, while both are used to pull it in to start
the engine. There is an Internal Switch that drops out the
second coil once the plunger is fully pulled in.
