HELP--- generator wont stay running

[Peggy & Ed McStay]

gen will start and run for about 2seconds then stop. what is happening
is the start -stop selonid closes off the fuel to the injector pump.
now i can make the thing run if i reach over and hold the cutoff lever
on the injector pump open. it will run all day. have looked at the oil
pressure safety switch. have disconnected it and tried to run gen with
the same results. what am i not looking at. need some ideas

Ed,

Try putting a charger on your generator battery and see if it will keep
running. I had that same problem once and found out the solenoid wouldn't
stay in due to low voltage. Just a thought. Are you guys going to make the
Xmas L.S.B. rally in Kerrville?

chet thanks for the reply. the battery is full charge and will
recheck the voltage at the solenoid while starting it. yes we will be
at the rally. we have already made reservations. again thanks.

Ed,

When you hold the solenoid open manually, does the generator provide
power to the coach?

If not, your problem is either the voltage regulator or the brushes.
Check the brushes first! I had the exact same problem as you with no
power to the coach, & I made the mistake of just buying a new voltage
regulator because it seemed easier to replace, $180 and it turned out
it was the brushes, $20, and they were actually easier to replace once
I found them. Now I have a spare voltage regulator I didn't really
need.

If you DO have power to the coach when you force the generator to run,
then your problem is likely the coolant temperature switch or the oil
pressure switch.

I'd put my money on your brushes...

ryan- when i force the generator to run it does furnish power to the
bus. i have also removed the wire from the oil pressure safety switch
and the water temp . still cranks right up and then dies as the start-
stop solenoid closes. ed mcstay

Hi Ed:

The fuel solenoid is held open by power from the run contacts on the start
solenoid on top of the starter and the contacts internal are bad. Replace
that start solenoid and your problem should be cured. Be sure to re attach
the wiring to the safeties.

Safe travels,

Ed:
My generator was doing the same thing. I had a leak on my linkage of my
governor, so I got it rebuilt. When I reinstalled it, it was much more
difficult to operate and the shutdown solenoid would not pull in, if I pushed it
in by hand then it would stay in.
I then encountered another problem where the generator would shut down after 30
minutes of operation. It was traced to a sensor near the radiator, a temp sensor
I believe. Finally, it would quit altogether and not start up.
The radiator fluid was just covering the top of the rad, but I guess that was
not enough, as when I filled it to the top, I have not had any problems since.

So what I have to offer is four checks -
once generator is running - does your fan turn? If yes, then continue below, if
no, then I would start with looking at the generator part.
If yes, check for full radiator,
check to ensure closed continiuty of oil pressure switch when stopped and that
it opens with pressure.
disconnect the water temperature switch, for the test.

>mr. ralph fullenwider- THANKS VERY MUCH--- oh i do love this web
site. if it were not for the site and the fine people that belong to
it i would have to sell my bird. thanks to all who responded to my
shout for help. this is about my 5th time to be in trouble and have
my self saved by the good folkes of this site. RALPH you are the one
that had the correct answer to my problem. i installed a tempory wire
from the battery to the start stop solenoid with a switch in line. as
i started the generator i turned the switch on to supply 12 volts to
the solenoid,generator ran great. while it was running i checked
voltage at the run contact side of the starter solenoid,no voltage.
as per ralphs idea i will replace the starter solenoid. i may even
have one in all my spare parts, will have to look. again thanks to
all who responded and may all your travels be safe.
