PowerTech generator problem
A couple of suggestions:

* verify the fuel solenoid is opening - when you preheat (or start) the
engine the solenoid opens, and stays open for matter of seconds after you
disengage the start or preheat button - you'll hear clicking - it then will
return to the closed position - this solenoid is a booted device on the curb
side front of the engine.
* possible air in fuel line. have someone crank the engine while you
open the T handle valve that is inline with the fuel lines (this is located
above the solenoid mentioned in the first bullet. Opening this valve allows
excess fuel to return to the pump, purging air that may be in the lines. Some
people advise this valve should be left open a small amount.
Generally, if it cranks and gets fuel, it should start. If it just cranks
but won't start, and you're fairly sure your getting fuel, check for a bad
electrical connection, a prime area is the gang plug with multiple wires on the
curb side of the engine. Move/shake the plug to see if that helps. You can
also feel (careful) the glow plugs to see if they are warm.

PowerTech generator problem
Does anyone have a suggestion on where to start looking for the reason
my 15KW PowerTech won't start? I used it last during a trip to Florida
in January and it worked great. I tried to start it last week and it
fired and ran for just a bit before dying, maybe ran for a few seconds.
It turns over good but will not start.

Thanks,

I just had to replace the electric fuel pump on mine. I came back to
the motor home and found the gen-set off for the first time ever. no
circuit breakers popped. started it up was rough running but then
did OK. Ran all night but quit the next morning and would only try
to start. Replaced the fuel pump and has been running good ever
since. I had a spare pump from 2 motor-homes ago(15 years)and it
worked fine. Bought a new spare from NAPA, they had it in stock.

Good luck

Check your air and fuel filters.I have had mine shut down
because of air filter twice.

PowerTech generator problem
There are several things that will cause the problem. Some have been suggested.
Based on the year of the coach, the engine is probably a Kubota. This is how I
would approach the problem.
Check to see if the fuel solenoid is operating. It should click and the booted
arm should move back and forth. If it will not start.
Crack the pressure line on the fuel pump and see if fuel is being pumped to the
injector pump. There should be a pretty good stream. If not, the fuel filter
could be stopped up or the fuel pump is bad or there is no power to the pump. I
had a bad fuel pump that caused very hard starting but would let it run.
If all is well and it won't start their could be air in the system. Before you
start bleeding lines:
Disconnect the wire to the over temperature sensor and see if it starts. If it
starts the sensor is bad or the wire to it is grounded somewhere.
It probably has a low oil pressure switch. Disconnect that wire. If it starts
the switch is bad or the oil pressure in the engine is low(unlikely). Check the
oil. All from memory when I reworked my unit.
The odds are slim. One of the start stop switches is in the stop position. Since
they are spring loaded to run it's remote, but possible. Check the one in the
genset bay, it is exposed to the elements.
If it will not start I'll have to go get my book from the coach. Hope this helps

I just had to replace the electric fuel pump on mine. I came back to
the motor home and found the gen-set off for the first time ever. no
circuit breakers popped. started it up was rough running but then
did OK. Ran all night but quit the next morning and would only try

Alvie... Ihad the same problem with my 89 kabota. Turned out to be a
burnt pin in the cannon plug from the control box. The teck that
fixed mine bypassed the plug with two wires, one of which supplied
voltage to the glow plugs while cranking.I had prob for two years
before I got it fixed. Stars right up now.While cranking check
voltageon plugs....

hope this does it
