Powertech Generator --engine not running right. - erniecarpet@... - 06-05-2007 08:23
Pete- do you have a separate Racor filter for your generator. Maybe its a
fuel starvation problem?

Powertech Generator --engine not running right. - Pete Masterson - 06-05-2007 12:19
Yesterday and again today, the Powertech 15kw generator started
acting up. The problem seems to be the Kubota diesel engine. The
exhaust is black and sooty and the engine isn't putting out full
power (noted that the voltage had dropped down to 100 vac from the
usual 120 vac)
I changed the air filter last summer -- solving a sooty exhaust
problem (without any loss of power) at that time, but this seems more
serious. A couple of weeks ago, I started the generator, I thought
perhaps, prematurely without allowing the glow plugs to run long
enough as the engine was clearly stumbling and not running on all
cylinders.
Looking at the engine, it appears that on injector has been replaced
(from the look of the paint, etc.) so the engine may have had
problems in the past.
I'll call Powertech tomorrow, but I'd appreciate any thoughts anyone
may care to offer.

Black exhaust is overfueling. This could equal underairing. I'd check the air
filter again to
see if it is clean. The other factor to consider is the elevation. Denver air
is thin enough
that unless the engine has an altitude compensator of some kind, you may be
running rich
simply due to the elevation.
Diesels Only on West Alameda is a good shop if it turns out you need mechanical
service.

No Racor for the genny. I replaced the fuel filter (a spin on one)
last summer when I changed the air filter. I have a spare with me ...
I can put it on...
But with all the soot and smoke, it seems like there's plenty of fuel
-- it's just not burning right.

I considered the altitude. I had a bit of black smoke when I was
through here last year when I bought the coach ... but this is a
_lot_ more black smoke. I was getting some while in Texas -- some
3000 ft lower elevation.
I'll swap the air filter (I have a spare on board) and see if that
helps.

That parking lot is pretty clean. You might try running it for a minute with
the filter
removed and see if you get enough air flow to solve the problem.

Kerry,
Thanks ... I just put on a new filter, and the genny is back to
normal. Voltage is up to 127 on my multimeter -- the exhaust is
slightly black -- and _that_ I attribute to the altitude. I must have
encountered more dust along the way than I thought.

Powertech Generator --engine not running right. - davidkerryedwards - 06-05-2007 15:03
Glad it's fixed. It's a little late to be telling you this now, but the town of
Golden has a nice
RV park along Clear Creek just west of you. It's not listed in any guidebook
that I've seen
but it's in town, right on the creek at the Whitewater Park adjacent to a very
nice recreation
center/park with a bike path that runs right along the creek. Just a short walk
to Coors
and it's tour.

Pete, the electric fan that cools the radiator creates major dust.
Good filters choak up fast. when you run a diesel rich for a period
of time, it is always a good idea to change the oil.

Powertech Generator --engine not running right. - Gregory OConnor - 06-06-2007 00:49
A frenchman with a flamingo posted that the crank case breather on
the powertecs vent too close to the airfilter and the paper element
gets a oily residu which gums up with dust quickly. I plan to take
Randys advice, heed the warning of Petes discovery and vent the
crankcase tube out of the airtight compartment.
