PROBLEM;
Powertech Generator won't start

I tried every switch to turn it on (there are several) including the one on the side of the generator thinking I might have a bad switch but none of them worked. I clicked the reset button on and off, still no results.

I tried the battery switch to use the engine batteries (I know those are in great shape) instead of the coach batteries, still nothing. I took off the cables from the battery and cleaned them very well but did not try to start it at that point (figured I'd have more time the next day if the problem continued)

Then I tried the switch on the dash again after runnning down the road awhile the next day and heard the generator come on. Weird, but I thought it might just be a voltage problem and with my coach batteries charged back up from the alternator (if indeed that was the problem) I'd be fine. (always an optimist)

Well, after getting parked I tried it again. Won't start.

Maybe its a ground problem but I don't see where the ground is attached to that Kubota engine. Does anyone know where that attaches or have any other suggestions?

Thanks

This is the generator stop/shutoff relay. He said it was designed originally to prevent someone (like grandkids) from trying to start the generator while it was already running. He said those relays tended to quit after awhile so they don't even use them anymore. Attached to it are 2 blue wires, one black wire and one white wire. He told me to take off the two blue wires, cut off the connector ends and butt splice them together, effectively bypassing that relay.

Preheated the generator, it cranks up no problem.

Excellent! Even dummies can fix some things.

Now back to installing the connector I bought for the heater hose that was leaking. I sure hope that puddle I'll have to lay in dries out before this afternoon.

I have seen a larger air filter used on the 15KW Powertech. Anyone know the number of the larger filter?

Thomas last Dec when they put a new genny in my 99 they put on a newer style cartridge type filter system. Give PowerTec a call. They have them in stock and the replacement filters as well

Well, if you compare it to a car, 100 hours at an average of 40 mph is 4,000 miles, and many of us change oil at 3,000 miles. However, the Kubota has twice the oil capacity as many engines that size, so maybe more than 100 hours. I hear the big thing is to change the oil at least every year to get the water and acids out.

I'm not sure if Stephen has these but I have one of the ones that Randy sold, the Dupree Filter and it is significantly larger.

I talked to the owner of Power tech at a RIV and I questioned the 100 hour service interval. He basically said how often depends on the enviroment it is run. In a dusty dirty enviroment, then you need to change it more often than running in a clean enviroment such as a paved parking lot.

I change my oil and all my filters (except air) at 150 hours. My air filter I change every year or so, depending on how dirty it looks. We normally do not operate our generators in a dirty dusty enviroment such as a plowed field.

I had a friend who had generator problems at a football game. It seems it had been over 3 years since he changed anything. I had a spare air filter and that fixed him up. It was another year before his generator was seviced. It was only serviced then, because I called the mechanic and asked him to. As amazing as it was, his oil level was good and the genset ran very good. I estimate that his generator ran between 700 and 800 hours between oil and filter changes. However, he never did any maintance on any thing until it quit working.

That is a tribute to Kabota and Powertech and their durability in the face of non-existant maintance. With this in mind, oil and filters are cheap insurance.

Change your oil and filters every 150 to 200 hours (or once per year) when run in a clean enviroment and change your air filter every year.

At the last FMCA Perry rally, Power Tech's Mickey Smith came over to look at the genset and gave me a lot of pointers. One was to change out the air filter for a Donaldson which has a shroud around it kind of like a muffler. Yup, made it a lot quieter. Amazing how much of the noise is from the intake. Pictures below.

The whole assembly is Donaldson P/N Go52510. You can even duct the intake to a better spot in your genset cabinet.
The replacement filter cartridge is Donaldson P181050, or the long life washable version P182050. The NAPA cartridge is NAPA 2276, about $32.00. Pricey, but much superior.

The other pointer was to install a low level cutout switch, since he said if the coolant level goes down, the high temp switch is not in collant and will not shut down the engine. I bought one, but have not installed it yet.

One very important item:

Coolant over temperature switch (shuts down engine for antifreeze high temp)
Powertech #05STKUB03
Kubota #19498-83040 (110C)
Denso #110 OS 23

Ron, what did you get for the high temp switch?

Is it even possible to get the 15kw to full load with the regular coach equipment?

Does anyone know a good estimate of what percentage a normal summer day with 3 A/C's, battery chargers, and a tv would be pulling?
