Hi Dick,

Thanks for the warning and sharing your experience.  I agree with Ron, please provide more details and pictures.  What failed, the bracket, car frame, bolts, welds?

I tow a Jeep Wrangler and am very interested.

Thanks, Bob

Got the generator fixed at Cummins Northwest in Missoula, Mt today.  They quickly determined that the voltage regulator in the controller was defective, the controller shut down the generator because the voltage was too high.  They had a new controller in stock and had it repaired quickly.  Great service from Cummins Northwest in Missoula, Mt.

Hi Ron,

The gas level was the first thing Bob at Phoenix mentioned, the tank was nearly full.  Also, I made sure the oil level was ok since the generator will shut down if the oil pressure is low.

Hopefully it can get fixed when we get to Missoula next week, since we have 5 more weeks to go!

Paula,
I have a 2010 2551/S, and yes the pump is under the passenger side bed with the water tank.  My pump was very noisy and cycled a lot.  The pump was attached directly to the hard plastic water line, and as Terrel mentioned, Shurflo directions strongly recommend against that.

I installed the Shurflo accumulator ($60), it is smaller than the one Ron installed but that is what would fit in the space.  I also installed a strainer at the pump inlet as recommended by Shurflo.  Also, I adjusted the pump shut off point using the screw in the end of the pump according to the instructions.  The most important thing is that the pump is no longer directly attached to the hard plastic water line and the difference in noise level is amazing, can hardly hear it now.  With the accumulator tank and adjusting the pump, there is no more cycling, the pump runs very smoothly.

Hopefully you can see the installation in the attached picture. The pump was located where the accumulator now is and attached to the hard water line hidden under the black ABS line.  There is now flexible line between the pump and accumulator tank and a strainer at the pump inlet hidden under the relay in the picture.

Hope this helps, Bob

Hi all,

Just started a 6 week trip in 2010 2551S last Wednesday.  First night near Elko, NV we turned on the generator to run the air cond, dry camping.  It ran fine for 30 minutes and then died.  It starts and runs slow for about 5 seconds and dies.  It shows a fault code #12 "controller unable to maintain rated voltage".  There are only 2.8 hours on the generator.

I called Phoenix next day, determined it wasn't anything simple and said to find authorized Cummins/Onan dealer for help.  We will be in Missoula, Mt next week and will get to the authorized full service distributor there to see what is going on.

Anyone have any experience with this problem?

Thanks, Bob

I have discovered that the battery disconnect light is deceiving.  On my 2010 2551 model, the light stays on even with the batterys disconnected when on generator or shore power.  I have confirmed this by testing at the relay under the passenger bed.  The battery side of the relay is wired to the inverter, engine charge line, macerator pump, and slide motor.  The other side of the relay is wired to the converter/charger and all 12v circuits in the converter panel.  The relay is a latching style relay that stays in either the closed or open position without voltage.  It is operated by the rocker switch on the disconnect panel at the door.  The red led indicator light on the disconnect panel is wired to the converter/charger side of the relay; so when the converter/charger is powerd by shore or generator, the 12v circuits and the indicator light are powered even when the relay is open and the batterys disconnected.  When there is no shore or generator, there is no 12v power to the convertor/charger side of the relay and the indicator light goes out when the relay is opened to disconnect the battery from the 12v cicuits in the conveter/charger panel.

You can confirm this by watching the inverter voltage when you open and close the relay while on shore or generator power.  If the battery is not fully charged you will see the voltage jump up to a higher charging level when the relay is closed and drop back when open.  On the disconnect panel, "use" is closed and "store" is open.  When I am plugged in to shore power while stored in my garage for an extended period, I will disconnect the batterys from the converter/charger to keep from over charging, may not be necessary with the 3 stage charger but I do it just to be safe.  Since it is not obvious that the relay is open because the light is still on, I will occasionally push the store side of the switch just to be sure.

I hope this makes some sense, I may have rambled on too much here.

The AC and microwave do not run off the inverter; however, they should turn on with the generator running unless the main or individual breakers are off -- have you checked the breakers?

As for the inverter readings, sounds like the battery disconnect switch is off.  When the battery disconnect is off or disconnected, the engine can still charge the batteries but the generator or shore power cannot.  This is actually a good thing in that you can keep the batteries from overcharging while on shore power,  although not a serious issue with the three stage converter/charger.  The inverter is reading the battery voltage with the battery disconnect switch on or off.  Try this experiment, with the generator running or on shore power, watch the inverter voltage reading as you turn the battery disconnect switch on and off, if the battery is low at say 11.8, then it will jump up to a higher charging voltage when the switch is connected or on.

Hope this helps,
Bob

Hi Glenn,

We got what we could from this forum and the PC website.  We new which model we wanted, but we needed to see it in person.  We checked with the only PC dealer in the west in Tempe, AZ and they had the model we were interested in.  We live in California and on our winter trip to Arizona this year we went by the dealer and checked it out.  We spent a few days in an RV park nearby and thoroughly checked out the new PC at the dealer, they were very patient with us.  We ended up ordering our 2010 2551 (with slide) through the dealer and picked it up two months later at the dealer.

I also saw that it was just a slip connection and put a hose clamp on it.  Soon after, I was dumping and noticed that when I turned on the macerator pump the hose started to get longer.  I shut the pump off and realized that I had forgot to take the cap off the plastic end piece and the pressure was making the hose grow.  Good thing for the clamp or there would have been a mess.  Needless to say, I now remember to take the cap off.

Ummmm, she didn't say it was a 2010, she said it was the new model 2910.  Good job Aimee and thanks for the photos.

What RV year and inverter model do you have, maybe my 2010 RV with Xantrex XM 1800 operates different from yours.

On mine, when plugged in to 110, the 110 passes through to the items you described with the inverter on or off at the control panel on the wall.  Also, the battery switch has no effect on the inverter passing through the 110.

Are you plugged into shore power?  On shore power, the 110 volts passes through the inverter to the items you described whether the inverter is on or off.

If not on shore power then the inverter needs to be on to provide 110 volts (from the batteries) to those items.  When the inverter is providing the 110 volts from the battery (not on shore power) the inverter will shut down if the battery voltage gets too low or if the output load is above its limits.

We purchased a new 2551 in April with the new sofa/air bed.  When we were shopping for the RV, we had an opportunity to sit in one with the old electric fold-out sofa and the new sofa/air bed.  We found that the new sofa is much more comfortable to sit on and it sticks out 6 or 8 inches less than the old one when in the sofa position, a big difference considering the room available.

We slept on the air bed once and it is ok - not great, but it is for the grandkids and they think it is great.  We are really happy with the new one for sitting comfort and more floor space.

Hope this helps,
Bob

Maybe your 2551 is 10'-1" if you had it empty, no gear, no water, just a couple gallons of gas in the tank, and then with the max tire pressure of 85psi.  Kind-of-a worst case condition.  Who really knows.

I always store ours in the garage with a full tank of gas & gear, but no water, and 65/70 psi in the tires.

Good point Ron, My 2551 has full gas, no water, 1/2 gear, 80/75 psi tire pressure when measured.  Maybe the gas and 1/2 gear load accounts for lower height.  I should check again someday when conditions would give maximum height just to know.

Hi Mary,

I have a new 2551 that we picked up in April.  I just went out to the garage and measured the height.  It measures 9'-11.5" to the top of the AC, the AC is 11" tall.  I am surprised that it is lower than the spec height of 10'-1", maybe that is for the standard AC and now they are installing the low profile AC, you might ask Kermit about that.

If the Dish is 15" as you indicated, then the top of the dish would be 4" taller than the AC which would result in a height of 10'-3.5" on my 2551.  Keep in mind that the roof slopes down to the front a couple of inches so you would need to account for the location of the dish relative to the AC.

I also store my PC in the garage and the opening is a nominal 10' wide x 12' tall, plenty of room for the PC.

Hope this helps,
Bob
