You have something stuck in the blades if it doesn't turn freely. Actually it is very easy to remove the pump. I think the small hose has a clamp and slips off and the electrical unplugs. Remove the screw from the bottom bracket and rotate the pump off just like you rotate the 4" cap off. You can then look inside to see if you can rotate back & forth until you can get the item out.
17  Main Forum / General Discussion / A/C Fan runs when furnace is turned on on: November 03, 2013, 09:25:30 pm
I'm not sure what my wife did but now when I hit thermostat 3 times to run the furnace, the roof air fan runs. The furnace does come on and responds to the thermostat setting but the only way to turn the roof fan off is to turn the thermostat off or turn off circuit breaker #4 (Roof A/C).
It must be a control system failure of some sort, any ideas of what to check further or how to go back to normal?

Can you rotate it 360o with the screw driver. Do it in both directions and try again.

Of course, Ethanol has a lower heating value. So when they add it you get less gas mileage.

I used to have a 2551 on a E350 chassis. In 30,000 miles I averaged 10 mpg.

Now with my 2552 on a E450 chassis I get 9 mpg, which was predictable from the change in rear end gear ratio.

I've broken about 7 so far. I got 8 free from Carol. They are cheap made in China latches and easily break the moveable part. They are made by brdsupply.com . If they won't give me any more free, I found a source on-line that claims they have USA made replacements that don't break.

You know what causes it. PC has some unprotected screws right in that area and if you pull the hose it punches a hole into the hose.
Can't remember how I fixed it.

In an old RV I owned with a Kohler genset in the mid 90's my carburetor plugged up and would not start because I did not run it at least once a month.
I pulled the carburetor and had a small engine company throw it in an ultrasonic cleaner. It worked fine and after that I always run my generator once a month.
23  Main Forum / General Discussion / Re: "TOW Haul" feature as shown on dash and trans light keeps coming on. on: October 12, 2013, 08:51:01 am
1. With light on is it actually in tow haul mode. Easy to tell difference because of shift points. I had the problem and it was due to animal chewing on the wiring.
2. The free checks at auto stores, do NOT do transmission codes.

I checked my 2010 2551 today and found the following.  The three circuit breakers shown going to the generator in your schematic go to the Sani-Con pump (20A), the slide motor (20A), and the third is the charging line from the engine battery/alternator (40A).

Thanks a lot, I revised the drawing. My unit has 3 - 20a breakers & 1 - 40a that I showed going to engine battery, so I assume the third goes to the Generator starter.

I traced the wiring and drew them up.

I thought that those 3 wires that go through the breakers were for the Generator controls, but you may be right, they could go to the slide and macerator. I'll have to disconnect and see where they actually go. The same setup was in my 2006 2551. Maybe only one goes to the Generator.

I'm sure the electrical systems are identical in 2011-13. I just said 2552 since that is what I have. The 2008 models had different Inverters & Converters but basically the same system with 12v batteries.

Here is the standard PC power system wiring for the last few years.



Where you add an Energy Management System



System with solar arrays and charge monitor.

I would like to clarify the battery charging for our readers.
The Inverter DOES NOT charge the batteries, it is XADC-60 Converter that outputs the DC power and charges the batteries.

The problem with charging batteries when hooked to 110v power or using the generator is that the converter is not set up to fully charge your batteries.
The converter floats at 13.5 volts and charges max at 14.2 volts. The battery manufacturers recommend 14.8 volts.
The result for most RV'rs is that you probably only get your batteries charged to 80% of capacity. So they still work but they discharge quicker than they should.

When you use a solar array and a good charge controller you find the float set up at 13,7 volts and the max at 14.9 volts. The batteries get fully charged.

I think I will post a few electrical system schematics of PC's 110v & DC power systems on a separate post to clarify how they are wired.

The reason you do not need an anode is this is an Aluminum hot water tank, not steel. exactly!

I've installed this same unit in my last 2 PC's.
For people just ordering a new PC, you can supply the unit to PC and they will install it for you free.
I put the display right next to the door so I can pop my head in to see what's going on quickly.
They also installed my solar array charge controller, shown just below the Progressive display.


Does it work, you bet. Don't leave home without it.

It will not allow you to plug into any bad power source and it will save the expensive items in your RV that will fail with high/low voltage or power surges.
The little card next to it show all the error codes that could be displayed.

But most of all if you travel to Mexico, as we do, you will find their RV park wiring to be very bad and the unit is mandatory.
