The sending unit is no more than a variable resister with one end connected to ground through the sensing unit and the there end connected to the insulated terminal on the sending unit which is connected to the "S" terminal on the analogue gauge.

The only way that the analogue gauge could read backward would be if the polarity would have to been reversed on the gauge,  This could have happen when they were troubleshooting the problem.

Also make sure that the pointer on analogue gauge is position on the correct side of the mechanical stop on the gauge face. When I was changing the oil pressure sending unit on my coach I had the pointer jump to the wrong side of the mechanical stop and the pointer couldn't move.  I had to drill a small hole in the back of the instrument and flip the pointer on the opposite of the mechanical stop.

When I checked with Webb a couple of years ago they informed me that the 65555B was no longer in production and they didn't have an alternative drum.

Mine wasn't tunable do to heat cracks and deep groove that exceeded max. ID.

Attached is a spreadsheet for the dimensions for a Webb 65555B drum and the one I installed on my Holiday Rambler Endeavor.

The bolt hole diameter is a bit larger however spacers are available.

Price for drum was $129 and free freight  from FIND IT PARTS on line

Spacer were about $40, can't remember where I purchased them, it was on line

Hope this will help.

Thanks to all.  And yes, once it has run a minute or two the smoke clears.  Only smokes at start up.  Yeah, three glow plugs were replaced, I called them coils.  It could well be the case that the shop that replaced the glow plugs would have liked to have sold me a new gen set for $12k plus labor.  My feeling is  that the diesel engine should run for many more thousands of hours.  In cold weather it could well be the case that the engine cranks before the glow plugs have had a chance to get hot.  

Very good news, that leaves a blank check to pay for 8 new tires.  Yay!!  Just need to arrange a trip to a state with no sales tax.  Oregon is not too far away.

Woody Miller

Point S in Astoria OR. is a good place to buy your new tires. 

Jim

If you only issue is a little smoke on startup and it's not using oil you should be good to go.

I would have a compression check and injectors cleaned before I would be thinking about an overhaul.

Currently camping and hooked up to a 50A service.  My charging panel had  "fault" red light.  I checked all breakers and inverters and didnt find anything tripped.  My panel is showing "bulk" charging, then interment red fault, then charging.  My panel will show batteries charged "good", then "fair".  I checked with hand unit and read 28v in parallel.  This is 2nd campground, first one we had no issues.  I have a Magnum ME2012 unit.  Any suggestions? Leaving tomorrow from Arkansas to NM.

Reading 24 volts with batteries in parallel is not normal,  If you have the manual for your ME2012 there is a trouble shooting section that may help you identify your problem.

The REV group will provide you with a BUILD SHEET for specific vehicle if you provide them the VIN number for that vehicle.

The inverter provided 120v AC to dedicated circuits when shore power or generator sources are unavailable. 

Many electronic products will not perform properly on inverters that produce a modified sine wave output such as your inverter/charger.

Most any local sheetmetal should be able tofabricate a basement storage door and body shop will be able to paint.

Most likely your problem is the pressure switch that is located on the Parking Brake Valve.  It can be found directly below the knob that applies and releases parking brake.  This a common failure and they are readily available at any parts store that carry long hauls commercial truck parts.

Zingman 64 has stated the roller rotates and the fabric gets loose.

Jim

Thanks for the clarification,

Most likely one gas struts has failed and remaining one doesn't provide capability to extend the awning. It could also be it just stuck and need a little assistance to manually pulling from the top when trying to extend it.

Once you get it extended you will be able to disconnect one end of one gas struts to determine if is good, you will have to check each strut independently.

Hope this helps to solve your problem.

The awning on my 07 Cayman XL spins when the extend switch is pressed but it does not extend out.   It seems like it is hung up somehow.   Has anyone had this type of issue? 

Please clarify "SPINS" does this mean that the roller rotates and it doesn't extend or does it mean that you hear it running and no movement of the roller.

Ji,

I damages one of my basement doors, I took it to a sheet metal shop and they made one, He was able the damaged one as a sample of required material and design.  Took it to a body shop for the painting. Total coast around $1500,

Jim

Glad you resolved the problem.  It may be frustrating at times but is rewarding when you fix the problem.

I just don't realize why in all my years and miles, I never had any problem or indication.

I can see this, but with my Big Boy system, I don't believe I can force the batteries apart?  I guess I will try to turn off the charger in the future, I am still puzzled why this all worked fine for years and years.

My coach came with the BIG BOY but it would only combine the coach and chassis battery banks when you manually presses the switch on the dash.  The coach batteries didn't get any charging when driving down the road unless you had you generator running to supply power to the inverter/charger.

I never had the problem until I replaces the BIG BOY with an ACR,

I have been having a few issues with my alternator, replaced it and the new one lasted less than 2000 miles.  It was replaced under warranty, but the alternator guy said he felt there might be something wrong with my coach that caused the failure.  I told him the original alternator was good for 160,000 miles before it quit, and didn't think there was anything wrong with my coach.  I saw your comment and wondered about it, I have always run the generator anytime it is hot to run my AC's and have never turned the charger off.  I have never had a problem until now, but I am not sure I even have a problem and wonder if it is as simple as the new alternator was bad??  Can you elaborate on your comment please?  Thank you.

One our coach (04 Holiday Rambler Endeavor) the alternator trouble WARNING light will come on.  When you have both charging devices (chassis alternator and coach inverter/charger in the charge mode) connected to a common battery the voltage regulator of the two charging circuits are not designed for this configuration.  

I replaced the gasket on my neighbors 5th wheeler, it was a pretty simple job,  His came with the large rectangular piece and a 6" strip of the same material.  I had to cut the strip into 4 square pieces to place where the hold down bolts penetrate the roof that are located outside the parameter of the main gasket.

He just ordered his from Amazon, I think it was around $25.

Thanks Jim B for this valuable info. Do you think brother in law may know where his lift pump may be? Side of engine or tank?   Inline fuse or in fuse block?  Has he dealt with this same issue?

Pushing fuel is easier than pulling so may have moved pump to tank. Monaco built their own chassis tho, so bet Cummins came in a box?  Thanks Greg  W

Actually I have 2 brother-in-laws with coaches that have the 5.9 ISB,  The one with a freight liner chassis (1999 freightliner chassis  has the fuel pump is mounted by the ECM and he got towed in twice because of fuel problems (low voltage to fuel pump) His fuse is in battery compartment was found corroded. 

The other one just purchased his (04 Roasmaster chassis) and has had no problem and hasn't had need  to locate fuel pump, he did look for fuse location and he couldn't find in manuals, manual did state that additional fuses were located in battery compartment. He did locate several in battery compartment and he believes they are engine related, because one was clearly identified as ECM, other ones were not readable.

Thanks guys and RIP Bill D,

Where is the lift pump found on pass side? Doesnt seem to be behind ecm cooling plates as have read? Great news that same as dodge in those years. 

Fuse box in battery box very vague! Ideas on fuse and relay locations? 

Thanks Ray and rip Bill D,   glad to hear may not be dropping tank. Haha. 

Where is your lift pump found on pass side?  Doesnt look like theres a pump behind the ECM cooling plates and cant hear anything running?

Can only find pump # 3964407 pressure pump on pass. m

Thanks and sorry for redundant posts, but big fingers on little phone. Haha 

 

The part # that you listed is the hi pressure pump. You could  start from the fuel tank and follow the fuel line to the engine to see if you can find the electric pump.  Since your rig is 04 I'm still thinking that you will find it in the take, my reasoning is based that by this time that's were Dodge Rams were placing them.

The fuel pump location may be a mystery. The chassis manufactures deliver them to the RV manufacturer as a drive-able unit, I know the fuse on my brother-in-laws 04 Holiday Rambler with the same engine is located in the battery compartment and they are poorly labeled and the wiring is a rats nest,

Never heard of a Monaco with a fuel pump in the tank.    Monaco used an elect lift pump, mine is mounted on the engine ( pass side ).   My lift pump runs for about 30 sec,  after that the high pressure injection pump sucks the fuel all the way from the tank . Both pumps use suction that is why you have vacuum at the filters.                      I have read that the ISB lift pump runs all the time.                                                      

 

You are correct, the ISB electric fuel pump run continuously and is the only low pressure fuel pump.  The fuel system is the same as use on like years of the Dodge Ram trucks.

Thanks Jim, on my 04 ISB 300 cummins it starts instantly and sounds fine even tho 0 fuel pressure at filter head.  Does have 15 inches of vacuum pressure tho. How can engine even start if electric pump is down yet dont hear a sound when key on? Real head scratcher!  

In 04 could electric pump still be on drivers side of engine rather than intank.? Drivers side of engine has turbo, oil filter and alternator.

Followed fuel lines along frame and see nothing?  

Today we tapped into the top of the fuel filter head and installed a fuel line to a boat fuel can to bypass the fuel system.   Fired right up and no 25 15 fuel pressure code.  Great test drive, good power and most importantly, no stumbling or lurching!  

So high pressure pump is good.  There is an air leak or partial blockage in the fuel line somewhere that we bypassed, or an intank electric pump has failed and fuel system starves for fuel under a load even tho engine starts and idles?

Really hope someone here can help wade thru this problem between the ISB 300 Cummins and an 04 Monaco. 

Did Monaco put a pump in tank but show nothing in manual ,and altho Cummins claims there's an electric lift pump that shuts off after 30 seconds we can't see or hear anything and no fuel pressure, yet runs!?!?

How about it Bill D or others with good knowledge of  Cummins and Monacos systems? Is there a secret electric pump in the tank? Thanks 

If I were a betting man, i say the fuel pump was in the tank.  you should be able to trace the wiring to the top of the the fuel tank. If the pump is in the tank you should find several wires going in the tank.

I lead you wrong on the location of the fuel pump is on the engine, it would be on the opposite of the exhaust and turbo. I was think of location in a Dodge Ram.  Before I was too eager to drop the tank you need to locate the fuse for the fuel pump,  On my 04 Holiday Rambler with an 8.3 ISC Cummins, it't located in the battery compartment. In my rig there are in-line fuses and they aren't very well labeled.

Jim B, thanks for the reply, would you know the range of years for engine mounted pumps versus frame or intank lumps, or a source that might?  Strange that my 400 page manual only dicusses the two fuel filters and the complex sending unit in the tank?   No mention of  any lift or transfer pump even tho doesnt appear to be one on the engine. If was on the engine would make sense that Cummins all the help I need. Thanks

The 12 valve engines had mechanical fuel pumps.  I believe all of the 24 valve engines have electric fuel pumps.  The first 24 valve engines were seen in motor homes around the 1999 model year. The electric pumps run continuously on these engines, when they completely fail you  are dead in the water.

On the early 24 valve engines the electric fuel pumps were located on drivers side of the engine.
