Hi Dick…photos I took of ours. Pretty simple release, might check the release mech in the engine bay to see that the press fit/weld to the shaft thru the bulkhead hasn’t failed. I suppose it could fail on either side though. I’d think it would be pretty hard to jam, but stranger stuff has happened…

Hi Pres,
I thank you and Les. I have my Acct with Prevost and do carry the coach info, service manual, parts manual…

Little stuff, air fittings, pieces of air and other hose and pex sections and such.

Les…I learned that 30 yrs ago with my Bluebird!!, and I thought those items were specific to the birds!!

Yes I had a similar experience at American Fleet Labor Day week. Danny, their customer service person, told me they had never used Rotella Ultra ELC before (I brought my own), and some customers who had just used ELC were going back to the traditional chemistry, 2 year stuff because it is a bit cheaper, readily available, and lower risk of degradation. Probably a good strategy, especially for those who have their service done for them.

If the fan engages with the relays removed then it most likely is a short to ground from one of the two ground wires from the fan clutch assembly. It also could be that the wire is shorted internally in the fan clutch,

You are correct in that there is no activation of the fan clutch on OTR A/C equipped shells.

Look at the relay bases for the two relays and see if one of the wires may have come loose from the base and has dropped down and is shorted there.

Is the fan in low or high speed when you start it without the relays? Depending on the speed you can look at the relay base and ground wire back to the fan clutch assembly for that speed. See what you can find there.

Thank you.

I believe it is the low speed fan that is on. I could easily be wrong, since it seems to be a habit with me, but I think it is low speed. Is relay 78 low speed? How are the wires attached to the relay base?

With the wires bundled and running along beneath the relays, it is difficult to see much there. I will try to check the relay wires first then move to the fan and work my way back. If I get to the compartment with the relays and have not found the problem, I may have to un-bundle some of the wires.

I never thought of the short being internally in the fan clutch until my Dad mentioned that as a possibility. Thank you for confirming that possibility.

I drove 400 miles Saturday evening and Sunday morning. All remains the same.

Thanks again for your help.

Les, It may seem like I was kidding about the selection being a lot easier than learning the coach………..I wasn’t.

We Prevost owners never get knowledge of our coaches until just after we needed it.

I know Jon’s story is true because I was behind Tom and could hear both Jon and Tom clearly. I guess I was driving into those radio waves, or hearing them as they bounced along the ground after Jon ran off and left them.

Les, I can bring the padding to put around the chair so passing out won’t trigger fulfillment of the high deductible supplemental policy.

My guess is you can rule out the thermostats otherwise with a fan on 100% of the time the engine will take forever to warm up it it ever does.

I do not know where the fan clutch gets its signal to engage, whether it is a sensor or if a sensor sends a temperature value to DDEC and DDEC is what controls fan engagement.

The problem does need to be fixed and the repair cost will come back to you in fuel savings. It takes engine power to spin the fan and I have heard that it can use as much as 30 HP. Additionally the engine is more efficient at higher temps so just averaging 200 degrees instead of 185 for example is more efficient use of fuel.

I will reach out to Bill Jensen and see if he can help.

John, there is a large mall and conference center at I-40 with Wendover Avenue. If you are just looking for overnight parking you might look there. I don’t remember the name of the mall but the convention center is Koury Convention Center. Maybe look them up on the internet and ask management about accomodations.

[Davy]

Could that affect both the coolant temp gauge and the transmission temp gauge? They are tracking closely together. I believe it is showing me the real temperature.

I am open to the possibility.

Davy

[Davy]

Davy, just a guess, how bout the gauge, ground, sending unit?

Many years ago, my exhaust temp gauge began to show lower temps gradually, and now shows no temp. Put in a new pyrometer – no help. Still don’t know what’s up.

So I don’t know where our gauge grounds are located.

My understanding was that all the recent Marathon bunk coaches were coming standard with this or a similar feature…. Not sure about the add on drapes…

I’m the second owner of this coach and it’s my understanding the original owner was one of the few who ordered the drapes vs. the folding doors. As you can see in video, I’m one who prefers the drapes vs the doors as it opens up the bunks.

I like all the disable features… I don’t recall seeing that on the model I saw…

This was a requirement I made when ordering this mod. Marathon did a commendable job figuring out how to implement it into the bunk and control panel. I don’t believe they had done this before in this manner.

We love our Bunk coach… but we always have the three kids so both bunks are full… but when they get older and we travel just the two of use… might be a nice mod for us. What I really want is a nice office setup… still thinking thru it…

Florida Coach has my favorite office mod. They typically place two sets of three bunks across the aisle from each other and one that I saw had one of the bunk banks removed and used the space for a three foot long desk. They placed a washer/dryer stack in the adjacent space. It works for their coaches as they have the vertical window in that space and it goes very well with the desk.

Journeyman, I called Elgin and I had them send me the diagram from the part that they sell… for a lot more money # 560030 and in there it shows how to jump it so I should be ok with that even if these other ones on ebay don’t have the paper work.

Thanks for the info!
