Gerald, it seems that the bugs with the early generation slides were worked at at the service center level because we rarely hear of issues with slides now. When they were first introduced it was common to see several slide coaches at service centers being serviced with slide issues.
All slide coaches will require some maintenance such as slide seal replacement, and if a control fails it is a pricey repair or replacement, but keep in mind that is well compensated for by a much lower initial cost of the coach.
I believe the EGR coaches started with 2004 or 2005.

Bus is tucked away in warm and sunny SW Florida, but we are still stuck in Milwaukee, a white xmas and balmy 17 degrees. A merry xmas and wonderful new year to all.

One of these days I need to learn to read.

Jerry,
After I purchased my bus I had it washed in Spearfish, SD and told the guy, do not put any of that crap on my new tires. Should have stuck around, came back and one of his nit wits did what I asked him not to. It took almost 2 years for crap to come off and made the tires look blotchy. I use 303. Maybe someone put some of that garbage on your tires.

Well Said Mr. Mark.

Dick, not sure if I have a phantom draw, since I have never had an issue with the charging of the chassis batteries, I find it hard to believe that it would come up out of nowhere. But this is a prevost, so nothing is off the table 😉
Will check on the volts on the battery posts and jumper posts, but I will also check the cables to make sure they are good/clean before I pull anything and get new batteries.
Hope it’s an easy fix, not really near anyone convenient to come out and check on it. Kind of in the middle of Jacksonville and Clearwater and really far from ETLC. Haven’t come across any other service companies that know Prevost chassis in the Ocala/Gainsville area.

On my coach, there is one or more relays in the electrical panel outside driver area. I have experienced a failure.

Thanks everyone for the kind words.
I’ve been lurking here for about 2 years trying to soak up some information prior to purchasing a Prevost conversion coach. Thanks to what I learned here, I wouldn’t buy a coach of this vintage without a Prevosr Service DMI. Prior to making an offer on our coach we went to a Prevost Service center and a Marathon location, took a tour and then spent some time talking to Service Managers at both. They both explained the things that they would service and wouldn’t. That was time well spent…in my opinion.
I’m sure we will need some help as we go along.
Thanks again.

In this day also then when the system fails that should of detected and slowed your vehicle people will sue the manufacture or installer for their poor driving….Example of this mentality is HD satellites can be hooked up to stow with ignition key on, well people don’t check that this actually happened. So now the satellite manufacture quit selling the cable to auto stow because people wanting warranty when it failed to stow for whatever reason and they ruined their dish…..Technology has a lot of good things however it also has a lot of things that are taking away from us….

I’m with Jon when it comes to Onstar. I disconnected it for the very same reason.

That’s the kind of thing I’ve been looking for, but haven’t found. I’ll check to see if there are any artifacts left in the coach which might have been used to mount the blue device if a previous owner removed it. Thanks!

I only had a few minutes to mess with this Monday but here is what I have.
The top of what I think is the pressure sensor shows continuity with junction block 20. When I run between the bottom of the sensor with junction block 69 the display on my digital meter fades out. I have not seen that before. Is that because it has voltage on it?
I will be back on this Wednesday morning. It just occurred to me that I can turn off the voltage from the batteries to check the continuity if voltage is a problem.

Sheesh Dick, I think the cheese has finally got the best of you.
I didn’t say any of this…
Tom: Have you thought about rigging up a three-way circuit with an air switch in the shower?
Tom: Now you’ve got me thinking more. I have a Headhunter Mach 5; Jeff installed in December of 2014.
I’ve seen Tom’s solution of putting a temperature controlled solenoid valve on the coolant line entering the water heater to hold the temp down to a reasonable level.

right now i consider myself in the second category. Things like brake relay valves, air bags, ac install and others items have shown me that i need to let a pro do it. I am capable of accomplishing those tasks but, i need the equipment/tools and a location to work on it. Being a fulltimer has its limits.
I have rebuilt my Webasto, completely rebuilt the microphor, did my headlight conversion, switched the interior to LED and accomplished a lot of stuff inside and outside the coach. Under the bus items are off limits for me. I won’t mickey mouse under the coach. I defer to the pros on that stuff.
Maybe one day we’ll settle down and i have a bus barn + all the right tools. In the mean time, i tap the knowledge shared here and on other internet sites and defer to the pros

BIG CORRECTION! I have been giving you faulty information on voltage due to user error. That has caused you to run rabbits for no good reason and I apologize.
The following readings are with good ground.
13V on #1 pin with the key on. This should be 24V. Junction 69 has only 12V with the key on too.
I do show continuity between Junction 69 and the #1 pin on the High Idle switch.
Junction 20 has 24V with the key on.
Pressure sensors:
I can not see any numbers on the wires going to the pressure sensors. The top sensor’s black wire has an 18 or 81 stamped marking but that could be the 18 gauge wire.
With the key off both pressures sensors have 24V on the bottom lug and no voltage on the top lug.
With the key on and the parking brake engaged there is 24V on the bottom lug and 12V on the top lug.
With the key on and the parking brake released the voltage is not changed. It remains 24V on the bottom lug and 12V on the top.
Again, I apologize for the wrong information on voltage. It was completely my fault.
Thank you,
Davy
Also, do the light bulbs on the dash of my vintage twist out, pull out or what? Even my wife’s skinny fingers can not remove it.
