Art, we met in Paso Robles California a few years ago. I have had full knee replacement on both knees back to back. Both very successful. Give me a call and I’ll tell you how to have a successful replacement. Four one seven 830- nine 7 four nine.

Could be a bad sensor but 2 at same times doubtful, I would check and clean all connections on ecm for starters. All grounds would be a good second choice.

We didn’t know what ATF was in the bus when we bought it almost 7 yrs ago. We changed the fluid & filters soon thereafter w/Mobil Delvac 1 Synthetic ATF, an Allison approved TES295 fluid. The tranny holds about 10gals, but you can only get 6 to 7 gals out when doing a fluid filter change. So now, after 2 changes, it should be mostly Mobil Delvac 1 ATF in it.

We took a ATF sample when doing this change and sent it to JG Lubricant Services Houston TX lab for analysis. Again, the results and a ph conversation with Tom Johnson, aka “Mr. Transynd”, indicate there’s nothing to be concerned about. The old fluid and filters were 6+ yrs old w/26k miles. The bus has 94k miles since new.

Our B500 has a 2” sump, so filter is 4” long.

The old Allison filter kit # is 29548987, now superseded by kit # 29558117. I only use Allison brand filters.

The Battery Charger #1 & #2 should be the inverters.

24 Volt Charger is the auxiliary onboard charger for the chassis batteries. You shouldn’t need to have that on unless the chassis batteries are depleted for some reason.

Our coach just sat for seven weeks plugged into 50amp shore power and the chassis charger turned off.

Do you have the original chassis battery charger that Liberty installed? Huge. It’s probably a single stage high amp 24 volt. I’m told when on it just hammers the batteries and isn’t good for them. You need to replace with a modern three stage charger like a Guest/Marinco Charger.

I’m not an electrician either.

Just an FYI

We never put a probe on the inlet side of the turbo, if you fry it or break it off for whatever reason the only place it’s going is thru the turbo.

Well, got the overhead set yesterday, put it all the way back together and took it for a 5 mile test run today. REALLY looking forward to pulling some grades to see how it does. There is a noticeable difference in throttle response and rev time. The new turbo builds boost faster than the old turbo. I didnt realize how bad the turbo lag was until I did this work. Ill try to get some video of the instrument panel when I take it out so you can see the acceleration, temps, etc. So far, Im happy.

While you may be correct about municipal water systems likely protecting the tank we have been in enough situations where we were on a well, including at our home. For the little amount of time it takes to periodically sanitize the system I likely will continue to do so.

[Dave]

I have zero influence with Prevost. It would be nice if did have some but as seated coaches became such a large part of their business motor homes just don’t make enough of their revenues to get their attention.

[Dave]

We use ours quite a lot when on our beach front lot… we turn it on and can see the whole beach in front of us at night… really nice !!

Cheers, Diane

Jimmy,

First I would contact Prevost and have them walk you through your codes. The reason for that is they are a Detroit problem and it could be almost anything, including something better dealt with by Detroit, or Prevost. A check engine light can be a simple sensor ground issue with a code providing some direction on where it might be or it could be something Prevost might be best to deal with such as a failing charge air cooler or hose within the system.

The alternator may or may not have anything to do with the check engine light. I am not familiar with how Marathon has your alternators set up, but I suspect one is dedicated to the house and one the chassis and voltages that go out of range on the engine are going to create a check engine light, but you can read your voltages to determine if chassis (engine) voltage is going up and down. Typically if the chassis voltage is not right you will get a dash warning light however. I would go to Prevost for the alternator issue.

thanks for the offer, but we love our new coach. As you said, you’ve gone to “max” risk on numerous items

We, too, have patio awning risk being equipped with a Girard

IFS, has been with us on the last two coaches, only the 1992 Beaver Bus #34 had solid axle out of the six busses we have owned

we did stay with rivets, but we have two (2) sliderooms. Front slide is 17ft, but our front axle is under 16,660 lbs gvwt

however, we don’t have air bladder slide seal risk. We have internal and external “D” seals

we also have no egr technology to worry about

in our eyes we have the best of both worlds

[Dave]

OK, Jon

i stand corrected about our total generalization. Only the coaches we have personally inspected( panel tapped with finger) had loose panels both “retail coaches” and owned coaches we randomly see

[Dave]

Thanks Jerry. I feel that mine would do the exact same if I had the valves working correctly. Getting on it soon.
