I do want to make sure we cover as many coaches as possiuble and I see a mix of coaches. Help me by making sure your signature includes the year, model and converter. I don’t want to overlook any coaches, and if necessary we might have multiple coaches up in the air because as they evolve there are differences.

Yeah Andy, would be helpful to have a list of napa stores as none around me (60 miles) will honor them. Not corporate stores they say.

Do the air bags and Norgrens first so if there are any leaks they will show up and can be corrected. Brake issues will show up on the pre-trip test.

Have a Jake. When towing the trailer(3axle 30′ Stacker) I think I stop faster than when not. In fact, I prefer going down the mountain with a trailer than without, because I can use the trailer brakes to pull me back a little. Geo.

I have to make some assumptions and the answer is based on those.
I assume you have a large alternator mounted at the rear of the engine, gear driven, that supplies charging current to the chassis batteries when the bus is running.
I assume the regulator shown is for the second alternator which supplies charging current to the house.
Or vice-versa. It really doesn;t matter if I have it reversed for the answer to be accurate, but you need to know which is which, if for no other reason than to be able to trouble shoot issues.
Your chassis batteries and your house batteries should be separate from one another electrically. In other words my final assumption is your converter did not use one set of batteries for the entire coach, both house and chassis.
Start the coach and put it on high idle. Measure the voltage at the house batteries. If the house is a 12 volt system the voltage should be 13.6 to 14.2 volts. If a 24 volt house system it should be 27.2 to 28.4 volts.
Measure the coach batteries. The coach will have a 24 volt system and it should read around 27.7.
Turn off the coach and wait a few minutes. About the time it takes to drink a coffee. Measure the house. It should read around 12.6 to 12.8 volts assuming you have no loads such as lights etc.
Measure the coach batteries. The voltage should read around 25.4 volts.
If there is no difference between the battery voltage when the bus engine is running and the voltage when it is not running it is probable the charging system for that set of batteries is not functioning. If that is tru diagnosing the problem is the next step.
Usually that vintage coach was built with converters which were used for charging and later models got inverter / chargers. To try to add an issue into this question can get difficult because not all “upgrades” were done properly.

Ditto. The first thing I would do is insude the fan clutch is functioning. At that temperature the fan clutch should be locked up. Verify that is the case.
If you lock the fan, take it for a test drive. At that point you will see the coolant temps cycling at the thermostat operating temps as stated above. With the fan clutch locked if you still are seeing those high temps the problem is likely a bad thermostat or radiator. If it is either of the two my guess would be the radiator.

I should note that Tom’s Liberty had a non standard bay configuration. If you have a chassis battery charger look over the chassis batteries on the ceiling. That may be where your charger is located.
You also should have a circuit breaker labeled 24 volt charger in the electrical panel. If so make sure that is off.

First to Paul. Definitely the first was more fun. At least I knew what I was trying to do, even if it didn’t work out. To Tom, I was so proud of myself when I found a way to put a pin on a map using my PC, now I assume from your response that I pinned the wrong map (kind of like I pinned the wrong girl). I’m the guy you had to help post pictures of my coach in my for sale ad. Definitely not a computer wiz. So how do I pin a PC map?

Looks to me like that tire has water in it like we did with orchard tractors to give them better traction. They always spit a bit around the rim…. Tire installation lubricant, just soapy water isn’t it? That should disappear in a few miles….not months. And Jon, there is some kind of trick tire dressing (other than my used car lot sample above) that I have heard folks raving about, supposed to have UV protection in it, personally do not no any more….may be called 303?

It could take easily 3 – 4 hours to charge. Don’t shut down the gen until it gets to float.

OK, kidding aside Tom’s idea is a good one. Apart from the show and tell aspects along with bragging about how copper pipes are prettier than white plastic, I think we can all benefit from having an opportunity to look at the bays and inner workings of the various conversions.
There is no better way to learn about a coach than to understand how the converter put them together. It will be a good opportunity to look how all the converters do things, ask questions, and get a better understanding of your coach. Those that know their coaches well will help those relatively new by helping them understand how things work, and how to access and repair things.
For anyone planning on buying a coach this will be a perfect opportunity to see and understand how the different conversions are built and layed out while talking to owners who know both the good points and the not so good.

Jeff,
The one showing voltage was the gen, he had it running. Did you lose your glasses?
-
Don’t know if I will get to it before OKC, but the next part swap out I guess is the wet tank to governor line. I’ve always prefered to throw new parts at my stuff rather than pay for labor. Thanks everyone, see you soon.

All,
I appreciate all of the responses regarding the dishwasher question.

Those of you that have signed up, thank you…
Those who haven’t, ya better get on the list soon.
