First, never charge the high side, in fact don’t even open the valve. The gauge will read with the valve closed. Only charge the low side. When you are done the low side will read around 90 lbs, the high side anywhere between 230lbs to 250lbs, it should blow about 40 degrees below the outside temperature. If you cannot get the charge correct it’s because you put liquid the high side. If you just let it sit for a day or two in the off position it might possibly balance itself out. Be patient. Remember; liquid only in the low side. I wish you the best. JM

Are you running the Aqua Hot on diesel?

I don’t push buttons or switches until I know what they are for. Can any of you fine people tell me what the button between the tach and speedometer is for? Thank you in advance. JM

Regarding the mice, you can purchase liquid tape. If you can get to the wires it's much easier than tape. Really check all of the wires closely for continuity, they could have easily chewed through. I have a Corvette that had mice and many chewed wires. I cut and spliced them all, we're talking twenty some wires, everything works now. Wiring back when your coach was made had vegetable based insulation, very tasty to rodents. The pucks are a good idea. Just a suggestion, best of luck.

There is no way to seal a head gasket from the outside (none that I have ever heard of). Is it possible to get Cummins road service to do the repairs on site? It's a big job, just a suggestion. Best of luck.

Did you replace both batteries? I don’t mess with mine anymore, bought a small battery charger and all is good. Best of luck 🍀

Most coaches such as Monaco will use the same wiring harness on all coaches of a particular model. As OhReally said you will find many connectors unused as they are for options that your coach doesn’t have.

Good morning. Still working on the same problem. Found two air tanks in the ceiling of the passenger side compartments. Used dish soap and water in a spray bottle and soaped all of the joints. Wow, looked like a bubble factory! There are several brass swivel 90’s going into the tanks and all were leaking. All but one were fixed by a slight rotation of the swivel fitting, one wouldn’t stop leaking. Found the fitting at NAPA, 1/2”MIP X 5/8” tubing swivel 90. Replaced the 90 all good. Still have leaks but this was a major find. Good luck.

Thank you Larry, The coach was manufactured in Oregon according to the build sheet. I inspected the air bags and found the right rear seeping air, they are all in very bad shape so I have no problem replacing them. I did find the auxiliary air compressor located passenger side front next to the generator. Runs fine but can’t do it’s job due to a stuck check valve. I’ll fix that at home and install a battery charger for the engine batteries. Thank you again. JM

The engine batteries charge fine when the engine is running. I have leaking air bags and have to start the coach every couple of days to recharge the air. I’m having all air bags replaced next week. I think I wasn’t running it long enough to charge the batteries. The owners manual says there is an engine battery charger on the curb side in the black/gray tank compartment but I didn’t find one. I’m currently shutting off the disconnect on the engine batteries in case there’s a draw. I’ll install a charger when I get home. Thanks to everyone for your comments 🇺🇸

The only dumb question is the one that was never asked, so here goes. This is our first Monaco, 2005 Beaver Huntington 38’. Question; are the engine batteries charging while we are plugged in to shore power? Thank you in advance.

Phoenix AZ today $4.50 to $4.90 🤬

I would find out where the switch or sensor is that controls the warning light. Research the problem and correct it. Warning lights are there for a reason. Good luck.

Howdy. I operate my slides like coaches with hydraulic jacks, “Never open the slides when jacks are up”. I always level our coach before opening any slides, never in travel mode. All chassis twist on most surfaces putting everything out of alignment, even if you think it’s level. Level first. Hope this helps. 🏁🇺🇸

Good idea, thanks!
