Dad he was a Texan, and when necessary you can protect yourself and family. I’m not a gun person, Don’t like guns much but I do carry a 9mm in a lock box in the bus and only once I took it out just in case. In Lordsburg New Mexico
I bet a lot of Prevost owners carry some kind of Gun in their buses??

circuit breakers don’t last forever ?
Last summer the air conditioner cb failed at our sticks & bricks. Changed it and no problems since. -
Are you measuring the voltage at the Equalizer?
-
Read the charge voltage levels for your new batteries.
Read the information for Li batteries about current levels at 32 or below, or above 32.
The chart show may be applicable for lead acid or AGM batteries, but only the Li manufacturer’s charging specifications are valid for those new batteries.

The Prevost maintenance schedule calls for all grease fittings to get lubed every 6200 miles (about 100 KM)
Historically owners have opted to do their maintenance annually and that means if they average more than that number of miles per year the coach is not getting the needed maintenance.
If someone other than yourself is doing your maintenance you have every right to expect it to be done properly, regardless of if you watch them do it or not. If you question whether it was done, it is a legitimate question and if you get a poor reaction from the people doing the work, it is the wrong place to take your coach.
Just to use that grease fitting as an example, if it is not greased the arm holding the roller will be able to tip sideways. That pushes the belt sideways. The net result is the belt starts getting chewed up, and it can or will wrap around the gear box shaft, possibly damaging the seal, and once the belt has failed the coach will over heat.
So the cost of a shot of grease is the cost of repairing or replacing the arm or its bushings, repairing or replacing the gear box, replacing the fan belt, and if you have no spare getting towed.
That makes asking questions pretty important. It also make proper maintenance pretty important.

Do you have a scan gauge to monitor engine performance or only the analog gauges? What are the actual temperature comparisons before and after. How long and steep of a grade led it to over heat?

Those calipers are usually very reliable, but over greasing and a bad automatic slack adjuster will make you think the caliper is bad.
Over greasing creates a hydraulic lock that inhibits the caliper from releasing. Clean out the excess grease and that problem is solved. You can evaluate the automatic adjuster by backing it off and then applying and releasing air to the brake chamber. I do it with shop air, but you can do it with the bus air system. You can see the slack adjuster being tightened, and you just want to make sure it does not overtighten.
If the slack adjuster bolt was not tight when you loosened it, the problem is likely not that. A hydraulic lock eventually will release it self over time usually.

Tom, as we discussed at the time, you were close but I was able to do a bit better particularly as regarded shipping from a local distributor at my shop rate. Thanks.

Great link! Certainly the best of the best if your fridge is laid out that way.

Jon, the secondary alternator is the one I assume charges the engine batteries. The big 50 DN is the 12 volt system. The alternator I replaced was a 24 volt unit.
I couldn’t get a read on voltage off the old unit so i replaced it with a new one.
New one does not read any voltage either when the engine is running. I must not be doing something right when taking the reading.
This is a 2001 Marathon unit. Detroit 60.
The indicator light is a solid red with no voltage reading. Marathon has it in their dash light section of the handbook as a secondary charge system indicator.

3 new Lifeline AGMs, 2 original Heart inverter/chargers, 1 possibly silly question:
When on genset or shore power after being on the road with minimal AC load, the chargers spend a lot of time at high amperage (90-110) recharging the batteries which ought to be pretty well charged by the engine 12V alternator.
Do the Hearts just want more charge than the Leece Neville? Anyone else find this to be the case?

either he knows how to work on R22 units, or he doesnt. . if he is knowledgeable about R22 units – then he’ll be able to do it. If he is a hack – then good luck. It isnt as easy as giving target pressures. there is ambient air temperature, inside termperature, etc . . . but you should try and get a 14-18 degree drop in air temperature.

Thanks for your acknowledgment, Jimmy.

Problem with me is, I like them all.
I really like that Bronco!
What kind of airplane? I like the old ones too.
