I went out to the bus/car port and ran the OTR ac for 15 mins with my HF ac gauges and IR temp gun.
OAT was 90*f & high humidity. Inside bus temp was mid 80s.
Static system pressure was 100 psi. Refigerant Pressure Temperature Chart said it should be 104 psi. close enough
Started engine, set HI IDLE. 10 mins after turning on the OTR, both cabin and cockpit, low side was 30 psi and high side was 215 psi. 50*f air was blowing from all vent inside the bus.
Coldest part of the brass area of the low pressure service valve was 54*f. Hottest part of the brass area of the high pressure service valve area was 160*f.
Opened the condenser door several times and all times the ball in the lower sight glass was at the top, and the upper ball was on the bottom. Filter felt equally warm to the touch at both ends.
Both heads with unloader valves were hot to the touch on top, and not so hot to the touch on the bottom.
After 15 min gauge pressure were 28/210.
I hope this helps?

Ceramic roller on the rocker arm broke. I’m running but it dinged up the camshaft. We did a minor cam grind…I’m told camshafts are on national backorder.
I think the ceramic roller is a BS design. Anyone know if there’s an aftermarket steel roller rocker?
Only about 8000 miles to go if she holds!

Before spending money find out why the voltage is varying. The alternator output should be steady so start there to see if it is jumping around. Check cable connections, especially at the chassis ground.
All the equalizer does is distribute charging current so the alternator output (presumed 24V) is 1/2 of that value on the 12V side of the battery system.
The 13.65 value is 1/2 of the high 24V value so the equalizer is working as intended. My guess is it is a connection issue or the 50DN may be showing signs of an internal issue.

Dick, my AB system does not like cold temps, it will shut down below 32 degrees or so. The bay heater is a must during cold weather operation. Wondering, is yours sensitive to cold temps too?

Same with me Art, I like the standard fixtures also. Thanks for sharing the bulb info, I was also thinking about lining the inside of the bulb housings with that aluminum foil adhesive tape to get better reflection.

No adjustment on KGG-4232-24vdc Versa valve.
Sorry for the late response, getting the coach ready for a run to Fountain Lake.

The tensioner can be adjusted with a single adjustable wrench, or both 1/2″ and 3/4″ open ended wrenches. As long as the rest of the nuts are pretty snug, you can break the LH and RH jam nuts at each end of the turnbuckle with just the 3/4″ wrench. You then adjust the turnbuckle with the 1/2″ wrench. Again, just a single 3/4″ wrench is needed to tighten the jam nuts when you’re finished.

I found that a big pipe wrench works well to pivot the fan assembly up to apply tension to the belts in order to measure the overall distance needed for the tensioner. I took this picture just as a reference after the job was complete. The tensioner obviously wasn’t there yet when I took the measurement. The pipe wrench method is an easy two-person job, and a very awkward solo job. I found it simpler to use a ratchet strap between a bracket on the bus frame above the left rear engine door hinges and the swing arm assembly. That might not be practical for most, but I have my coolant surge tank removed at the moment. Lots of room for me. I didn’t get a picture using the strap.

I ordered everything from McMaster-Carr. The turnbuckle connecting rod was pretty hard to find, and I eventually had to change from zinc-plated steel to stainless steel due to a back order. That added about $50 to the cost. The total of around $200 was more than I expected, but still worth it. I also ordered some greater quantities of nuts and washers to reduce the per-unit cost, which bumped the total up a bit. This image is just a sample order I created for this post.

Here’s what I came up with. It has plenty of range to give both good belt tension and ample slack for changing belts. I batted around a few ideas to achieve the proper length while retaining maximum adjustment range, and the 6″ turnbuckle rod with 2″ male threads at each end ended up being the key. The female turnbuckle rods weren’t threaded deep enough to suit me.
