    Thanks to the pics from Dennis, I found my brake switches... see below.  However, it was my impression that one switch operated the brake lights and there other the cruise (I'm guessing the prints tell the story, so back to deciphering those, and looking for the infernal BRK SIG RLY.)

    My pressure switches are mounted on the brake tredel valve mounted on the wall in the front bay above the generator. If your brake lights are working, it’s something else, the same switch closure that operates the brake lights disengages the cruise.

     

    The switches are for the primary and secondary air systems (fwd & Aft), the switches are wired in parallel, either one will operate the lights or disengage the cruise. It’s kind of a pain to change them, you have to remove the valve from the firewall to do it. They are in there VERY tight. I ws able to do it without disconnecting any of the air lines.

  2. I’ve used these a lot, they are fine for low voltage in areas that do not get hot, they tend to go bad in high heat areas over time. They don’t contain enough flux in the solder to give real good flow, so I generally add a drop of rosin flux to the wires prior installation, the other comments about overlapping the wires or twisting them are both good practices, otherwise you are depending solely on the solder for the strength of the gap.

    BTW, these are not a new fad idea, I was using them in aircraft wiring 50+ years ago, although much more robust and higher quality items.

  3. If you do want to use a 1 piece solder sleeve, use one like these, I’ve used literally thousands of them in aircraft wiring, they are not cheap, and do require a high temp heat gun to shrink them, but these are very reliable mil-spec splices.  https://www.amazon.com/TE-CONNECTIVITY-RAYCHEM-D-110-35-TERMINAL/dp/B00LQP018E/ref=sr_1_4?crid=2WOCIZTXLDMD0&keywords=Raychem+solder+splices&qid=1691243191&sprefix=raychem+solder+splices%2Caps%2C102&sr=8-4

    All I CAN add or provide information on.....

    DO NOT USE A LOW TORQUE 3/8" RATCHET to tighten down the welded studs on the SS attaching hardware.  I snapped one off.  I then drilled a 1/4" hole and put in a SS hex bolt with Nylok nut on the rear.  NOW, Don't ask me WHY I had it apart or what the occasion was.  I can't recall nor can I even lie and make up a story.  It was off, as an assembly, so I could do some work or such.  Maybe I decided to replace the nuts with Nylok locking nuts to prevent vibration....???

    BUT, ONLY use a hand ratchet or wrench to remove or tighten the retaining nuts.  I would suggest that you use NEW (only NEW) Nyloks for the final assembly and then throw them away if you have to replace.  SS Nyloks are out there...as well as SS nuts which can be Double Nutted as well for security.

    NOW, I DO recommend that you look at the Clevis Hooks.  I replaced the Grade 2 Pins with Grade 5 (maybe Grade 8 bolts and Nylok nuts or double nutted them. Many folks over they years have reported pins breaking or see wear. Mine, after 5 years and some 35K miles were starting to show some wear....I DO remember laying on my back in Maine and putting in the new hardware with my grown son saying..."WHY are we doing this now?"  LOL

    My name plate was badly mangled from my incident, 2 of the studs were broken off. I got a couple of SS carriage bolts put in place of the, what a PITA drilling thru the old studs to get a pilot hole. All worked out, MUCH easier on the bench.

  5. I have a Voyager AOM-7694 monitor that has some dead lines on the monitor. I really don’t want to replace the monitor as none of the replacements support the tilt feature for the rear camera. I guess the real question is does anyone know of a repair facility that can put in a new display, I haven’t had any luck finding one.
