  1. Get a 12V sealed relay or similar: https://www.amazon.com/ONLINE-LED-STORE-Waterproof-Harness/dp/B01N66W2XF/ref=sr_1_5?keywords=12v+sealed+bosch+relay&qid=1558197179&s=gateway&sr=8-5 85: To Ground 86: To Generator IGN 87a: None 87: To ACR Isolation #1 30: To truck IGN If the generator has more on time than the truck then you'll want to swap 86 and 30. If you do that, however, you'll hear the relay click every time you key on the truck. That may get annoying after a couple years.
  2. I think the simplest way is to just manually turn your ACR rocker switch to off when running truck and generator at the same time. That'll uncombine the batteries and the truck charges/maintains its side and the house charges/maintains its side. But you can't forget. To do it automatically you'd need to make a relay setup that takes IGN from the truck, IGN from the generator, then when they both have 12V it sends that signal to the Isolation #1 input of the ACR so it uncombines the batteries when both of them are turned on. It'll have to be a relay system so it doesn't backfeed the two IGN circuits. How to wire that I'd have to think about it for a bit....

    First Build

    Took me some head scratching and I still had my fingers crossed behind my back on the PN for Glenn's ABS module. It was kind of a simple system though. The ACC/ACB/Fusion on this one is a whole different ball game. Take a truck that automatically safety brakes and then remove two brakes and 4000 lbs off of it, yea that's a bit of liability to guess on what will work. Needs track time.

    Jackalopee question

    Can you guys put a TrailCharger in your RV trailers? That is the unit they designed to charge trailer batteries off of the center pin ABS circuit after the trailer hotline got taken out.

    Jackalopee question

    The circuit is 40 or 50A Maxi fused. TMC standards require it to be 12.5V at 10A at the trailer end connection. A battery powered trailer hooked to the trailer ABS center pin will backfeed the IGN circuit and keeps the truck running. Prior to 98 the truck didn't care about backfeed and used the old 30A circuit breaker in the header. 98-01 you just needed to swap the ABS power and trailer hotline connectors that are side by side and interchangeable and you are set. 01+ with PLC the connectors had to be separated and truck had to come factory with ABS power but it could still be switchable to trailer hotline with a chop and a butt splice. Somewhere around 2013 or RSD brakes timeframe standards changed again and ABS power is the only thing that could be on the center pin and trailer hotline had to be removed. Trailer hotline has to be spec'd to be in the 2nd yellow 3731 connector. Long story short, I can't imagine a used truck not having a working trailer ABS center pin, so if you had to add a relay it may be powering trailer 'aux' or hotline? So it should work?
  7. Engine oil is legit for Sheppard gears. Dex II or III for TRW/Ross gears. Watch your max temps if using engine oil. Maybe put one of those sticky temp thermometers on the reservoir and check it out for awhile before swapping over. Don't dry steer it with 10-40 either, but a truck shouldn't be dry steered anyways.
  8. Can you post up a material list of wire size, length, and end fittings Glenn? I might be able to come up with a part # list of pre-made assemblies you can just buy.

    Truck battery charger

    Its fine on a Freightliner because they can handle it. Everything grounds to chassis then to battery so it'll find its way if it needs to. On those that ground via harnesses you gotta make sure your ground harness (the alt-cab-engine-starter-battery) is perfect and sized correctly if you switch the ground. Long ago I fried (like melted into a puddle of goo) both door modules, a sleeper clock, and an Autoshift beeper in one bad click. It sucked. A couple on the + side is safer for the others unless you really check it out. C-H disconnects are 175A or 300A, depending on which you buy. ECU's in a 06 will be fine being disconnected forever. Running a truck off a converter is the more risky part. Make sure it is good stable clean power, has a couple of batteries between truck draw and converter for 'filtering', and that the converter inserts into the correct ground loop (aka if converter charges to house batteries but plan to run the truck on its original charge/start then be sure to ground it right). Trucks are made to shut off an APU at key-on (TMC standard) and aren't really designed & tested to run off a external power so they might not even be right as OEM...
  10. 98-02. DS404's, 1710 drivelines, 7 series u-shift-it's, 15" cltches, EI front axles & kingpins, D-series 4S4M ABS, N14, no stability controls, no datalinks, no dash computers, no fairings, sheetmetal bumpers, steps, tanks. Every day old truck stuff. Feed it lower exhaust elbows, lower radiatior flanges, wheel seals, fix hood cracks and hope to not need injectors. Theres only a $15K budget......
  11. Top one is the pressure-check for your air dryer. It is going to drop F tank some pressure as it uses that and supply tank air to regen the dryer. But it shouldn't leak external though. https://www.anythingtruck.com/product/650-S4341003100.html Bottom one is pressure protection for an accessory. Can't see too well but kinda looks like it? Might need to chase its male threads as they die cast the threads as part of the valve, giving you a parting line down the middle of the threads that'll grow small bubbles. There are a million different versions of them so look for a 223-something stamped on it. That'll tell you what it is. 223-585-2 genuine (not a x-ref) at a KW dealer will be chased threads already w/ 1/4 NPT females both ends. At least it used to be...

  12. He's right about the cooler. The truck ones are stupid expensive. Its 120lbs of copper brass hanging under there, but required for a on-off fan. Even the bracket and skid plate that hangs it is crazy $. The water pipes are a low volume not cheap thing either. They are bent different and there are four of them now. I don't know how PB used to do it, but sometimes the radiator Xmember has to be changed out and sometimes you can just torch in the new hole. WTEC III has the trans ECU dry in the cab so there is like 50 wires that need to go through the firewall and like 50 more that have to come through the cab floor. There is the oil pressure sensor that needs to be added and I don't remember what speed sensor the old speedos used but it was only at Allison dealers and not truck dealers. Same for the rear yoke and new dipstick tube too, it is only at Allison. Drivelines have to have perfect angles (like 1.5deg tops) and you'll have to regear. The bus/RV backwards driven carrier won't be compatible so can't use that. Front engine mount will need to change so both of them will need to hang from the A-frame while that and the oil pan/pickup is getting transferred over. Most everything else is nuts and bolts, including CAT exhaust studs - everybody's favorite. Fun project but you were supposed to start this winter project in October! You are going to have truck and motorhome parts strung out for miles..... 😏 Might as well steal the RV's front air suspension too while the truck is all apart........................😊☺️

    Fuel spill insurance

    Had a few screwups around the country but its always been for work so never had to do the insurance part. So far has never crossed $10K in cleanup or involved the news either, knock on wood.... Be sure your tanks are low before shucking a driveline! Kinda sorta related, but third time you are caught forgetting to put a fuel cap back on you are fired actually. Work is pretty serious about fuel on the ground. We try to keep one of those New Pig Truck Bags in the trucks as much as practical to give us something to at least try to keep it contained. Don't plug the hole with every Calvin Klein you can find in the sleeper because the truckstop replacements suck!
  15. In 2002 the "mag switch" was usually a plastic bodied Cole Hersee, (now Littelfuse) switch. Gonna look like:
