The cab and tire cylinders have safety check-valves built into them which will keep the load from falling if you should have a hose or fitting fail. There are restricted orifices in these circuits that keep the flow within the limits of the safety checks. The checks are basically a check ball...

Well y0u pass thur has to accomidate whatever the If I recall my measurements correctly, the shocks in the stock system only allow about 1.75” of total travel, and deflating only lowers about 1” from the set ride height... It isn’t much travel, and your pass-thru should be able to accommodate...

And a shock, yes you could as long as you can figure out the weight right and if the cab weight stays fairly constant. Not sure how shifting a 200# pax in and out of the center seat would effect it though...

Or figure out where the wire is chafing and shorting to ground to pull the extra current... If they have the right bulbs in them(i came up with 28 lights) they should total about 220W and pull around 16A at 13.8V... look for chafed wiring where it passes thru to the door, mine started popping...

If they are AGM batteries, you want to use AGM mode. AGM and plain lead acid batteries charge/absorb current at different rates for a given voltage. A smart charger uses the voltage vis current to determine the charge rate and state of charge and control things for best efficiency and best...

Have you driven one? That would probably be my first step if I was thinking about something like this... IMO, unless you are prepared to put an additional 4-5K into diffs and drivelines, you might be disappointed. Yes, the 4wd is nice off-road, and for it’s size it is a pretty maneuverable...

Yea, there are unicorns out there, you just have to keep looking:)

Looks like a score to me...

D1 is the memory location. 45-22 is the code (G solenoid circuit open). You can press the mode button to step thru the 5 memory locations(D1-D5). Write down any other faults in memory A mode on indicator light while a code is being displayed indicates a current fault, no mode indicator = a...

Yea, the batteries don’t care about the welding, in fact, a pair of batteries can weld just about anything on the truck for 30-45 minutes:) It is the weld current finding it’s way thru a ground loop and thru something more vital like engine and transmission ECU’s that can be an issue. So...

Before I pulled my instrunment shunt the other day, I connected a millivoltmeter to it, pressed the start inhibit and did a couple of longer crank cycles on it. It averaged around 15 MV while cranking but the meter did record a peak transient of 26MV. If the spec I found for the shunt is...

Considering the battery bank is grossly oversized for the engine/starter, no I would not find a good crank and start at 25% that surprising... Cat specs a pair of group 31’s in series(100AH) for their equipment that uses these engines. The 4 batt milspec bank is 240AH...

No, this is the same problem. Pin 30 on K11 gets power from CB77. When energized, K11 sends power to the start switches From it’s pin 87. When it de-energizes after engine start and reaching 15PSI of oil pressure, it sends that same CB77 power thru it’s de-energized contacts(pin 87A) to turn...

There is a A1 schematic up in the tech manual section near the manuals for the A0... This page shows the start control circuit...

Yea, they do it different on the A1. When you turn on the main switch do K11(alt excite) and K26(neutral start) energize? K11 gets it’s power from CB77 via the neutral start relay K26. K26 gets powered by the transmission controller and feeds K11 pin 86. The K11 coils path to ground is...

Well since you don’t have the truck...

What NDT said... Do you not have the fuse cover panel? There is a map inside it...

yea, that sounded like it was doing a pressure check(seals system, gives a shot of air to open wheel valves, reads pressure sensor, then vents system to close wheel valves) And it won’t do any of that till the pressure switch sees 117 on the wet tank. The system is twitchy on purpose so it will...

Sure it is the brakes and not the cab suspension? Does it behave differently with the cab air off?

Are y0u sure the wet tank pressure switch is reliably going over 117 PSI the switch closes at 117 and opens again at about 89 PSI to report tank/supply status to the controller. I don’t think it is going to respond until it sees that tank switch close...
