If you take a picture of the manual button hooked up to the solenoid and post it, I should be able to tell.

Isn’t that evidence, in and of itself, that the solenoid is working? Or does yours actually bypass the solenoid?

If they win and don’t pay, doesn’t that get them banned from GP? How do they know who else is bidding to give them a call?

Yeah I worried about that myself, but I think it would be light if it happens at all. Not sure how much the winch was used by the soldiers but the cylinder has only the lightest of scuffing as you can see on this pic. You have to zoom in to see it there on the inboard side of the cylinder.

On my factory winch truck, I noticed that the cable path is really close to the lift cylinder, I think they are depending on the cable routing roller on the frame to keep the cable from rubbing on the cylinder too much. You can see on the below pic how close the cable is to the hydraulic lift...

I am in for 2 full sets for my A1 thanks!!!

Just a follow-up on this, I tore the whole PCU apart and there was some crud in there. I cleaned everything as best as I could and re-assembled but I re-used all of the existing o-rings and seats. It made a dramatic improvement in the leak down that would occur during the “check and hold” test...

Oh! Is that at the Antique Powerland? That’s sounds awesome! Do you have any info on the club or have a contact you could forward? thanks!

Do you air down the tires on the M1082 for that or just the truck tires?

Flying the colors for Memorial Day weekend.

Interesting, well it is definitely venting during a check and hold, but not a hold only, so I will pursue this as the culprit for now. Thanks for the help, very much appreciated. Been spending hours on this problem and neither the Army TM nor the Dana manual pointed in this direction for the...

so I was thinking about what you said about the vent. My PCU vents to the cab, and as-such is hard to check for leaks. I tried the rubber glove trick over the vent cap just now, and after the check and hold test, there seemed to be air coming out of this vent. Not enough to make a sound you...

I have been chasing leaks for hours and used gallons of bubble mix LOL I absolutly cannot for the life of me find any leaks ANYWHERE but some leaks around the wheel valves. To me, they don't seem significant enough to produce the rapid drop off in pressure on the control side when the system...

So playing with this a bit more, mine behaves as you say. When I energise control but NOT supply, the control lines eventually get to a point where the pressure stabalizes, and the QRVs stop dumping. However, when I do a "Check and Hold" which sends pressure first and then holds control, the...

On your video, if you send the shot of air and then let go, you are able to observe your tire pressure and the pressure in the control lines stays stable. On my truck, the pressure in the control lines does not stay stable. It is always dropping. I do have some slight leaks around my wheel...

If you energize the control solenoid but DO NOT give it a shot of air, what is supposed to happen? On my truck, as soon as you energize the control solenoid, the pressure as reported by the PCU transducer slowly rises until the tires begin to deflate out the QRVs... Is that normal? I suspect it...

Agreed, on a working truck (mine) the ECU switch status always reflects the physical status of the switch no matter what operating mode. @ckouba In addition to what @Ronmar suggests above, From the Dana Manual troubleshooting a Pressure Sensor code 31 (which I know we didn't have but the...

Yes, switch being unplugged make no difference to the behavior. To clarify what I mentioned in my previous post, the Test Tool reports the switch as closed at any and all times the system is at rest, whether the switch is plugged in or not. The instant the system tries to operate in any...

The pressure switch on the wet tank. Even when unplugged, the ECU reported its status as closed. This is my thought as well. Any time the system was trying to inflate, the Pressure switch would suddenly report "OPEN" to the ECU and would remain that way till we canceled the test. So what it...
