that noise is the acc. relay.. it looks like a lawn tractor starter relay.. How about you stop spending money, (with respect) and just clean all the grounds, including the ground breaker on the firewall, there is a major ground on the block in front of the starter, and it also goes to the frame behind the left steer tire. there are also grounds behind the dash at the left corner and the right side by the fuse panel... clean all of these and the eyelets.. then retest.. are you having issues with turn signals not working right?

So, I have mixed opinions on ''Rat Rod's''.. As for me,, I love my truck but dont make enough money to buy much, so I collect parts, and I beleive GOD puts them there for me to find.. Take these little beautie's for example.. The Heat shields are NEW take offs, the owner wanted chrome, and said throw those P.O.S. shields in the trash!! OK!!... the wire in the cabinet is good wire that I pulled from high voltage control panels at my City Job, It will be my new wiring for the whole truck. The heavy wire was from 480 volt A/C,, the light wires are 10 and 12 gauge,, and the Kerker Exh. pipe is what was in our scrap dumpster today... It will be the stack for my KB-7.. I have been collecting parts for over a year.. I know that some folks wont agree with my method's. But my wallet sure does... I really need to get back on it, I have been fixing my everyday trucks lately.. jojo

ok, V-Mac II has a 5-7 second delay after turning the key off.. that is normal.. the black relay looking thing in the picture is a ground breaker, it looks rough. Clean the contacts. do the same for the red one next to it. also, it sounds almost like the ignition switch is bad. There is also an accessory relay below the ash tray, it can also cause these issues.. Jojo

That rubbed spot on the push rod tells me that the slack adjuster may be to short, or the chamber is not mounted in the correct holes for the slack adj. Length. When the brakes are released the clevis would have to be angled upward, therefore rubbing on the hole in the brake chamber. Paul, it does look like it is passed 90 degrees..

Thanks bud. I'm proud of it..

There is a tab for it.. I forget where, and I can't see it on my phone.. I think it's in a drop down menu on the home page

Mech.. the ASET- series uses a Mack branded engine brake called Power leash... There are 2 rings per celenoid. The bottom one will cause the engine brake to stay on at all times if it fails. Regardless of switch position. Good question about weak operation or no operation..

I had no luck clearing out pictures.. so after a while I just made a couple $25.00 donations, now I have a boatload of storage..

All of these points seem good to me.. I'm grabbing at straws.. I wonder if the front drive axle is not braking good enough, causing all the brake effort being sent to the rear axle.another question I have is,,,,. Do the brakes grab hard and fast with a slight push of the pedal? Which would indicate a bad treadle valve. I would also like to see pictures of the brake chambers mounting position, along with slack adjuster length.. I hate to question another mechanic that I don't know personally, but it seems odd that so many new parts have been installed and the problem still exists.

Yes to all that, and you can also jump power off the alternator to the pin sicking out of the valve cover and hear the celenoid click. Front I s low and both are high. Be careful pulling the valve cover, the celenoid wire is shet and doesn't allow you to lift the valve cover very high.. I assume AI engine and not an MP-7

Sir... we tried to keep you from spending a bunch of money on this.. I'm sorry.. a lot of this should have been diagnostics and tests.. do you know what type of valve is delivering the 'service air' to the brake chambers? all 4 brake chambers should be plumbed to the same valve through 2 ABS valves, one on each side, unless you have a butterfly valve set-up centrally located on a cross member.. can you post pics of the ABS valves? I'm trying, as-is others here to help you.. I sure hope whoever adjust's your brakes.... know's how...

I have been slow to respond on this one.. A while back, I saw some videos of a guy that will take a running truck ie: GMC with a 6V DD, and blow it up.. He was driving the truck in the video.. I was pissed, because the truck looked good and it sounded better.. For some reason it was funny to destroy it.. I saw a truck that could have been used as anything other than trash.. Like a camper puller.. OR part it out to guys like us that need the good parts.. Rat rods dont upset me too much, because there is some creativity and preservation. I have an OLD truck that I CAN NOT afford to build correctly, so I am just going to do as good a job as I can to make it road worthy.. it's 75 years old.. anyway, I guess it is their personal thing, that can make some of us cringe.. I'm sure my truck will make a true IH guy cringe... Jojo

any news on this??

Bingo!!! I love it..

Ohh.. the "Green New Deal" thingy.. I like clean air. Sure wish A.O.C. would keep her mouth shut, to help reduce methane emissions..

I was scratching my head when I read it.. maybe it's a typo or unfinished question.. I was always taught that the black smoke is wasted fuel and horsepower coming out of the pipe.. we'll see...

The sad part for me is that I cant even tell if they are REAL women.. I'm so afraid to look, just in the case they are MEN.. I hate this new kinda Gay.. at least the Old kinda Gay was easy to figure out.. I feel bad for guys who are trying to date someone, especially with the intentions of having a WIFE... Anyone remember WIVE's?? That's the 'Split tail' one of the pair.. Just say'n.... A very confused,, Jojo

Im watching CBS Nigthly News.. Its too bad Biden doesnt put the same effort to secure N.Y.C.,, into our southern border wall.. Oh well.. I expect a smooth day tomorrow, but the Lib News will find up to 5 Idiots that will do something dumb that fits their agenda..

Holy Crap... I had no idea... What a shame....

So what is that?? engine model? and what is the sensor lookin thing? What a friggin Mess...!!

Hell, try Gorilla tape, and let me know how it holds.. I havent used that product yet..

Looks like and E-6.. so you will need some SAE Super Glue, E-7's use metric Super Glue. 6 cans of brake clean, a new roll of Duct Tape, and a torch.. Good luck.. Jojo

Mech.. my old timer gave me the nickname 'Clevis' 20+ years ago.. I was chasing a front brake issue on a late 70's DM.. after an hour or so,. Well.. it was a rusted clevis pin.. Too funny, and true..

Is it me, or does the frame look twisted in the second picture? Maybe do like Mechohaulic said and swap the brakes and drums to see if the issue follows .. this test is free. Buying brakes and drums gets expensive quick.

I would like to be there also . I think I would jack the drives up and try adjusting the brakes till they just barely scrub, kinda like drums brakes on a pick up truck. Then test drive it.. it is tough when you are not there to see the issue.. jojo
