It's funny that the whole reason for the radio shelters is to block interference (spurious radio signals). This is now your problem. The design is that desired signals would be brought inside via an antenna cable. Maybe this can be done for a AM/FM broadcast radio? For cellular, there are...

I drove my M135 almost as a daily driver for many years and the transmission operated like any other, except for the violent 2-1 downshift. The 302 spent lots of time against the governor at 3400 RPMs.

Bring a gas can with an electric fuel pump and some 3/8 fuel hose. Disconnect the in-tank pump. And a couple of hot batteries. Check the points for corrosion, seems to happen when they sit. All three will most likely run, but I promise the brakes won't work.

My opinion is that a M135 as nice as appears in your picture is worth $6000. This is to a serious collector, not "craigslist".

What polarity box is on a 1995 truck?

Nope, you have the good old 302 gas engine. It wants gas. Numerous threads on this site about engine swaps. Nobody is really happy with what they did.

I have a hazy recollection of the GMCs being sold on GSA Auctions not many years ago. Those trucks always stick out in my mind because it amazes me that they served our government in various capacities for 60+ years. You can see they were used for brush trucks. In my opinion, they are worth...

Yes that is a big problem, I have the problem as well on a truck. I beat on the metal to break the rust, then vacuumed it out, then sandblasted down in the crevice as best as I could, then vacuumed again, then filled with cold galvanizing paint, then sealed the top with black silicone to keep...

Cool, so you have a 1971 AM General M35A2 without winch. Grab a new main data plate from one of the various vendors and stamp the frame number on it.

Welcome. Mainlander here up the road in League City. Holla if you need anything.

Fuel pressure, cranking amps, RPMs.

The registration number ending in 71 means it is a 1971 year model.

Well you learned something. Any time you are faced with a interconnected system and you don't know where the problem is, start diagnostics at one end and work forward.

"Still no fuel" where? Glow plug hole or filter?

Blue smoke means burning oil, start with the easy fixes, see if the turbocharger has oil seepage on either side. Take the truck on a hard run and see if it clears up after you check the turbocharger. Make sure you don't have oil dilution. On the Allison, check the modulator cable and the...

I would disconnect the fuel line between the filter and injection pump so you can see when and if fuel has made it that far.

Junk the entire dryer and replace, several how-to threads in FMTV forum.

Ouch. What happened is, when you disconnected the batteries with the switch, the alternator no longer had reference voltage and it ran away. Likely the protective control box has burned up components inside. There is a thread here about repairing it.

My 2 cents, if you are planning expeditions to the middle of nowhere, it's time you learned to DIY. Super easy to do, just need a Milwaukee Fuel impact or old school pneumatic and a tire hammer.

Use little pieces of the old seal to center the pane, and fill the rest of the void up with black silicone. Prevents the frame from rusting out.
