Just to reinforce. I have run my M715 on 12 volts for almost 25 years now using the 3 lever light switch. Just make sure you have 12 volt bulbs in all locations.

Yes, the oil light should come on with the key and stay on until oil pressure is achieved. The test for it is to ground the lead to the sensor with the key on and the light should come on. I don’t remember and didn’t look it up, but I think the 4x4 light also glows when its leads are...

The voltage drop at the engine wiring harness block to me seems very odd. Does it go back up when the key is off?

My personal opinion is that the military never intended them to be towbar towed more than a few miles. At least that is how the tow bar TM reads. Anything long distance would be covered by a wrecker picking up the front or a trailer it seems.

You could also get one of those RV vehicle towing brake acuator things that actually push the pedal. Then plumbing air into the rear vehicle air system would ensure good brakes with less pedal travel. I didn’t mention that or the airpack J pipe trick in my first reply. Because anything is...

No, the M35A2 doesn’t get to let the brakes be remotely activated. I have a pretty large number of miles over the years of M35 pulling M35 with the tow bar. Stock M35 brakes that are properly adjusted are very good brakes. I never really had any issues with stopping. Going faster than 30-40...

Several really hard crash stops from about 10 mph has worked for me. Even though nothing in any manual suggest doing that. I have been at the point you are now with nothing left to try or lose and 3-5 good sustained stomping/skiddings has done the trick.

Looking in the TM9-2320-2890-34 section 2-35 it talks about your issues. Check and make sure the fluid is at the proper level is about every other line. Then it goes through the vacuum and governor issues for shifting trouble. I goes into replacing the main pump once you get to not moving...

I have used Chevy V8 distributor gaskets on mine as well.

I think the what are you working on question was referring to the CUCV model. They all had the same set of gears inside the tail shaft. But, the M1009 trucks got a fancy little reduction box to go between the tail shaft and the speedometer cable because of the different axle ratio they have. You...

I was thinking 12si when I wrote that the CS130 and it were the same mount. Sorry. I also miss named the AD244. I have no clue what a DS244 is or why I wrote that. Here is a video comparing different GM alternators over the decades, their mounts and plugs:

I don’t have an exact answer for you. The 6.5 serpentine belt set up had an early set up with the alternator on the driver side and a later set up with the alternator on the passenger side of a single alternator system. The early set up was made for the CS130. Actually, with a pulley swap a...

I hadn’t thought of that. Good idea. The shifting at redline thing is what I was suggesting by going through the gears in low range. I just didn’t write it correctly. If it shifts by a mechanical method only and stays in gear then. That means you are back to the vacuum parts or maybe the...

Does it stay in 3rd if you shift manually?
