The truck has no clue what the voltage draw is. There is also no mechanism to increase voltage besides your right foot And the cold fast idle solenoid. The truck has 2 separate 12 volt systems. They join for starting, military radios, slave starting and the stock glow plug system. Otherwise...

Power goes from the headlight switch to the dimmer switch to the firewall plug and then to the headlights. If you aren’t getting the hi beam indicator then that means power isn’t getting to or through the switch at the base of the steering column. Check power there.

You can still run the engine without the intake manifold. The turbo can just spin by itself with no harm done.

Like anything mass produced. The 6.2 was made to work in all environments and a huge range of conditions. Also like all things mass produced there is a range of acceptable sizes and performance of many different components. As long as each part was within “tolerance”, it was ok to install it...

Thanks for watching. I used my iPhone 12 Pro Max to make the video.

Hold out for the fiberglass. The wood size for the stock seats is not a regular dimensional lumber size. Very time and equipment intensive work to make new boards. Unless you have access to a mill saw.

I think the deeper mark is the factory “Center” mark. Where you have it should be pretty close to max advance without some way of checking your actual timing. . However, just a tiny movement in either direction from where you are can have a huge seat of the pant feel difference.

Yes to total replacement over fixing a broken transmission. At this time complete transmissions are still cheaper than parts and time to fix a broken one. I have 2 or 3 broken ones stored away waiting for the day I find another broken one with different broken parts inside. All of our...

I bought a bag of 50 or 100 of those aluminum number tabs off ebay decades ago. Then I ruined a very high percentage of them trying to stamp numbers into the tags but not through the tags. Now I remove old ones off any wires getting thrown out and put them in a bag to search and search and...

It isn’t the horse power that kills the automatics. It is the relentless torque and compression stroke power surges. Even the NV4500 manual had to go through several upgrades to handle the 6BT over the years. It never did get “bullet proof.” I suggest that whatever transmission you end up going...

Gates belts that fit your truck correctly is what works for me. I even did a video about it:

Sorry. Yours is the last HMMWV I have seen with the hood open and that was a few years ago with the Duramax in there. I wasn’t going to open the gas/diesel/LS/Duramax can of worms. But since it came up. Torque is what to look for at as low an rpm as possible. The TPI 350 isn’t going to give...

Those TPI engines fit just fine in Chevy trucks that the 6.2 with a filter fit in. I actually seem to remember thinking the TPI intake looked short and small under the hood of a squarebody. I think it will fit. The best way to KNOW is to measure from the crank shaft to the top of the intake...

I swapped to Hagerty a year ago when USAA wouldn’t cover my pair of Dueces anymore. If you have another old non daily driver, swap it to Hagerty with your M35. It might make both vehicles cost about half what your single truck is running right now. At least that was my experience. Plus...

Do the axle shaft u-joints while you have it apart. They get stiff and can cause hard steering effort among other things.
