"each gauge has a source signal from the component it’s reading. " The way the gauge "reads" the sensor is by displaying the amount of current flowing thru it. As the pressure or temperature changes the resistance of the sensor changes proportionally. This is accordance to Ohms Law or I =...

Theoretical Masterpiece

It's the drain for the fuel filter water seperator. With the engine running you momentarily crack it open to drain out any water that might has gotten into the fuel system. 99.999% of the time is stays shut. This stuff is all in the TM 9 2320-280-10 manual and something you should read cover...

The LS-671 speaker has a standard U-329 6-pin audio port on it that the headset can attach to. This is the regular speaker for the SINCGARS radios and with a little adaptation will work with other radios. My PRC-138 is wired through it's battery box to mount into one of the single SINCGARS...

Some of these gauges read current and not voltage so be careful.

You can do this by yourself if your meter leads are long enough to prop the meter up in the window so you can see it when your adjusting the potentiometer.

My personal favorites are the General Dynamics single earpiece models that have been sold onlins. They meet states requirement of not covering both ears , are comfortable to wear for long periods and are actually made by David Clark.

Yes, you always want to adjust the regulator after replacing it since theres no quaranty it was adjusted to match your alternator at the factory. It'll be in the ball park but needs to be tweaked into spec after installation.. Theoretically the short white line on the voltmeter is the 28 volt...

Your regulator is fried, either look online or go to the manufacturer, Southern Automotive. http://www.southernautomotive.com/catalog/product_info.php/products_id/101 PN : 2920-01-180-8666, Voltage Regulator Make sure this hasn't fried your batteries too and make sure to disconnect them...

These connectors are called Packard connectors and are commonly available on Ebay or from places like Erik's Supply. As Cam says, there is no #16. #17 is the high beam line, #18 is the low beam line and #91 is ground. The schematics for the trucks are located in the back of TM 9...

The typical failure with the 1025 alternator is the regulator. This is assuming it's the standard 60 amp alternator and hasn't been upgraded to the 100 or 200 amp alternator. They can be found on the auction site for between $60 and $100 or can be purchased from Southern Automotive so unless...

My white schedule 40 beadlocks are 17 7/16 outer diameter.

I sure hope you didn't pay top dollar for that Prestolite control box. They're the oldest of the control boxes and you'll need to make sure that the sensor in the water crossover tube is compatible with it. I'm not sure which box your replacing but the control boxes and the sensors need to be...

Trans cooler kits are available online. Why look for another solution when originals are available? There's no reason to make things more complicated.

With the engine running crack open the petcock and drain it into a glass jar so you can see when your getting clean fuel out. I ran a small hose down along the body panel so that the drain point is at the bottom of the footwell so I wouldn't run fuel down the panel and make a mess. The other...

There are dozens of antennas that are "right" for use on the HMMWV as has been stated here depending on the mission or the vintage of the truck your trying to configure. Here are just a few of them: Radio Antenna usage RT-246/524 AS-1729 "Old Family" Lo band VHF...

The easiest way to determine whether your engine is a 6.2 or a 6.5 is to remove the doghouse cover and look at the STE/ICE RPM sensor hold down bolt location. The 6.2 bolt is to the left of the sensor and the 6.5 bolt is to the right of the sensor.

Sounds like it shoulda been a schematic Cam! 🤪🤪

The way the HMMWV is wired the heavy gauge wire from the + battery terminal goes to the feedthru stud in the left front of the battery compartment in the battery compartment. Underneath the truck the cable attaches to the other side of the feedthru stud and goes directly to the starter motor...
