Take the tank out of the vehicle and give it a thorough cleaning on the bench then hit the pump with 24 volts and see what it does. You might want to let it soak with some white vinegar in it to dissolve any gunk that's built up in it over the years. These things hardly ever get used and...

There is a series of manuals that are primarily for the VRC-12 family of radios but part of the manuals discuss installation of the VIC-1s in various vehicles. That series of manuals is the TM 11 5820-401-20 series. If you search around online they are all available through places like...

There's a good chance that that 3 mA is current through the alternator. At that level it's negligible.

BigNutz, Welcome to Steel Soldiers! One of the first things to learn is that the advanced search block in the upper right corner of the page is your friend and it'll take you wherever you want to go. Most of what your going to run into (figuratively, not literally) has already been asked and...

OK gentlemen, 1) I live here in California, 2) Over the past 35 years I have driven my M37, M151, M980, and M997 thousands of miles throughout the state. 3) I care about the DMV regulations affecting us as much as anyone else and as past MVCC President I cared then too but the MVCC is the local...

When these radios were first produced in the '60s they were "water resistant". That meant they could have been submerged in water for short periods without suffering any negative affects. 50 years later the cover O rings have all dried out and flattened and time has taken it's toll on them...

I like the idea of relocating the batteries the way you did but why didn't you place the negative lead frontmost and the positive lead rearmost with a short jumper between the batteries? That way none of the cables overlap each other. Did you build up the tray or was it something you found and...

Bulldogger, The HMMWVs only used alternators. All generating devices have brushes the difference is the brushes ride on slip rings that energize the field winding in an alternator and the brushes in a generator ride on the commutator that's the output . Your correct about cleaning out the...

Last go round with batteries I went with 24Fs from Costco figuring I could get them replaced almost anywhere if I had a problem with them. Make sure you get the ones with the flat covers and the stock hold down bracket will work fine and since they're the same length they fit in the battery...

Another indicator that the noise is coming from the alternator is the vibration of the cover over the electrical connectors. And Cam, Marraige Bootcamp is on tonight. Did you forget? LOL fat lady sings

Are we going to see this at Plymouth?

I've been running a pair of Hella H4's in my truck for 18 years now. Great lights, 24 volt, and DOT compliant.

Hi Ken, may I suggest that you use the search function in the upper right corner of this page and search for no start. There are literally dozens of postings on this subject that will give you all the answers you need and more. This is a very common topic on every HMMWV online forum. Retired...

That Gear Report is a great checklist for a prospective owner but something I've noticed missing from it is you want to get under the truck and rap on the frame with a hammer. It's made from pretty good steel and should "ring" when hit. If it gives you a dull thunk it means the frame is rusty...

My understanding is that GM (actually Detroit Diesel) made the 6.2L engines from 1982 until 1993 to put behind their trucks and AMG adapted it for use in the HMMWV. When they needed more power GM upped the displacement to 6.5L and built them for a much shorter period than the 6.2's. When they...

Probably as scarce a piece of sheet metal as your ever going to find. I just had one of my mounts CAD drawn and will be looking for a water jet cutter who could make up a half dozen of them for me. At that point I could either sell the flat blanks or find some sheet metal shop to bend them up...

Watch your voltmeter when the glow plugs are cycling and if you don't see the meter "dipping" as the plugs come on it's time to check them with a multimeter. They should read around 5 ohms and anything higher means they're on their way out and need to be changed. Remember to use some...

Something to be aware of when working with these mast sections is that they're made of copper plated steel and if left together untreated they will eventually rust "freeze" and at that point they're basically scrap tubing. When assembling your antenna always use some type of grease between the...

WireFox, the 117A-D series radios all have a single xx90 battery in the battery box unlike the later radios like the PRC-113, 117F, 138, and 150 that all use the dual width battery boxes. These older series radio battery boxes have become pretty hard to find. There are plenty of the plastic...
