I need to repaint the crosses on my M996A1 and can't find flat red paint anywhere. Does anyone on the forum know who sells it? I know this sounds pretty simple but the only flat red I've found is more orange than red. TIA, Kurt

Switches generally aren't voltage dependent until you get into high voltage or high current applications. The thing you have to consider with a battery disconnect switch is that it has to be capable of handling the extremely high currents that starter motors draw. This can be on the order of...

Check the metal tags on your headlight wiring and see if you haven't got a 91 wire cross-connected to a 17 or 18 on the headlights. 91 is a ground in the harness and if you feed power to it thru the high or low feed it will trip the breaker and give you darkness (originally pioneered by George...

They're called "captive screws" and you can find them here: http://military-fasteners.elitefastenersinc.com/item/nas-fasteners/nas-military-fasteners-hardware-components/nas12

I will admit that the Stewart Warner gauges are the best of the bunch and the Dixon gauges aren't bad but the Faria stuff is junk. They would fail all the time in the 151's and I've replaced all but 1 in my HMMWV.

The time delay relay is a problematic item and one you should carry as a spare. Luckily, the failure mode is the fan running continuously which is noisy but won't hurt anything other than wasting power. With the engine running you should be able to unplug either of the connectors and watch the...

The repair entails removing the half-shaft and replacing the seal. It's not too difficult a job for an afternoon. Kurt

Years ago I bought a couple of M37s out of Tooele Army Depot and found 2 fully loaded 5.56 mags under the drivers seat!

With the exception of the fuel level gauge and voltmeter, The gauges in M series trucks are really just current meters and the sending units are just variable resistors controlling the flow of current through the gauge. It does make troubleshooting a bit easier though. An open connection reads...

Bite the bullet and pull your fan clutch off and replace the O rings in it. The trucks that have been sitting for long periods can trash the O rings and spring leaks when they try to start recycling again. Wear gloves and keep bandaids handy, you'll need them. This isn't a difficult job but...

Using the correct glow plugs is critical for good starting in the HMMWV. There are several options for glow plugs but the real difference is are they the older type that would swell up and cause removal problems or the more expensive non-swelling plugs that some dealers have over priced. The...

This is a topic that has several answers because the WAIT light behaves differently depending on which Protective Control Box is installed in your truck. The original Prestolite boxes turned the glow plugs on for about 11 seconds and would cycle them until the engine started. You could observe...

I'm going to assume your going to talk to other military radios from your HMMWV in which case the squelch tones and 50 Khz channel spacing don't make much difference since the other radios are doing the same thing. Now if you plan on talking to your buddies Icom or Yaesu your going to have...

First thing is to get a wattmeter and see if the radio is outputting any power. A simple CB wattmeter will work here since your not making qualitative measurements. If the radio is outputting then you need to figure out if it's on frequency and is the handset functional? Swap the handsets and...

There are a couple of ways to make 60 cycle power from 400 cycle sources but they're expensive and not very practical. Early methods were with "rotary converters" which are all that dynamotors really are. The electronic converters come in 2 flavors, modified sine wave and pure sine wave...

Another antenna that is usable for UHF radios is the AS()GRC-206 antenna. It's meant to be used with radios like the PRC-113 and operates in both the VHF and UHF aircraft bands. They might be a bit more available than the Harris antennas. The antenna mounts in the same footprint as the 3900...

To answer your question, no, the AS-3900 is a VHF antenna and it will not match up for use in the UHF frequencies. An ideal antenna would be the Harris RF-390AT that operates from 30-512 Mhz. They're hard to find but very nice whip antennas. That's what I have mounted on my HMMWV. There are...

Steve is correct here, your steering system has air getting into it somewhere. Take a good look at all of your steering hoses and see if there's and wetness on them. The pump and steering box are Saginaw units and aren't specific to the HMMWV. You can pick them up at any parts store or...

Could someone with the authority to do so please lengthen the inactivity timeout for the forums? Quite often if I'm trying to answer a technical question the session times out before I get through typing a reply and it requires me to sign in again to make the post. This requires that I do a...
