Few months ago I started having problems shutting down my HMMWV. I'd kill the switch and count to 5 before it would die. Pulled IP fuel cutoff plunger, totally clean and smooth. Checked the wires, they work fine. It was acting like the power was slowing dissipating away hence having to count to...

I'm switching out my 200amp alt to a 400amp alt. Anyone know if you "have to" run a second set of positive and negative battery cables to the 400 amp alternator? The 400 amp alt has two pos and two neg posts on it. I know you have to connect a jumper cable from the rear posts to the front posts...

I had all the pictures from this summer when I did a custom install of a Red Doc A/C Unit on my M998. Here's a link to my blog with the install article. If you like the WAGNUM: WAR WAGUNS blog there will be more good stuff to come. Stay tuned. Thanks Guys

FYI, I'm starting a HMMWV blog on DriveTribe.com "WAGNUM WAR WAGONS" Kind of a cool blog page started by the boys formerly of Top Gear. A conglomeration of anything to do with driving. If I can get 8 members to join then the blog page will go live. Any member of the blog page can post...

I'm looking to make my own airlift bumper. Does anyone have a drawing with dimensions of the bumper and brackets? Or, is there anyone in the Portland, Oregon Metro area that would let me come by and take some pics and measurements? Really appreciate the help. THX, Chris 503-730-5795

I can't seem to find a definitive answer on this. Some say 3500 rpm, others say 3600 rpm etc... I did the 4L80e 4 speed swap and I'm trying to set my shift points (Quick 4 TCM after market controller) so I'm maximizing what limited power I have. What is the redline difference between the 6.2 and...

Replaced my glow plugs today. 4 were swollen, managed to get them out with vice grips and a flat head. I don't know how old these glow plugs were but I was getting long cold starts with a lot of white smoke. Any thoughts / comments on how these look? Do these reveal any issues with my 6.5 n/a...

Been working on my Red Doc A/C install for a few weeks, thought I'd share what I did and why. Box came sealed up NOS manufactured in 2006, appeared unopened Heard a rumor that some kits don't come with the 5 groove pulley but mine did The card board on the back of the condenser kept...

Here are scanned copies of the full install instructions, packing slips, and templates for the HMMWV Red Dot A/C Kits. Everything that came with my NOS unopened kit. Might make a good sticky... -WAGS

Thought you guys might know the answer. A month ago I finished my 4L80e swap and used an aftermarket US Shift Quick 4 TCM controller. The only piece of the puzzle I have left is getting a tach signal to the TCM. I also just installed a NOS HMMWV tach and pulled signal for it from the two wires...

Got my 4L80e swap done! Drove the truck yesterday, ran great. Today I went to drive it and the TCM (Quick 4 aftermarket) wouldn't turn on. Turns out my 24v 30amp relay isn't working. My only guess is that 30amps must not have been enough? Does anyone know what amperage is correct for the relay...

Spoke to Niehoff tech today, not much help. I have a 6.5 with the Niehoff 200 amp dual 14/28 v alternator on my M998. I've decided to do the 4L80e upgrade and want to use the 14v side of my alt to charge my rear battery so I don't over draw from it. Problem: I followed Augi's write up on how...

My fan sometimes randomly cycles on and off before the engine reaches full temp (mine is 220 deg dead nuts). It has done this it at 120 deg, 160 deg, etc... It always works like it should when it hits 220 deg. Runs until it cools down, then shuts off. I've ordered a new temp sensor that goes...

I purchased a front winch bumper like the one in the pic below. Pic #1 Problem, I didn't realize that apparently I need 4 other related brackets (that aren't cheap) to mount it correctly. Also, the fairlead slot seems narrow (maybe Warn had a narrow drum and the capacity sucked?) So now I'm...

I've found a lot of good advice on what brand of battery cutoff switch (I bought a Pollak) to use, but I can't find any examples or photos of how / where guys actually installed the switch on HMMWV (not a 5-ton). Anyone out there have some pictures or advice of how they actually routed the wire...
