The non-hydraulic HMMWV winches have 2 high current cables running to them. Typically both cables run to the starter. Nothing relies on the frame as a return path for current. Because of the way the truck is constructed everything in the HMMWV either has a ground connection in the wiring harness...

After 3 of those useless switches I wired a normally closed switch in it's place and it turns on the brake lights as soon as the pedal leaves the stop. Part of the problem is there is no adjustment for free travel in the linkage and if you have properly functioning brakes they are stopping the...

There is no frame ground tie point in the supplemental harness but it wouldn't hurt to have one. Nothing else in the truck grounds to the frame.

If you use a piece of 1/2" pipe it will center everything nicely.

The best penetrating oil I've ever used is KROIL. A little hard to find but there's nothing better.

A simple trick to keep the shin in place while your doing your gym workout is to tie it to the starter with some plumber's teflon tape. That'll hold it on place and it'll squash out of the way when the bolts are tightened up.

Keep in mind that diesels like to run their own coolants. They're specifically formulated to prevent micro-bubbles that cause cylinder problems.

The sensor on the crossover pipe is the one that controls the fan, the one behind the alternator is the one that controls the gauge. There are plenty of reasons this may be happening. A bad time delay relay, a bad Cadillac valve, or a wire getting ready to fail. Take a look at the input...

Now all you need is an Iltis or Unimog to carry them around! That's how I got started into military vehicles. Then you end up with big green things in the driveway too!

I looked into buying them for people on the forums and they quoted me $.28 each. Minimum order was 5000 pieces so I passed on them. They're part number B-714 and are made by Caplugs. Unfortunately they're a unique size and searches of other manufacturers proven fruitless.

In a system with the 200A dual voltage alternator if you disconnect the ground leg (lead to the current shunt) the +24v side of the battery system will still be partially grounded thru the TCM so if you turned on anything that would normally be running on 24v it could still be seeing 12v. This...

Be careful if you have the 200 amp dual voltage alternator in your truck because a disconnect switch on the negative battery lead will still leave things grounded thru the mid battery connection. Remember that the TCM is powered thru that point and there is no shutoff for it. If your running...

The shunt is only used by the STE/ICE test set.

Here's a link to the Hummer Knowledge page that lists all the HMMWV filters: http://www.hummerknowledgebase.com/parts/list/005.html

I have a good friend with a helmet hardtop and we looked into doing this same thing but there are cutouts in the corners of the toolboxes. How did you get around them? Can you just flip the door and not the whole box?

The electrical system feeds 24v to the temp gauge and from there it goes directly to the sending unit and ground. The system is measuring the current flow thru the sensor as it's resistance changes with the temperature of the block. When the system has all good conductivity everything works...

It would be helpful to know what alternator/regulator you have in your truck. Troubleshooting is different for different models of A/Rs. Pictures would be even better! :tank: Warm weather tells the EESS box that glow plug activity isn't necessary. Something to be aware of because it's the...

That's an RT-524 or RT-246 not M-524/M-246. Both the 246 and 524 are 35 watt radios and generally aren't operated with an external amplifier. I have both available but shipping cross country for a 62 pound radio is expensive. The biggest problem with these radios isn't the equipment itself but...

Don't you just love bugging the Hams on 6 meters though with wideband FM?

I always thought that that was what this forum was???
