I love when they say "recent" as in 8 months ago :eek: "The Title certificate for your recently purchased 1994 AM General M1097A1 HMMWV 2 Door Hard Top w/Helmet Top has been sent out by Fed-Ex Ground".

Assuming that truck has a 400A alt the engine is idling too slow, (in that case the tach should read around 850 RPM) and holding the steering against the locks or pressing real hard on the brake pedal is a good way to blow seals

If you are shifting the TC properly, with the engine off and the trans. in neutral then at times the shifting dogs do not line up making it difficult to get it into the range you want.

If you are talking about the way the TC shifts that is normal. Please close the door, 28 tonight geez......

Including the numbers on your alt. will help.

It actually can cause ground loops that can have unintended consequences, every device on a HMMWV has a specific ground return path. IMHO the only reason this ever got off the ground was because to install it you must "disturb" many of the original ground points and some found it "helped" when...

You mean something like this? I don't see it listed separately, best to put a want in the classifieds.

The TCM uses the crank sensor for engine rpm, nice sign wave, 4X the crank speed on the 6.5L.

Resistance when not running, all transmission speed sensors put out AC when in operation. The exception to this is the RPM sensor on the back of the early engines for daig use, they are simply a reed switch, open or closed

Fix the factory grounds and you will be fine, adding more grounds creates ground loops and more "weak" links IMHO

You probably have a bad ground to that light, when you check it with the lights off you are likely seeing continuity through the light filaments, that is why it goes away with the lights on. But to answer your question, no a dimmer switch cannot affect the ground.

I think they look better that way on any installation.

I am curious what you drive in the civy world? Almost every vehicle has lower oil pressure when at idle, especially when warm, only Fords have the same indicated pressure all the time and that is because what looks like a gauge is actually a mechanical idiot light, the Ford engine has a simple...

Since you removed the fuel cap and it made no difference it is not a vent issue, I would start looking at the return system any restriction there will cause a loss in power, you might want to remove the check valve in the top of the IP (the return line fitting) and inspect it, (careful not to...

What the OP needs is some documentation he can show the authorities that his HMMWV was produced without a turbo, I have no idea where to get it but someone probably does..

The REV trucks are nice but have many expensive and hard to find components.

I have done that, did not make any difference on my engine.

Most R1s are three speed trucks, there are some exceptions. DRMO stands for Defense Reutilization Marketing Office, that is where us old timers used to buy gov. surplus, the sales were handled by private contractors on gov. posts, now handled by by GP mostly off post

In fact the NSN number 2320-01-107-7155 is for a M998 BASIC truck which would not likely have the cast mount and variable rate spring. Yours is obviously a variable rate spring by the fact that the diameter of the coil tapers.

It does look like your truck is actually an R1, I have no idea why the data plate they used did not reflect that, actually the data plate does not state any model and the weight rating of a basic M998, they obviously just got lazy and used what ever they had, the plate on the passenger side was...
