Well it happened and I need to understand how. I did the DHM over ten years ago and never had a problem. Fortunately, I was able to disconnect the front negative cable in under 30 seconds. It was a cold start and nothing heated up, smoked, or melted down. Truck was bought from the military...

Really need some help. I've replaced the PS pump and the hydroboost unit. Still nothing. No leaks or blockages that I can detect. Jacked up front end and got the air out of the system while pumping the brakes and turning lock to lock per the TM.

While my son was backing a trailer, the PS went out. Expected to see a leaking hose but all hoses and belts under hood looked fine. Some PS fluid was dripping from the bottom of the reservoir but that was due to foaming and it was coming out the top. Fluid level was good. Brake system was...

Just found the root cause of my M1009 vibration; PS bracket was broken in two places. Can this be welded together and be functional or should I start looking for a new one? Anyone with a part number for this?

I have two M1009s; on one, the factory voltmeter appears to always read battery voltage, even when the truck is off. It is in the yellow zone when off. On the other, when I turn the ignition off, the voltage drops to the far left (red zone), like it is not reading any voltage. Both trucks are...

Can someone help me troubleshoot this? Stock M1009, 24 VDC setup, going through resistor bank. Multimeter ground to rear of driver side alternator, positive to top of glow plug relay - reading 24.5 VDC, everything off. Upon startup, engine cold, I read 7.5 VDC at this point while the glow...

Is there a trick to putting the top of the IP (the part with the electrical connections and houses the fuel shut-off solenoid) on correctly? The solenoid works fine off and the bowl is full of fuel. New stock filter and new lift pump. Showing 8 to 10 psi to the IP but no smoke and no start...

Can you believe it? Someone unbolted the conical assembly at the transfer case and stole it along with the rear drive shaft in my M1009. I hate a thief! I had to replace a starter and noticed it while I was under there. Now I need another one. How much will this set me back? Anyone have...

I have an M1009 that I want to get running but it does not have any batteries in it. Can I take another M1009 and connect the NATO slave cable and get it to start? I don't want to invest in batteries if it want start and I was trying not to have to take my batteries out of the running CUCV...

Why does my M1009 master cylinder almost always have a small drop of brake fluid on the outside bottom? I had this issue with the old one and replaced it and still have the problem. Nothing seems to be coming from the rear where it bolts up; besides, if it did, it would have to run uphill due...

I just bought a low-profile LED third brake light and want to mount it on top of my M1009. It has two wires: black and yellow. How do I connect this to my truck? I already have a 4-pin trailer towing cable hooked in and thought it may be easier to just connect to that. I thought it would be...

What are the recommendations on adding a analog temperature gauge to the dash next to the voltmeter? Specifically, which one and how does it need to hook up to the engine?

My friend has a M1031 that has the problem of draining it's batteries after only a few days. He recently noticed (after dark) that with the key out, both GEN 1 and GEN 2 lights were glowing dimly. What wiring gremlin would cause this issue? The truck is in military stock configuration and...

I recently saw in a civi K-5 the hand straps mounted in the corners of the top for the rear seat passengers. I have a set that I want to mount in my M1009. My question is, what type of screws should I use in the fiberglass?

My CUCV has started the dreaded warm start problem. Starts fine when cold (winter) or just after sitting overnight in summer or after 6 or so hours after being driven. Other than a manual glow plug button, all electronics are stock. Starts up fine within a few minutes of shutting down but not...

For years, my 1984 M1009 has not missed a beat starting. Whether it was 20°F or 110°F, it fired right up. Lately, after sitting around an hour or two after fully warming up, it takes several tries to get it to start. Cold start is no issue; only warm after sitting. I have replaced the...

I saw a video of a M1009 in Europe with the amber side mounted turn signals. Looked very cool, and dare I say, even stock. What would it take to pull this off? I need the electrical wizards to show me what to tap into (Doghead??). Also, should they stay lit or only flash?

After fueling up at Sam's Club a few nights ago, the WIF light comes on and stays on occasionally. I can tell no difference in performance. As per the instructions, I stop and drain out the filter and the light stays off for a while. My question is: how much water does it take to trip the...

After much work, I have my dash indicators working properly. This is a video of a cold start of a 1984 M1009 at 50F this morning. Note the GEN 2 light stays on until the RPMs are high enough to activate the exciter (tap the accelerator); then the voltmeter gage goes from high yellow to green...

Need some direction on solving this problem. Stock 1984 M1009 from GL. Runs great except for the shake/shimmy at low idle. Not too noticeable at cold start-up fast idle. When it switches to low idle the motor shakes the front end and sounds like it is skipping. Lots of smoke. Motor mounts...
