To check the glow plug relay attach one alligator clip with wire to the bottom post of the glow plug relay, it should have two orange wires on it. Attach the other end with clip to the probe on the test light, and the clip on the test light to ground, use the alternator bracket edge and scrape...

I just finished bypassing the Glow Plug card controller. Before doing this I checked every thing very carefully, so from reading the posts here and using a test light, long wires with alligator clips and a digital multi-meter I was able to check most of the functions of the system. Do you have...

Check out the batteries at your closest Caterpiilar dealer. I found that they have the best built batteries for holding up to vibration and the best warranty I could find.

I am not sure what the effect on the injectors are, but it sure does make the clicking sounds under the hood quieter. I think that may be the injector noise. Also, when I use the 2 cycle oil in the diesel, the slow drips from the injector pump stop.

Welcome to this site. Have you considered changing the oil? I use Mobil One Turbo Diesel 5w-40 it cranks really well in the cold. Of course, cold here is only mid to upper teens and that is becoming more rare.

Thanks for the information. Yes, please post photos, as this is on my to do list. I know I have at least one motor mount vibrating the entire vehicle.

My light was doing the same thing, i went into to dash and replaced the number one alt bulb, then the number two was out, along with some of the other dash bulbs. I replaced many of them, but found the problem with the number two alt. and some of the others is actually bad bulb sockets. I left...

First try tapping the voltmeter while the engine is running, i use the cap end of a small can of WD-40. Second check the # 12 fuse, it is a 10 amp one, this one goes to the voltmeter.

I have heard that this a problem on this vehicle, so when it was in the body shop I had them install the add-on frame supports before it could be a problem. It seems the designers made it a bit too weak in this spot for off road use. So I know it is a common problem and could put the steering...

I use 1/2 quart of 2 cycle oil with each half tank of fuel. I use this year round, but will add the Power Service Winterizer in the winter time. I can tell that the there is less noise under the hood.

Do you use a fuel additive in your CUCV, and if so: what product, how much, how often and what time of the year? Do you notice any results?

I use one quart of 2-cycle oil per tank in my M1009. Normally I never let it get below a half tank of fuel, so I add one pint of of 2-cycle at fill up. I have never noticed any smoke on idle or at highway speed. An additive lubricant is recommended due to the lubricity of the fuel being removed...

My original radiator starting leaking in the body shop just sitting there. I bought one that is exactly like OEM, but it was about $450.00. I got it from a local body shop supplier.

I think by the rattle that there is a pressure type valve in it. That would also explain the huge height of the thing- space for the valve. In any event my oil leaks stopped suddenly and completely when I got a tight seal on it.

Check your oil filler cap. It must be air tight. It works in conjunction with the CDR valve to keep a small amount of back pressure on the seals to keep them from leaking. There is a metal flange and rubber gasket beneath it. I took the handle part of a plastic grocery bag and wrapped it around...

I think the idea behind the moth balls may have been to deter mice. I am not sure that works, but seems like I have heard that before.

Isn't the oil pressure sending unit located directly above the oil filter on top of the engine block? Could that be the source of your oil leak?

I just replaced my burned out alternator #1 light bulb. It works now but now alternator # 2 does not. I think I arced the voltmeter while checking the lights. I replaced the blown fuse for the # 2 and checked all the other fuses, but still nothing.I used the good bulb from alternator # 1, so I...

Very nice.
