No, IMHO you have proven that TCM is bad That makes the third one in a row that turned out to have had a bad I/O port on the TCM ronbo-3 steelsoldiers and now you. I would have thought the PCS would be a robust and reliable unit but that does not seem to be so.

They don't have to blow up to fail but they usually do.

Makes sense to me, I will bet if you pull the cover off of the PCB you will find some fried components on the circuit board. You are saying the volt meter does not show the usual drop in voltage as the glow plugs draw current from the batteries yes?

Funny they still post this right below the statement they are no longer taking orders. " Today, these same Humvee repair parts are available to you. By purchasing directly from AM General, you will receive the same high-quality, original equipment parts that our U.S. Armed Forces and allies...

WTH??

You have at least the about 1/3 of the mounting hardware, the missing pieces are the truck sides of the mounts and the rubber isolators/special washers

Here was a quick search of a few sold shelters, the first two are NOS, the bracket is likely OEM as the A/C units were stupid heavy. https://www.govplanet.com/jsp/s/search.ips?k=S-788&sm=1&mf=1 And another NOS...

Pictures would help, I see them going from $600 or so on up, I bought a real nice one that was delivered all the way from Houston for $1000 and a NOS one for around $1750. I did watch one in disbelief go for over 5K, there was nothing special about it, only that least two folks wanted it...

The first thing you need to do is pull the TCM box and open it up, water intrusion is very common, sometimes you can dry them out, sometimes it is too late. Yes there are a couple different styles of TCM boxes and TCMs themselves, all TCMs will interchange, some have different shift points...

Yes, that is C and D on the transmission connector not the J1 TCM, you would need a special cable (as it states) because it is very difficult to access the transmission connector to measure it with meter leads. Notice it does not reference J1 in the procedure, only the special test cable, that...

Great Tip!! The first thing I do when doing any serious work on any HMMWV is to pull the tires, makes everything easier, a real plus is to have it on a lift at the same time. I drop a couple 4x4 blocks at the base of the lift towers and when the lift is put all the way down the geared hubs just...

You may want to think of fabricating these in bulk, there are allot of ambulances out there with no steps, seems the doors are not too difficult but the steps are.

I will again try to explain, thes pictures in your post are of the J1 connector at the TCM, the C and D pins on this connector have nothing to do with the PCS circuit, however the lower case k and g are part of the PCS circuit, you reported seeing 4.8 ohms there which would be in line with a...

Again the C and D pins associated with the PCS circuit are at the transmission connector not the J1 TCM connector You are looking at the wrong connector for the C and D pins, look at the schematic I posted above and it is simple to see. You will not get continuity at the C and D pins at the...

The cam is driven by a chain off of the crank, the IP is gear driven off of the cam. So standing in front of the engine the crank and cam turn clockwise and the IP turns counter clockwise.

Welcome to the SS forums!!

If as you stated earlier you are seeing 4.8 ohms at the J1 TCM connector lower case k and g then the PCS coil is probably OK. If you do see 4.8 ohms at k and g then it is time to pull the TCM, box and all and put it on the bench and open it up and check for moisture. If everything is dry then...

The C and D you see on the schematic is for the connector at the trans not at the TCM, the ones you want to look at at the cannon plug (J1) for the TCM is lower case k and g D and C on that connector is used for something else.

It sounds like you have a non functional TSU or a mismatched TSU Here is the link to the sticky where you can see what TSU you need for your PCB https://www.steelsoldiers.com/threads/pcb-eess-smartstart-s3-i-pics-info.164930/ I have never seen a wait light when fully warmed up (other than a...

You said you had 4.8 ohms from k and g was that with the cannon plug removed from the TCM box? If so you likely have the same thing at C and D, Swapping is simple just unbolt the TCM case (4 1/4" nuts) from underneath the body and pull the box.
