Just a small update... I've just been trying to drive the M1123 as much as possible. Rotated the tires, which I feel like I might try another wheel/tire combo in the future. In the last few days, I noticed coolant at the front of the truck. It looks like the radiator has started a small leak...

I can't possibly think of anything else, other than the TPS, or something in the injection pump that might have an effect while at a stoplight. The only other tiny wrinkle that I might notice is that the transmission on very rare occasion feels like it shifts at a higher rpm than most...

Just another quick update... The truck has crossed over the 45,000 mile mark and now has 1100 miles under my driving. The last days have been going over bolts and making sure things are still snug. The transmission feels like it is shifting pretty well, the engine has good oil pressure and the...

Small update... Although, my M1123 fuel system isn't perfect, I've started to think that my fueling problem comes from the dual lever brake switch in my truck. I actually tested my lights against a wall and figured out that my brake lights come on way too late. This is either from a contact...

Time for another update... A big thanks to Camo, for helping me with the AM General coolant surge tank. I was going to buy an aluminum tank and be done with it. But, the AM General surge tank allowed me to save a little money right now and it certainly helps. So, the truck is back on the road...

Yesterday was a little bit of a pain... With the combination of cutting windows and trimming them for fitting, I am also drilling a custom winch plate for my 20ft trailer. Having done a winch plate a few times, I swear this will be my last time, probably. Hand drilling all the holes and I've...

I will just find an aluminum one. Still can't believe the price on them though. I bought the cheapest one I could find, to keep costs down. An easy regret, after the fact. Live and learn. At least the leak is small and I can still run the truck for a short time period each day. The truck is...

Grrrr!!!! Just when I am working on one step forward.... Bam! Two steps back. Fortunately, for me. It looks to be something that emerged from a bad manufactured part. As I was driving to work today, I noticed the smell of coolant. I went over my hoses recently, so I was a tiny bit concerned...

The guy a bought it from was running a Ram 5500, using the 5th wheel kingpin, without the bed. All I did was adjust the height of the kingpin, to get it as level as I could. The semi truck has airbags and dump valves, so I wasn't too worried about being able to get under it. I just needed a...

Life is pretty funny sometimes... Path of least resistance kind of thing. Tomorrow, I will pull the instrument panel and inspection the firewall bolt. I remember building the instrument panel and don't remember any funny business behind there. But, it always pays to be thorough. Lastly, the...

Saw this thread, as I had just bought a 20ft trailer for moving some vehicles around. I've yet to actually tow the M1123 with it, just loaded it to see how things went. That being said, I've got a dually F-550, or my semi truck to actually pull my bigger loads. When I picked up the M1123, I...

I appreciate the replies. This is what I have done, to keep connections between certain components. The alternator in my diagram has a grounding strap that goes to the front of the engine and has no other grounds to the harness. That being said, I have made my own 6 gauge ground from the...

So, in going through the M1123 diagram.... Am I correct in seeing that the body lug behind the filter supplies ground to the engine harness and not the other way around? I was assuming the ground link was coming from the engine harness side, primarily from the PCB. However, it looks like the...

Okay... Mogman. You posted this picture a while back. It shows the ground wire from the alternator lug, and the various places it ties into the harness, plus the grounds it supplies to each component. Is it possible you have a greater expanded view of this diagram? It would very much help me...

This is one reason that I don't really like the grounding kits and prefer to now leave the system alone. Unless of course, something might need attention. I am using 6 gauge wiring and individual wiring straps for my ground connections. So far, I've just done the body ground behind the fuel...

It is from the harness that comes from the engine side and bolts to the body, just behind the fuel filter. I have already bypassed it then, by grounding the alternator ground lug to the rear of the engine block, then again, to the body ground lug behind the fuel filter. I haven't seen any other...

So, small update... I started working on grounds and discovered something. The body ground to the truck, from the harness was broken. So, I trimmed it back, to make a repair and it kept breaking back into the harness. Long story short, even after trimming the entire harness back, the entire...

Funny... I knew there might be a couple members that might take note. I've already taken the battery area into consideration. It definitely will spark if it touches the wall.... Ask me how I know. Even the rear battery negative is too close for comfort. I was thinking of lining the wall. But, I...

Smallish update... Brake line arrived and installed(it is such a tight fit in that area, it was nearly impossible without removing the brake caliper, but I finally got it, with plenty of negative words). Feels nice to continue testing again. First thing I decided to do, was pay attention to...

It has been a few days since I have updated the thread. In the last couple weeks, I've just been doing some light on road testing, working out the kinks. The truck seems to be running a little better every day and I have finally received all the new injectors. The other day, I took the truck...
