I have a 2002 M1078A1 (really an A0.5 since no batt disconnect and has the Polarity Protection Device vs the Load Balancing Battery Control Device). I have been investigating my PPD and battery cables due to age and an intermittent D1323 ( ECU INPUT VOLTAGE HIGH ) "CHECK TRANS" that will...

I have a 1995 M1079 that I’m looking to replace the batteries. I want to keep the 24v side AGM but go with lithium on the 12v side. The 12v system runs the stuff inside the camper and is hooked up to a solar array. I’d still like to charge the 12v with the alternator while driving too. Does...

Hi all, I have a new-to-me truck - and it's time to get it running, as it's been sitting for over a yeary now... After I took delivery with little info and dug in, I found out a few things: - 1997 truck - current wiring/boxes (dill boxes?) - no fuses (this was confusing until I got the cab...

I tried to download and save from this site however after the download I can only view page 1. When I select a different page it goes back to page one ?? Thanks for your help. Mike

Well I guess when you fix one the other one starts to go nuts.... My 1078A1 has been running fine. Today after sitting away I went out for a ride and it went into 5 and check trans came on. IT would reset when I stop and then as soon as I start driving go back to check trans an #5. Codes in...

Hey there, I'm working on an 1995 M1078 truck with an Allison MD3070 transmission and having some trouble. First off the LBCD (polarity distribution box) has a smallish wire with ring terminal im trying to figure out which polarity to connect it to. I didn't make a mark of whether it was from...

I hope this isn't a duplicate problem discussed on another thread. I've searched around and not found much on this particular problem. Anyway, cold weather starting has been a big problem on my A1. The engine block heater helps but still that air inlet heater pulls 70amps and seems to drag down...

Picked up a M1088A1 with a C7 motor and I’m having all kinds of electrical issues and missing parts one part I’m missing is a shunt that comes off the main harness from the cab going to the alternator, batteries etc and I believe it’s the source of my electrical issues anyone have any leads on...

Looking at the way we hope to use our M1078A1, an middle aged couple traveling with a dog or two in a land yacht, we hope to have a robust cab and chassis electrical and HVAC system separate from a habitat system. For many years we have camped and backpacked at more remote corners of the...

I have 3 trucks that all have the same problem going on with them. The mileage flashes, the no charge light comes on, the 24v gauge sits at 0 and the oil pressure gauge sits at 0. the 12v gauge also sits low but if I put the truck in gear it will jump up to 14v and the no charge light will go...

Well operation recover the inoperable M1083 went smoothly. Its now in a spot where it will sit for a month or two during the IL cold. I know most of the parts that are missing and can match them up to my 1078 but I have one part that was loose in the bed and a plug dangling by the battery box I...

Hello all and Happy 2024, I Just wanted to pick the brains of the sites seasoned owners, I'm working on a deal for a 1078, and when I went to look at it the alternator's 28V side wasn't pushing anything just the 14 Volts side. When starting the vehicle it goes to 28V for maybe a second then...

Hi all, I'm fairly new around here. I can't remember when I joined the forum, but have been reading heavily on the LMTV since early '23. I finally pulled the trigger on a Mar/2004 M1078A1 and learned quickly to enjoy chasing all of the gremlins and fixing them as best possible. My current focus...

I've seen a people do this a little but not too much quantitative info. Can the manual pump supply enough fluid with its tiny reservoir for both the cab raise and tire lower? Just from glancing at the volume, seems like it would run out of fluid with just one of these operations-if it could...

Did a search but didn't really find much. My truck is a 2008 M1078A1R with the factory winch. Truck is new to me and I am new to these trucks, so in the steep learning curve of a new S&S owner. The winch cable was loose on the drum and hanging down below the drum, so yesterday I thought I...

Hello I have a 2001 M1078A1 where the abs light stays on. Does anyone know how to troubleshoot the abs or read the abs codes ?

All right, I’m a bit stumped on some alternator and battery wiring on my truck that I just got. It’s an M1088A1 with the cat 3126. The previous owner has done some tinkering with it and I’m just trying to figure out a baseline before I do anything worse. The wiring on the alternator had the...

So, I have a DPST battery disconnect switch that disconnects the grounds from the 12v and 24v battery banks. The other day, I turned the disconnect switch, jumped in, turned the main power dash switch, dash lit up, hit the starter button…. Heard the starter lurch and all lights went off. Dead...
