Ok so today I finally started looking at the truck in more detail as I was realizing my employee just wasentngoing to figure it out and I found a broken negative cable from the battery to the starter/chassis ground. This totally explains my voltage issue and plan to have it repaired tomorrow...

Do you have the numbered wire info so I know what to test?

Thank you very much

Do you happen to have a wiring diagram from the starter to batteries? I just replaced starter by my employee did the work so I don’t know the wires original locations incase he swapped a wire.

Sure wish I had some pics but thanks for the info I will check that out tomorrow. I only know about ground strap from alternator to frame but figured there had to be another ground. I do have 4 batteries connected.

What is the power relay, The box under the spare tire? The batteries all have proper voltage and I have 12 v and 24 v in the proper locations of the battery disconnect solenoid and relay in the box next to the 4 batteries. What ground is on the battery bank, do you have a picture I can...

Hey everyone I am still trying to troubleshoot my issue with absolutely no luck. I have since rebuilt the starter and solenoid, replaced battery disconnect relays and replaced the battery voltage box under spare tire. I can’t for the life of me figure out what happened to my perfectly good truck...

Ahh yes i know those thanks. I have a charging system light in my dash and only power sometimes when ignition switch is on and truck won’t start or crank and i can’t figure it out.

Hi I have a 1078a1 with some electrical issues and wondering if you have a picture of the sticker that goes under the dash to tell the relay locations. I want to check the k11 and k26 but don’t know their location because my sticker is damaged and can’t find any info online. Thanks .

I’m having a similar issue as above. Would you mind posting a pic or link of what the PDP x1 and X1 connections look like and where they are located?

i sent you a conversation message and would like to connect I could use some help to get mine running again as i am stumped on my problem.

Hey There I know this is an old thread but I was wondering if you ever got your LMTV running? I also Have a 1078A1 in Puerto Rico that I got running perfectly and now im having inconsistent power to dash and no start after my employee left dash power switch on for 2 weeks and drained batteries...

Thanks for all the help, today I will be cleaning the terminals on the load box and on Friday ordered a new disconnect relay to update it because my truck had the old style with exposed wires. I will have an update by Wednesday hopefully, Im just waiting on the new relay from Midwest.

I did think of that but was worried about doing something incorrectly and damaging more electrical parts. Do you know where I can find more info on how someone did that successfully?

Thanks for the suggestion but all batteries were already charged over night with a large multi bank charger I bought from govplanet. volts are at 12.8 on each battery and volts are all over 12v and 24v on all post rely except the far left post as shown in my diagram.

I have checked voltage again and provided another diagram for reference. I also let check sit for about 1 1/2 hours with battery switch off then went to check voltage again and had 24v on the far left relay post. i then went into the cab and turned on green switch, heard relays click, had 12v...

Hey everyone, so my truck has been running perfect until today. I went to start and had no power at all in the cab except for a “Charging System” red light on the dash. My truck has battery disconnect near battery box and it’s always stored in off position. Today I turned the switch as usual and...

Hey Guys, I have an 803A 10kw and im without power in Puerto Rico and finally trying to get it set up with no luck. I have a 3 wire dryer 50 style plug wired to my breaker box. I have 1-white going to hot leg of breaker, 1-black going to other hot leg on breaker and Green going to sound. I have...

ok thanks for that info. i have that strap on the alt so I'm sure all is good. I'm going to check for shorts tomorrow just to verify nothing is causing a draw when all power is off.

My first ecm I belive had a battery loss of power which caused failure. my second ecm had the same but also the mother board was fried possibly from water when i washed the engine but the truck did run after. now its only injectors "short" they said this is a new file from the previous computer...
