I found some cheap spares that are out of the state I am going to try and have shipped up hear. I had to leave the truck where it was for the time being and will hopefully be getting a spare on it soon! thanks for the reply!

Afternoon everyone, I got myself in a bit of a pickle today while I was out trailing up Weston Pass with my 98 M1079. At some point while plowing through snow I cut the side wall of the driver front tire. I did not realize in time that the tire was leaking and once we noticed it was a bit to...

Gotcha was just curious I saw testing videos of some trucks that had the active suspension systems and they perform extremely well. Thanks for the reply!

Quick question I think belongs here. What trucks came with passive suspension vs active suspension? If you truck has Active suspension should you do after market shocks?

It is the old lever style switch. Not this new one.

Yes sir it is running!

These are the fluids that are available at the local Big R. I'm thinking I may just get the trans fluid.

Yes it does. I spent some time with it this morning because my transmission controller was also not come back on but I got that sorted for now and the truck will start.

Good morning everyone! I am currently running into and odd issue with my 98 M1079. I just got all the lights working on the truck by replacing some fuses and swapping a few relays yesterday and the truck was running fine however, this morning for some reason when I turn on the lights for the...

Got a quick question for you guys thought this would be the correct thread for it. How can you tell if a truck has already been switched to trans fluid? And is the original fluid in these really 15-40? I got my 98 M1079 running the other day and have been driving it around town. It is about 19f...

Thanks for the great info! Yesterday the temp outside was about 50f. The fan kicked on once for less than 30 seconds or so and did not come on again. I was testing out the mode function and driving in the local dirt church we have in leadville, climbing some hills and what not. This morning its...

Good morning everyone! Just got my 1998 M1079 running and was able to drive around a bit yesterday. Still have a few things to work out but could not be happier with how far I have gotten so far. I was wondering what kind of operating temps you guys see with your rigs? I believe that my temp...

This diagram helps out a bunch. I figured I could bypass the system just was not sure. I will be attempting this when I go back to work on the truck. When I first went out to work on the truck I only had 2 new batteries with me in hoping that the truck only needed the 24v system to start but I...

1998 M1079

Yup that picture you sent is definitely what is missing the smaller bridge is there but that larger PPD is missing. ( sorry i am not following the HMU and number set you listed in this message )

Yes this was on another truck at the pick up location that I snagged a picture of.

So I will be converting the electrical systems on this truck eventually but I need to get this thing started and out side of other electrical problems I may run into I want to diag these is a stock condition. If there is no replacement for this assembly then I guess I'll be converting it soon...

Hello everyone, I was reading through this thread and figured this would be the place to ask about a part that is missing on an M1079 I just purchased. With all your conversation about the 12v and 24v system on this truck I was hoping one of you may be able to point me in the right direction. I...

Unfortunately no. I was going with high expectations and was not able to make any head way. The truck was missing an extremely crucial part. Right behind the spare tire there is a voltage management box or field box that was missing. I was getting power up to the cab, but I could not get the...

Hey 98G, I got a hold of Robert! Thanks again for all your guys help I'll be in Abilene in about 3 hours. I have 2 batteries I hope to make work for the time being. He mentioned he won't be in Abilene till Thursday. Not sure if that's the case for you as well. I wish I would have seen the post...
