Well we got working relays and breakers in all the right holes and it runs. Now to fix the hydraulic system for the spare and cab. Is there anything that needs to be engaged in the cab to run the system? Or push the pump button and set the controls to the item you want to move?

So the primer was firm. We just jumped the fuel shutoff solenoid and it fired right off. It is not getting power. The “stop” emergency light on the dash cluster stays on. Is there a low coolant switch? The coolant is super low.

Well it seems to be just bad dash relays and circuit breakers. I now have power to the dash and it will turn over good but won’t fire. I’m sure that’s from sitting for 3-4 years.

Th Thank you again for all the help everyone! Hopefully I can get up there again soon and check all these items.

It’s the idiot light panel in the top of the dash. The ctis was labeled and plugged in. I will suggest to unplug it if he wants me to come troubleshoot it again.

Is there a diagram available?

Thank you. The small display box on the dash “ idiot light” I guess was unplugged when he bought the truck. Does that mean something is possibly bypassed or does that not have anything to do with starting? We plugged it in but it did not light up.

Thank you! The spare is off and the rack is down so hopefully that will provide access. Also how big of a deal are the battery types? He has “regular pickup truck “ size batteries. Is that not goi mg to cut it? Do they have to be 24v or anything special?

Awesome, thank you. So what should my next be if I continue to troubleshoot this monster? Is any of the potentially affected wiring under the cab? He is also having trouble with the hydraulic system. He thinks it needs bled?

So I’m in the truck and I have no idiot lights, that panel was unplugged and the truck ran down when he bought it. No power at start inhibit k19 relay no power at cranking lockout relay 24. 12 and 24 volt at ignition relay K2. No power at voltage gauge. Power at ignition switch.

Thank you ! Hopefully we make progress tomorrow

Awesome, thank you ! I can try and have him text me a pic of a data plate to determine the year and model. The post states a 1998 M1079

Hi Everyone, I am heading to go try and help a fella get his m1079? Box type truck running. He states he has new batteries and some small wires for start interlock were rodent chewed but repaired. Still has a no start condition. Some electrical works and some doesn’t. He has been living in the...

Thank you!

Can anyone tell me if there are other gear ratios / gear sets available for these axles? What model are these axles? H110 or something along those lines?
