MAZ537, I haven't gotten this figured out yet. I now have it worse as there is no 12V in the cab at all. I can't find where I'm supposed to be getting the 12V from to the fuse block. The purple white to the starter relay has no power, the yellow wire to the ignition switch has no power...

No, I fixed it back in 2018 but forgot to let everyone know.

Hey all, i just noticed I didn't post the results of my troubleshooting. Turns out there was a plastic in line filter tucked under the cab. It was collapsed and restricting the fuel flow. When the heat from the engine exhaust and the pressure from the pump suction worked together I'm sure...

I recently rebuilt my 6.2 due to some cylinder problems. The truck started perfectly prior to me removing it. Now I have no glow plug relay control and there is 24v to the input side and no voltage to the relay solenoid when I activate the push button. I am getting the wait light to...

Thank you all for the ideas and solutions.

Thanks, that is what I expected.

The no. 2 generator belt hits the lower radiator hose even though the belt is tensioned. Is there a shield out there that I can mount on the hose to keep it from getting cut?

So one time, when I pushed on instead of pulling over, by the time I hit about 40 miles it was spitting out smoke but it was faint and white or blue/white. I didn't lose coolant and was just a bit low on the engine oil but never got that a second time.

Thanks Lizard Dog, I just found a drop on the mechanical pump today. I'll check tightness tomorrow then chase the lines to look for other areas that might be wet.

Iceman, my truck doesn't go anywhere near that high of rpm except when revved in neutral 1800 rpm=45 mph, 2100 rpm=55mph, 2400 rpm=65 mph and 2500-2600 rpm=70mph normally with about an inch pedal left till floored.

I don't run 70 often and when I do it's not for long stretches. My truck at 70 on 35 inch tires runs 2500-2600 rpm so I'm not pushing it to hard.

Transmission checked good! I have a buddy who owns a transmission shop and he looked at it today. No leaks, presure at the module, no overheating noticeable when touching the transmission cooler lines. Oil is pink/red with no burnt smell.

I have a loss of power when my 6.2 M1008 reaches operating temperatures. I don't lose low end performance. I have driven it at speeds of 65-70 mph with plenty of pedal remaining but once it gets around 160 degrees I feel the truck get sluggish. If I stop and restart the truck it idles and...

Thanks dependable, still learning how to navigate and search these forums.

I was on my maiden road trip with a 1986 M1008 when the wipers quit working in the rain. The voltmeter was in the mid-yellow but moved into the red after a few minutes. When I got it home I pulled the batteries, they tested good and were recharged. The alternators were pulled and they too...

No data plate on the door post but I do have the four holes where it used to be.:D I looked at the transfer case and it is a NP208 and there are no helper springs. M1008 it is I guess. As I mentioned in my original post this truck is modified and I'm about to put heavier springs on the rear...

I found a 1986 D30 but no data plate to tell what variance it was. Where can I find data to determine what variant I have?
