Im new to this site but Ive worked on semis for several years and owned a few. I had a 85 pete with a 400 big cam And I had the same prob once. It was just the turbo. It only cost about $800 and about an hour of work.

 

Update please.

 

No boost, check turbo and related tubes for damage .

 

Sorry its been so long. Just busy with working full time, going to school full time and having step kids.

Anyways, still haven't gotten to go check the truck out again. Like I said I live 2 1/2 hours away. I forgot to mention before but I checked the oil in it. Its nasty and sludgey like tar and it has a diesel smell to it. Been talking to instructors here at lincoln tech and I've also been told to check the pump and the injectors.

But my biggest problem is just making the time to go up and look at it.

Does anyone know this truck is 12v or 24v? How many cranking amps am I going to need to get it to crank over??

I'm currently working for NTB so I have access to used batteries now. See a lot of batteries with 500 cca get replaced because the tester says they are sulfated.

Speaking of batteries I heard there is a way to refurbish batteries. Anyone know anything about that??? I have an old Caterpillar battery and one truck battery. If I take the Cat battery and the truck battery and run them in series will that be enough cranking amps?

The Cat battery has about 1000 amps.

I'm itching to get back up there soon. I have a battery charger with a jump start mode that could add in an extra 2-3 hundred amps. I'm probably getting a little carried away on all of this but I've had nothing but time to think about it.

 

Once batteries loose charge over night, and they still have water and there isn't any shorts in the vehicle. Usually means they are toast.

BTW, you make it out to your truck??

 

Going to close this down for now. You can reopen the thread to update.
