So I woke up this morning, got ready for work like I do every day. Went out to warm my truck up and it started fine. Got to work and left my truck at the shop for 8 hrs and when I returned it started fine. I went to my girl friends house and left it for about 3-4 hrs and when I went out to start the truck it just clicked like it was a dead battery. So I had my girl friend come out side to jump my truck. Probably waited 20-30 mins and it very slowly started to crank but it would die out to the clicking noise of a dead battery. So I put a meter on it with the jumpers connected and it read 14v on both battery's. When I started it it jumped down to 6-8v. Then I took of the cables and read the battery's and it said 14v and it jumped down to 6-8v again. With the jumpers off I tried to start it and white smoke came up from behind the turbos and a weird smell sorta like a burning smell came with the smoke. I tried to start it again and it started but the crank was kinda like a whining noise. If I had to describe it it seemed like the started wasn't all the way there. I drove it home and tried to start it again and it just kept cranking with that whining noise. Someone pleas help me I'm out of options

 

I would unhook the batteries and check them individually. I believe you have a bad connection either at the batteries, ground connections on the block, or the starter. That's where I would start. Dropping to 6-8 volts after it starts tells me you may have a short in there somewhere. A bad connection can make the starter solenoid do funny things too.

 

You can unhook the positive cables and check the voltage between the batteries and engine.

 

how old are your batteries?

 

idk how old the battery's are I bought the truck about 2 months ago in Paoli PA

 

i will have to give that a try thank you
