Cat c15 help

I have a 2003 kwt600 with cat c-15. I am supposed to be bringing it to CAT for an overhaul. However, my luck is I'm sitting at truck stop and it will not turn on.

When I turn the key it just knocks. I had a new starter put in about a month ago when I was having the same issue. I used to jump it with a screw driver where the batteries are. I tried this with the new starter and it will not even turn it over, it just clicks.

I tried jumping with cables using another gentleman's Pete. No dice.

Does anyone know any tricks to turn this sucked on? I've tried everything I know. Also there IS fuel in both tanks.

Batteries are fairly new and are not dead. I tried wiggling the wires from the starter and followed them to the batteries and no go.

 

Pull start it

 

There is not enough room to do that =-/

 

have you tried thumping it with a hammer?

 

Hitting the starter with a hammer? If so yes I've tried. Is there something else to thump

 

pull the pin, and have the tow vehicle pull start ya bobtail, if ya got room to pull out of the place ya got room to pull start, you wont need a airport runway

 

jump it with the screwdriver at the starter

 

It has been sitting a few days. The air is bled out.

 

How does one do that? If I remember correctly when I did that it just sparked. Maybe I was touching the wrong thing?

 

The only other thing I have seen without changing parts is a ground to the starter. try adding another ground to the starter.
