Ken worth wiring grief

Does anybody know where I can get free wiring schematics for a 1997 T800 Kenworth? I am specifically looking for the running lights circuit. The circuit breaker keeps getting hot and tripping(only when moving). The relay does not act up at all. Also, how do I get to the back side of the fuse block? I think I can get to it from the engine compartment side, but the cove seems to be glued down real good. I just want to ask the question before I break something.... Thanks for any help you all can give.

 

I agree. Any idea where I can get a schematic? Thanks for the reply.

 

Thank you for the thought. I spent hours last night going through images and never did find one. That helped. God idea though....
Thanks for trying.

 

Thanks everybody for the great ideas. I am still at a loss... Today I actually decided to rewire from the firewall back to the plug and lights. It almost has to be a short to ground somewhere, right? Anyway, that didn't fix anything. With or without the trailer hooked up, it will do it. I even swapped from the low boy to the belly dump. So I am sue it is on the truck side, and I think I am pretty sure it's on the cab side of the firewall.....maby, lol. I have also swapped out the circuit breaker (twice). Sometimes withe truck just sitting there running, the darn thing won't heat up at all. But as soon as you start driving, it heats up and trips. Iw will cool down, work, and repeat the cycle. The relay and switch seem to work fine. The circuit breaker input seems to keep at around 12-ish volts. So I am guessing it is grounding out somewhere between the circuit breaker and the relay. Am I nuts? Am I missing something simple??? I really don't want to crack open that fuse block, but I don't know what else to do at this point...
