    Open the hood, on the firewall near the steering column is what looks like a spark plug boot, unplug it clean good coat with dielectric grease and plug it back in.

    Sounds like you may have a short grounding out somewhere. I would look real close at that particular circuit first, then go beyond to all wirings where they cross over metal or go through tough bends, looking for exposed wire touching metal

    Just a thought
     
    Aron Thanks this.

    Well, if you have a cummins you can get the engine side diagram from cumminsquickserve.com

    For the Kenworth, idk. Dealerships @ a price, unless you got helpful people on the inside. Other than that, maybe you can pick one up searching long and far through google, yahoo, bing etc
