OK, here goes. To test the circut without wasting numerous fuses, plug in a headlamp bulb where fuse goes. Yes you will have to make an aparatus to adapt the headlamp and wires to where the fuse went. The load that the lamp has will keep the rest of the wires from "letting out their smoke" as we call it. If the headlamp is lighted, you have a short. When the bulb goes out, you have no short. Once Ifound this out, many shorts were found in short time. We call it the Ol' Ugly. Hook up the Ol" Ugly and start to move those wires around. When the light goes out. Look in the area of where you were when it did. Works every time if you have the patience. David
I need to make an "Ol' Ugly" and find the culprit of my identical problem with my K5 - everything is fine until I turn on the headlight switch then I blow that same fuse - this keeps me from driving the K5 at night and with daylight savings coming I need to get this problem fixed.

Am I correct that after I have Ol' Ugly hooked up, I turn the headlight switch on and because of the short the headlight will light up - then when I start wiggling the wires and Ol' Ugly goes out, that area of the wire is where the short is?

Just wanted to make sure I should have the headlight switch on when i start wiggling the wires.
