So I switched the crappy (plastic, yes PLASTIC) headlights outa my truck for some Sylvania SS (h4666). When I turned on the lights the 20A fuse marked PK blew! So I tryed a 25A and it blew too. Why would this happen? it there a possibility the headlight is causing this? I dont want to burn up the wiring. I didnt touch anything but the headlights and the corner lights. I have no parking lights or cluster lights or nothin! Please anyone got a simple fix? Or best way to trouble shoot this?

 

Ok, so I been tracing the circuit in the book, because its dark and rainy outside. I went and checked, and my headlights both hi/lo work and all my blinkers work both on the cluster and on the exterior, both fron and back. However, niether my cluster lights nor my licensplate or taillights work. Now I am assuming Im blowing a fuse because of a short, but where? on the diagram I am supposing it is the "brown" wire, but just a guess. I dont want to go through a million fuses trying to find this short, anyone have any ideas?

 

You know the fuse you blew as you wrote it in the title. I suspect that somehow you grounded out the park light circuit while replacing the headlight.

 

yah thata my thought too, Its light outside here now so I am going to go try to figure this out.

 

Ha Ha, It was totally a blinker wire snaged on the headlight mount, lol daylight is awsome!
