Marker lights keep blowing fuse.
So whenever i turn on my marker lights it blows the fuse and the marker lights go out and i checked the plug and a number of other things checked the wiring to the lights checked the third eye which was a little messed up so I pulled that off. And i replaced the marker lights with cheap led ones still no luck the only thing i can think of now is that a previous owner put led clearance lights on it and i have one nose marker light out. Checked the bulb in the nose and it was bad but didnt change the symptoms when changed. Checked grounds too. Im at a loss atm the last i have to check is trailer wiring stuff and clearance lights. Any other ideas would be greatly appreciated. Well nvm i figured it out for the most part.

If there's anything aftermarket, that would be a good place to check, because who knows what kind of idea the installer/modifier had of proper electrical work. Other than that it's a matter of disconnecting sections one at a time to see where the short goes away. This is best accomplished by removing the fuse that keeps blowing, the wiring a headlight bulb in its stead. Connect one headlight bulb lead to one side of fuse, and other lead to other side of fuse. A direct short will cause the light to shine brightly. When the short is removed, the light will go out.
