hello guys.
Joe, burned wire be careful. see the likely cause of what happened. not to burn new part, I use a light bulb in series 12V 100W during testing. if this light well, there are short, if it is off, the wiring is ok. see if there was some short, wear a wire to the frame and if there is some protection to the ignition circuit. I ride one of these cases and always start with fuse, 10. warms, increasing the fuse. a hug
