its a stock 77 cb550k. i just charged the battery and let it sit for a few hours, it check out at 12.55 volts. i put the battery in the bike turn the ignition on but not running and the voltage starts at 12.55 v and counts down slowly. i turn the left blinker on and it works perfect, front and rear bulb light and flash accordingly. as soon as i turn it to the right blinker the main 15 amp fuse blows. i recently went through almost every wire and clean them. i have no loose wires that i know of. any suggestions on where to start with this?
also, is the rear brake light housing sealed? i didnt want to come off when i tried removing it and i didnt want to crack it.
