I just bought a project bike from a friend and I’m super stoked about it. I’m having a hard time getting the rectifier to sit flat in its position to the frame. It’s sort of leans up on the left side frame about 1/8th to a quarter inch off of its flat point. The seat isn’t mating up like it aught to. Has anyone seen this issue before is there a proper rectifier I should be using? Also is the rectifier supposed to spark when it makes contact with the frame?
