Can't imagine how you instaled the RS Rectifier without knowing how it's wired? Anyways, it's all at the top of this Electrical forum in the stickies, on the first page of the 'Radio Shack Rectifier Upgrade' by Caddy Kid:

Do yourself a favor while you're at it and go nuts meticulously cleaning ALL grounds including: light housings to frame, light bulb sockets & bulb base, ground wires to chassis [clean bare metal with a dab of grease], and clean all contacts inside wire connectors male/female.
