I recently bought a replacement headlight for my 1971 cb350 after my last one burnt out. The light is the exact same as my old one, off of a 71 cb350 and same model # Stanley Sealed Beam printed on it. I have the replacement on the bike, connected just like the last one was, Green wire, blue wires, and white wire, but it only works when the key is turned to Park. The bike runs and rides but no headlight unless i turn the key to the "park" setting. I have both Hi & Lo beam on park, nothing in run. "I don't get it, Big Dan." any ideas greatly appreciated!
