My right headlight suddenly went dim, works but very dim, even on high beam. Parking light works fine. Changing bulbs has no effect. Plug is reading 24vdc. Left works fine. Suggestions?
You should have a yellow wire (+) which is low beam, a white (+) wire which is hi beam and a second (short) white wire (negative) which is the ground and should be fastened inside the headlight bucket behind the reflector.
Bad ground. All fixed. I should have checked it first. The Clack Bros. always say most electrical problems can be traced to a bad ground. Thanks for the help.
