I'm having a problem with the lights on my 2011 Club Car Precedent. They started working off and on if I messed with the switch sometime they would work so ordered a new switch however that did not solve the problem. The in line fuse 15 amp is good couple questions can't find a ground any suggestions on where to look and if converter was bad is there away of testing reverse buzzer still works but I don't know if that is a 12 volt buzzer and is after converter or what also do bulbs come out the back or does the lens come off and if so how? thanks for any help
