Help me out here. I have a 48v club car that my son says has shocked him when he touched the handle on the turn signal. If I put my meter's negative lead on the brake pedal, and the positive on the turn signall (chrome) housing it reads -48v. Of course reversing the leads shows +48v. However, grounding at the brake pedal and touching the aluminum trim, I do not get a reading. Any ideas where to start looking?
