Inherited a 2003 club car. I believe it is 48v, but I am not sure. The guy that gave it to me told me that he replaced the solenoid and took apart the f/r switch thinking that those were the problem. I think I got the f/r switch back together, I get a buzzing noise when in reverse. I also replaced a battery cable that was in bad shape. However I am still going no where as the cart won't move. Please help.
