I’m knee-deep in a rebuild of my 2003 Club Car DS and hitting a wall with some electrical and power issues. I’ve noticed slow performance, especially going uphill, and it’s vibrating like an old washing machine. I’m thinking it’s an electrical issue, maybe the cables or the solenoid? Has anyone tackled similar problems in their rebuild? Any advice on what to check or replace would be a huge help!
Response
I’ve been there with my own Club Car DS. It sounds like you might need to upgrade your cables or solenoid. I had a similar issue and switching to 4 AWG welding cables and a Curtis HD Solenoid made a world of difference. Also, don’t overlook your batteries; they can be the root of power issues too.
