I have a 1996 Club Car DS Power Drive Plus 48 volt with two solenoids and a 5 wire forward reverse rocker switch. Bought this cart several years ago under impression it needed batteries. Installed new batteries and no go. New solenoids still nothing. Sent the old T shape controller to a guy that rebuilds them and it worked perfect. Now, a couple years later, it will run fine for about 30 to 45 minutes, and quits going forward. Reverse is working fine. After a hour or so, it will go forward again. Solenoids click when in forward, but no go. I replaced them again to be sure. Replaced forward reverse switch. Still does the same. Any ideas?
