Now what's wrong with this thing?
1994 ezgo medalist. Two issues. Has a slight "clunky" noise when coasting it in yard unless I am Riding brakes or accelerating. Also and the biggest issue, Don't know if this is normal performance for a 36 volt cart but it is sluggish poking around my somewhat hilly yard. (First cart so I have no point of reference as to cart performance). Cart will stop running after a few minutes and it sounds like the motor is running but it goes nowhere. Replaced with a new solonoid and same issue. Bad controller? Bad motor? Forward and reverse selector? Has a new battery pack, new brushes and insulators. What goes bad in a controller? Can I replace it's components? Help appreciated!

Also when I let it rest for a while. It is ok and runs " normal" for a while.

Remove any hubcaps so you can see the castle nuts holding the hub on the axle. If the nut is spinning and the wheel isn't, the splines are stripped. Only takes one stripped hub to keep cart from moving, but replace both sides. Also, there are splines at both ends of axles and another set between motor and differential. ----------- However, running normally after a few minutes rest sounds like controller overheating. What diameter tires are you running? |

Driving slow and going uphill draws more amps and causes the controller to get hotter. Shutting down periodically and running normally a few minutes later is a symptom of the controller going into over temperature shutdown. But, if that was happening, the motor would not be running. The motor running when cart isn't moving is a symptom of a mechanical disconnect someplace between the motor and where rubber meets road. So there are conflicting symptoms. |
