      No I don’t believe this is the correct switch for any of the Motocaddy golf trolleys.

      Many of the switches are standard fitting like this one. I am not sure of your specific model of trolley, so the best thing to do would be to check the connections with our photos. Ours is a 10K pot. Hope this helps, JM

    I have replaced my Pro rider electric golf trolley motor, but when I switch ON all it wants to do is go at full speed. Even when I adjust speed control knob it just stays at full speed. Could you please point me in the right direction as to what I may need to replace.

      If your display LED is lighting up normally then chances are it is likely to be the S1 controller box (under the battery tray) which has malfunctioned and not the handle’s circuit board (PCB). We supply the newer upgraded 9 speed S1 controller which will fit perfectly in place of your original. It has 3 separate / different plug-in connectors, this keeps it simple to replace.
