I have a 2014/15 model pro-force electric golf trolley. It works on the pre-set a,b,c fixed distances fine but doesn’t work on the Manual mode. The numbers still go up and down when the knob is turned but no movement. The screen seems fine, it’s had a new knob so does that mean it will need a new control module? Cheers
With you saying it has a new speed control switch then this makes it more difficult to say where the fault lies. Normally it would definitely indicate the problem lies with the speed control switch or its connections. The first task would be to make sure the speed switch is properly fitted; connections all connected properly and no dirt inside the connector plug and that the switch itself is working. So assuming the speed switch is working and connected OK the control box or LED handle circuit board (PCB) can cause some strange issues as does the control module. Although you can’t rule out the control box module completely, my best guess would be more to do with; firstly the golf trolley speed control switch then secondly the LED circuit board in the handle. Sorry I can’t be of more help, but without having tested the golf trolley, this would be my best diagnoses of the fault.
