I have a Ben Sayers golf trolley. Yesterday it just switched off and after a while, I managed to get it to turn back on. It would only run using the A B or C function or run at full speed 9. I have tested the potentiometer which appears to be OK. Is this fault the control module? Look forward to your advice. Trolley just over a year old, picture attached.
Reading through my first thought was the speed switch but as soon as you stated it would only run by going straight to top speed, immediately I thought the controller box malfunction. This is a common fault of a control module rather than the handle circuit, my best guess would be the controller. We have three types, so in order to make sure you get the right one I have a list of Ben Sayers golf trolley spares from controllers to handle circuits depending on the model year and type. Plus see the photos of handle circuits attached.
SIG-T2D3-J-12 must have the circuit D64186


With the rain, it is always worth checking the components are not damp and good dry out for a day or so, especially at the connections. I would try a good squirt of WD40 around these connections, this will help and expel any damp or water.
Thank you for the prompt reply and advice. I played golf in torrential rain on Saturday and now suspect there may have been some water ingress as I stripped my trolley down on Sunday and removed all the components. On reassembly yesterday it appears to be working OK now. If the fault returns I will contact you to order a controller module. Many thanks again.
