ProRider Speed Control Switch

Possible Fault with the ProRider speed control switch

I have a Pro-rider golf trolley that has developed a fault. When engaging the speed wheel the speed fluctuates and the speed display goes through from 5 to 7 then to 4 then to 2 then to 8. When engaging the distance mode i.e. “a,b.c” the trolley functions.  From reading, could it be my ProRider speed control switch?
When turning the speed wheel there is an audible click in the control box. I have contacted pro-rider to ascertain if they could diagnose the problem but they are more intent on me sending it to them for a service – which will take between 4 and 7 weeks.

Therefore, my question is; in your opinion, is the control box at fault or is it the speed pot and/or both? If that is so do you have compatible parts that I could purchase. On your website, I can see that you do provide parts for pro-rider so I hope you will be able to assist.

May I take this opportunity to thank you for any assistance you may be able to give me.

Many thanks for your photos, this helps. I believe the fault is most likely the ProRider speed control switch as in our store SKU102. When trying to adjust the speed turning it up or down causes the trolley speed to jump around. It the internal contact of this speed pot that stops working so it disconnects and reconnects in an inconsistent way.  See a full explanation of the speed control switch here.



Not Always the Speed Control

Some or no display on the readout. When turning the speed knob, no immediate reaction then slowly starts to move and react to speed knob control but unable to see what speed it’s at. The 10/20/30 button seems fine.

It is difficult to say what exactly the fault is. Normally if the numbers display stick when scrolling the speed switch, it can mean the ProRider golf trolley speed switch is at fault.  IF the display is corrupted it can either be the display circuit or controller. I have on occasion seen a wire connection cause something along with this type of fault. Circuits very rarely fail unless they have been knocked or dampness etc. has got to them, sometimes a wire short. I would go over the wiring, by wiggling and all connectors with WD40 to see if there is any difference while the trolley is on.  It is most likely the ProRider golf trolley controller (see below photos).  This is accessible underneath the golf trolley under the battery tray.  Held in place by four small cross crews and is connected to the main wire and also the motor.  Replacing this controller is a fairly easy job. I have the spare in stock and available on the store page.

    Hi, I bought my Pro Rider trolley in June 2017 and used it without problems for 2 seasons. Since 2019 it has been stored in its carry bag in my garden shed. Recently, I recharged the battery and cleaned the trolley in order to begin reusing it. Although the A, B & C button settings each started the trolley ok, the speed control knob wouldn’t change the digital speed number from zero and the trolley wouldn’t start. Initially, I wondered if maybe I’d got water into the controls during cleaning and so I left the trolley for a week in the hope that, if the electronics had got damp then it would dry out. Today, I tried it out again. This time, initially, the speed control switch worked fine. I tested it on all speed settings from 1 – 7, including stopping and starting. Then I tried the A, B & C button, which also worked fine for all three settings. However, when I went back to the speed control switch it wouldn’t move the speed setting above zero and the trolley wouldn’t start!
    Do you think that I need to replace the speed control switch, or is something else causing the problem?

      Your last paragraph: if the trolley wouldn’t move the motor at all NOT just by way of the speed control and the trolley display lights up, then it may be a fault in the controller (occasionally it can be the handle circuit). If no power at all – check out “no power section”

        Thanks for reply Jim. Think I may have mislead you with last paragraph. By “won’t move”, I meant that turning the speed controller button doesn’t change the zero digit and so the trolley doesn’t start. The A, B & C buttons always makes the trolley go. Does that change your advice?

          Alan, Yes, I’m certain it’s a new speed control switch needed. I’ve got one in stock available at the online store on this website.

    Hi I have been repairing a stowamatic for cousin. I fitted new control switch and got dial numbers working again. Then fitted new main control unit as not working. Now I have it working but the numbers showing are 8 but brighter when turning up, but still faint 8 still showing?

      This sounds like a small short or poor connection in the wires or connectors. I would go over each connector unplugging and if you have WD40 then a spray on each to help dispel the dampness and help with the connection.

    I have a handle like the above photo but my problem is that the “cover” over the stop/go switch has disintegrated so all I have is the interior switch exposed. The speed controls have also gone haywire and won’t stay at the speed I set. Any help please. Can I replace the handle?

      I do have the ProRider button cover for the switch buttons. I would make sure the handle is dried out for a day or so before powering it up. If you are still having problems come back to me via email (contact page) and I will be able to help.

    Hi i just fitted new control switch and board bought from you all the lights bar one come on but the motor cuts out when you turn the switch can you help

      We can establish the fault isn’t coming from the switch, which is usually the case. A test for this would show the trolley cutting out each time and even if you use the preset distance buttons. In this case I would check out “Fault Finder” page and 4th link down to No power in golf trolley shuts down.
