Speed control switch damaged

What is a Golf Trolley Speed Control Switch

The other name for the spare part is sometimes referred to as a potentiometer or pot original name being a reostat. This component acts as a speed control switch for a golf trolley by way of increasing the speed of the motor through a control stepping up of Amps

Damage to the Speed Control Switch

The golf trolley speed control switch is a common spare to go wrong.  It is nearly always damaged inadvertently from getting a knock on the speed knob.  This damaged the stem of the switch and causes it to loose connection either all the way through the speeds or partially through the speeds of the motor.

Note the stem of this damaged switch is leaning this becomes very loose through being knocked or bumped by an object or sometimes when packing away in the boot or similar.

Notice the movement in the stem of the switch from side to side.  This is usually caused by a blow to the speed switch rotary knob.  Sometimes when packing and folding away, it can get accidentally hit.  With the speed switch stem then unable to get a uniform connection when turning the knob stem around.  The connection at the potentiometer is interrupted and hence the speed numbers jump from low to high and don’t scroll smoothly through the speeds set by the golf trolley controller.

Testing and Fitting the Speed Switch

Testing and fixing the speed control switch is fairly easy by way of checking the trolley for erratic speed setting when increasing or decreasing the speed on the switch.  See support page for help. Depending on the model of golf trolley you have the determines how easy to replace the control switch is.  Fitting a new one is easy and tricky at the same time.

These models can be replaced by removing the back of the handle unplugging the switch and removing the nut on the outside of the handle by way of a spanner.

The round handles golf trolleys with the smaller knob are slightly more difficult as they require either a long socket or point nose pliers to remove the nut.

      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.

    I have a 2 year old Stowmatic GXT golf trolley. When I turn the speed control switch there is approx 2 sec delay and then the trolley wants to go at full speed even though the display is . When I try and alter the speed it doesnt react then it will be going at a snails pace or at full speed. I have changed the speed control button but it didnt have any effect. Do you think it is the electronic control board causing the problems?

      Ahh, This is a difficult one to say without the test bench. I would have though also it was the speed control switch. I have seen it being the handle PCB and also the controller. If the display is working as normal (no corruptions in any way) then I would think the controller is most likely to be causing this irregularity. To be honest it is very difficult to know. Of course you are welcome to send both the golf trolley handle circuit and controller to me and I will put them on the test bench and let you know, only charge is for the cost of the returning them to you, or in with a purchase if you end up buying a spare part. Please email me on admin @ electricgolftrolley.net and I will take you through the procedure to send them for testing.

      It is always difficult to determine exactly but in many occasions when the trolley jams on / off and at high speed and the speed control switch is working then the S1 controller (located under the battery tray) is faulty and needs replaced. A new controller will simply plug in place of the original. Available in the online store.

    My pro rider is jumping from speeds, it goes from 1,2,3,4,5 back to 0 then to 9, sounds like a speed control switch going by other comments?

      Yes this fits the Pro Force golf trolley. If the golf trolley speed jumps around when adjusting the speed knob then it is most likely the speed switch itself.

    Will this switch fit my pro-force trolley. If so will it fix the problem of jumping to top speed when set on a lower speed.

      jimmathieson Reply 24th July 2019 at 22:28

      Yes this fits the Pro Force golf trolley. If the speed numbers are difficult to adjust i.e. when turning up or down it doesn’t move then jumps when trying to increase speed to say 6 or 7 then this points to the speed control switch.

    The big button on the pro rider is it meant to stop and start the trolley like a Motocaddy or you’ve only got the A B and C setttings? Mine doesn’t could you possibly tell me what’s wrong with it?

      Jim Reply 5th September 2019 at 11:05

      Dan, there are a couple of models and vary only slightly over the years. The stop-start and on-off buttons are separate in the older models and the on/off is at the bottom of the handle controls. The other Pro Rider winged T handle model is on the right side and is only one button which is also the on/off like the Stowamatic golf trolley.

    I have a proforce golf trolley the speed control keeps cutting out especially after going over rough ground and off on button is difficult to re engage once I get it on I can control the tolley by only using the speed control knob and not using the on off switch and then it will cut again this is very frustrating and energy sapping do I need new control switch???

      Check this page for symptoms of the speed control knob first, but it seems it is more likely you have a connection problem either at the handle circuit or if all power is dropping the battery lead.

    I have an old hillbilly ,it will run for about thirty seconds then shut down I turn control knob back then start again for another thirty seconds, what could it be? please help.

      Sorry I don’t deal with Hillbilly golf trolleys. I would suggest it could be a poor connection at one of the connectors. Unplug and clean them with a spray of WD40 especially the battery leads.
