S1 controller NEW 9 speed

Golf trolley controller

Is there a fault with my golf trolley controller

I think from your support page my golf trolley controller is at fault.  When I switch the trolley on and gradually turn the control knob through the pace numbers, it seems the wheels are going at the same pace from 1 to 9 , very fast, I have had the wheels off the ground , if I put them down the trolley shoots off like a train, even on setting 1, can you please help me with this problem,  Many thanks

If the speed knob switch is showing it scrolling through the numbers smoothly but the golf trolley shoots off immediately at full speed, it is more likely to be the golf trolley controller unit rather than the circuit. IF the speed switch itself was faulty the trolley would either not start and not go up the numbers or jump numbers erratically. Normally if the handle circuit is faulty ( not always certain) it can show the numbers all wrong and sometimes not light up correctly. So my instinct is the main controller unit needs to be replaced. For the original style T-handle golf trolley like the ProRider, it is the S1 main controller unit. For the Stowamatic GXT, it normally is the S3D-G-USB-12V-22A controller unit, but some were fitted with the S1G-T2D3-J-12V always best to check the model numbers on the back.

Various makes and models of controllers.

Pro Rider T handle the original model

The new replacement controller is now black colour as shown below and has an upgrade to 9 speeds.


Stowamatic Controller

Stowamatic is slightly different. The GXT model (Green Handle) has a circuit PCB which has types as below.

Golf trolley controllers with their respective handle circuits.

The most common circuit for the T-handle trolleys like the Pro Rider golf trolley is the rectangular LED display to handle circuit with stop/start, distance buttons, and on/off buttons. These originally were built with a cellophane cover and small rubber caps for contact with the display cover. The newer upgraded circuits have a full rubber cover which keeps the dampness out and also replaces the rubber contact buttons as one piece.



This rectangular handle circuit only works with the S1… type controller and we sell the replacement upgraded new smaller black style. This upgraded golf trolley controller unit gives Nine speeds to your trolley without having to change the handle circuit (PCB).

There are other types of circuits that are for the S3… controller. As on the store items, these include the replaced
D-61337 for the D-62145 seen below.  

Older type controller S3D-G-USB-12V-22A must have the circuit D-62145 or D-61337


Newer type controller S1G-T2D3-12V-J is for the handle circuit D-64186 with complete rubber cover waterproofing the circuit.



Controller S1G-12V-8-J-9 is for the square circuit (* original T handle)


Controller SIG-T2D3-J-12 must have the circuit D64186 (Stowamatic, New style T Pro Rider, and Proforce, etc.)

Controller S3D-G-USB-12V-22A can have the circuit D-62145 or D-61337 sometimes the D64186.


Testing and fitting

These controllers are not the easiest test to determine if they are faulty.  Sometimes faulty ones can smell of an electrical burnt smell.  Other times it can look and seem fine, but cause various problems.  The support page describes various problems with golf trolley controllers and should help you look and test your golf trolley in different ways, this may help to shed light on some faults you may have.

  1. How to Remove the Controller
  2. Remove the large nut from the plug where the battery leads plugs in, this is located on top of the battery tray.
  3. Turn the golf trolley on its side to show the controller housing tray.
  4. Unscrew the four cross screws.
  5. Pull out the controller, unplug the motor cable connector, unplug the main wire cable connector.

How to replace the controller

  1. Plugin the new controller any of the two cables motor or main wire.  These connectors can not be fitted wrongly they are individual and also only fit the correct way around.
  2. Feed the battery plug-in socket through its hole in the battery tray from underneath and tighten the large nut on top.
  3. Replace the controller cover and screw in the 4 cross screws back into place.  These do not need to be too tight as they do hold well.

The cost of other makes of controllers can be very expensive.  Typical examples are over £60 plus post and packing. We keep our prices to the best they can be at under £30 as of Jan 19.

    1. You can either leave another comment or email and I will try to help. If you can give as much detail to the problem as possible this will help diagnose and fault find the golf trolley problems

  1. I would like to find a new controller for my old trolley. The problem is that the native controller has only eight speeds which are spaced too far apart. I would like closer speeds in the normal walking speed range, or better yet, continuous variation of speed.

    1. Pat, I don’t think any suit the Golf Motion 1 model but possibly have a controller for the Golf Motion 2 trolley. You will have to check the serial number on your controller and send me by the contact form. I should be able let you know.

  2. I have a euro pro golf trolley it starts then runs for a while then stops then goes sometimes I have push then it starts again when it stops turn the nob you can hear a click is it the controller the trolley is about 10 years old do you sell the controller I need what do you think

    1. If all the power leads and connections seem okay then it may be the controller especially if it clicks and nothing happens. If you can send me The serial number of the controller or if not a photo of the handle circuit display board, I should then know if I have a new controller which is compatible.

  3. Hi I have a Caddymatic battery is fine. No display when pushing the on / off button. Every thing is blank. The board is a D-64186 wedge shape. I changed the potentiometer about 2 years ago, Worked well. Trolly is about 5 years old it has the T handle. Have you got anything for a fix. Thanks

    1. Yes, it shouldn’t be too much of a problem. If you check (search box) for “golf trolley no power”. There are a few articles on this website explaining the best way to resolve this and spares which might be needed.

  4. I have an old hillman electric golf trolley the controller started smoking I disconnected the battery and pulled the connection from the motor to the controller this trolley is about 10years old can you supply me with a new controller

    1. I would recommend checking the controller for any model serial nos. I can usually let you know which are compatible from these numbers OR from the handle top circuit type.
