I have a 15 month old Pro-Force digital golf trolley. It has a button for 10 yards 20 yards or 30 yards free run. When I start it up all 3 lights come on as does the digital display. I turn the control knob and when it passes from 0 to 1 there is a click from the control box but nothing else happens. The battery is fine. Does it need a new control box, and if so do you have one? It is silver and the label says :- S3D-C-USB-12V-22aA-CE There are some chinese characters with a 3 amongst them, then 07.02.2015 No. 78. It measures 102mm x 58mm x 36mm, with 3 cables coming out of it.

Please can you help/advise me?

Thinking about this scenario I would say the golf trolley control box is usually OK if you have all lights on and the golf trolley powered up as usual and you get a click from the control box on starting the speed control.  This click usually means the relay is working and sending the current toward the motor.  If it is not moving forward I would look towards the motor first and check it is working.  This can be done by unplugging the motor and connecting the end of the terminals to a 12volt battery source.  If it turns then the motor is OK.  A less conclusive method to test the motor is to smell it to find any burnt out smells although this doesn’t always mean the motor is defective or not, but if there is a burnt smell from the motor then most likely its accidentally been left running while being stopped i.e parked against a wall while at a low speed setting.

My trolley has stopped working and I think it may be a fault in the control box. Are any of the ones you stock for a Pro-Force trolley, please? The box has S3D-C-USB-12V-22aA-CE on the label, and the trolley has a button for 10, 20, & 30 yards free run.

It could be the control box but is there any power getting to the display panel now, if not I would first suggest the battery lead.

    My Proforce trolley lights up and it runs when you press the A,B and C, but does not show any sign of movement when you turn the knob to get the indicator to show 1 to 7 which does not show any number can you suggest any cure please.

      If the trolley works on A B and C but there is no number showing at all, not even 0, then it may be a fault in the handle circuit PCB. If there is a 0 lighting up in the display and it won’t move the numbers up or down then it may be the speed control switch itself.

      When putting the battery lead in and the 3 lights come on altogether by fault then this could be the controller box. It’s not clear if the handle circuit can also cause this. We usually recommend replacing these two components together at the same time. This keeps them compatible. Doing this also can stop one faulty component t breaking the other.

    Hello I have a pro force trolley and the pin either side that the wheel go onto that turns the wheels has broken, where can get 2 pins from to fit one on each side.

      Normally if there is a click from the controller as you try to move the trolley under power, then this usually means the controller is getting the signal and working (not always). So if the axle and motor are not moving, I would first check the trolley display is not switching off, as this would indicate a poor battery connection. Second to check the motor plug is connected to the controller ok.

      The electronics can vary quite a bit. Its all about matching up the handle control circuit with the controller unit (normally under the battery tray). If you cant find the controller or circuit to match your own. Then you can email us with some details or photos of your electronic components. IF the wiring is the same and you can’t find a match, then it will be best to replace the two spares; controller and handle circuit together, assuming your handle is one of the T or D shapes shown on various support pages throughout the website.

    I have a proforce electric trolley but I now find the battery is too big and heavy for me to manage , would I be able to obtain a smaller / lighter battery that would be compatible with the trolley ?

      We don’t supply batteries but it is possible to get a slim narrow battery of between 18Ah and 22Ah .
