Controller and Circuits must be Compatible

One of the most important things to know when changing over any handle circuit or golf trolley controller is they must be compatible with each other.  This should be the first thing to check when replacing any of these components.  If in doubt contact me and I can confirm.  The online store has the controllers for sale and with each one is the option to purchase the correct handle circuit.  if this is done improperly then the golf trolley will not function or even power up.

A list below will show the components which should be aligned together.

Main Controller Box and Handle Circuits must be Compatible


S1G-12V-8-J-9 must have the square circuit



SIG-T2D3-J-12 must have the circuit D64186

New  Circuit sealed rubber.



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

Let me know if you need any other help or if I have got anything wrong.

    Is there a replacement part for controller PK3808 for the powakaddy sport? Where can I get the PK3808 controller?

    1. Can’t find one anywhere, even second hand they are getting rare. Does anyone know of an alternative or upgrade that can be used.

      1. Phil, if you would like to use the contact us form and give me as much details as possible. i.e. model, handle circuit, serial nos. etc.

      Thank you for the reply.
      Could you tell me what is the specific golf trolley controller that I need ?
      Thank you in anticipation

  3. I need to replace the controller on my pro rider golf trolley.
    how do I send the pic across to you?

      admin @

      I will be happy to look at it this Friday when I back at the office.

  4. Hi there. I need a new control pcb for my Hillman trolley. It’s an S2D type manufactured in 2014. Will the S3D type be compatible as I can’t seem to trace the original.
    Many thanks in anticipation.

    1. See (controller box S3D-G-USB-12V-22A must have the handle circuit D-62145 or D-61337). See above… if the handle and wire connection can take it, then it’s possible to switch over both controller and compatible handle circuit so as they work together.

    I have a powerbug trolley and it cuts out when in use, I’ve had a look at the E.C.U and only light one comes on.
    Will I need a new battery or a new E.C.U.

    Much obliged

  6. Can you help?
    I have just changed from a acid battery to a lithium. I purchased a new 3-pin to T-bar for it as well but as i turn it on via the control switch to No1 it takes off like a rocket ,It is all or nothing. its like it is on number 9, so much power..
    1-9 via the controller is all the same speed. Can you help. Will i need a new controller unit for use with a lithium and not acid battery?

    1. I am not sure if the battery issue is related I don’t see why. But this problem is almost certain to be a fault in the controller box and needs a new replacement. Check out the store to find the correct type. You should be able to read the serial model number for your trolley. Any questions just contact me on the contact page and I will run you through it all.

    1. I have a few brand new left in stock of the older Electric Golf Trolley Controller S3D-G-USB-12V-22A (now out of production). If you can let me know your handle circuit type I can usually know which controller works with it. The contact page has my email address where you can attach a photo if needed.
