Ben Sayers Golf Trolley Controller

Ben Sayers Golf Trolley Speed Control Fault

I have a Ben Sayers golf trolley. Yesterday it just switched off and after a while, I managed to get it to turn back on. It would only run using the A B or C function or run at full speed 9. I have tested the potentiometer which appears to be OK. Is this fault the control module? Look forward to your advice. Trolley just over a year old, picture attached.

Reading through my first thought was the speed switch but as soon as you stated it would only run by going straight to top speed, immediately I thought the controller box malfunction. This is a common fault of a control module rather than the handle circuit, my best guess would be the controller. We have three types, so in order to make sure you get the right one I have a list of Ben Sayers golf trolley spares from controllers to handle circuits depending on the model year and type. Plus see the photos of handle circuits attached.

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

With the rain, it is always worth checking the components are not damp and good dry out for a day or so, especially at the connections.  I would try a good squirt of WD40 around these connections, this will help and expel any damp or water.


Thank you for the prompt reply and advice. I played golf in torrential rain on Saturday and now suspect there may have been some water ingress as I stripped my trolley down on Sunday and removed all the components. On reassembly yesterday it appears to be working OK now. If the fault returns I will contact you to order a controller module. Many thanks again.

  1. I have a pro rider golf trolley.
    When I switch it on it all looks good.
    But when I put it into drive it seems to drain power and switch off,
    Any ideas will be welcome.

    1. Normally when the trolley is on and looks ok but when asked for speed it switches off completely- then this means it’s a connection. Probably a poor connection at the battery cable on either side. Either a clean up or replacement battery cable is needed.

  2. Hi hope you can help,my Ben Sayers all turns on but when I turn the speed control knob Im getting a clicking noise from Controller Unit(S1G-8-J12V-V)and wheels are not turning???
    Thanks Roy.

    1. Normally a click from the controller unit means it’s switching the current to the motor. So worth checking the motor itself with 12v supply and see if the motor turns on its own. If it turns from that separate feed, I would think a new controller unit is required.

  3. Hi, I’ve got a 2 year old Ben sayers electric lead battery golf trolley, when I turn it on it’s not going above 3 when I try to increase the speed it goes back to zero. Any help would be appreciated

    I have a Ben Sayers golf trolley yesterday while playing the trolly just switch off and pressing the on/off button the unit would not come back on . After disconnecting the battery all worked again for around 20 mins before switching off again and not coming back on . The battery had been fully charged before starting the round . This has happened a couple of times . How can I check the battery is charging correctly ( when charging the charge light starts red and turns green when charged .

    1. Yes, the battery should be OK if it starts charging with a red light and then goes green. It seems like a power connection problem like the battery cable lead most likely dirty of corroded making the connection poor.

  5. product code G5212. My trolley has on three occasions cut out half way around. When checking electrics underneath and moving cables it has started again without my being able to isolate any individual wire or connection. Everything is clean and dry and seems in perfect condition with firm connections up to sealed areas. All seems well from switch to the wiring area underneath. So obviously the problem is in that area underneath.

    1. Difficult to find but sometimes the only way to find it is to keep checking to narrow down if there or where the break is and of course it may just be the controller ready to go.

  6. During a round, the trolley switches off, if I then disconnect the battery and reconnect it will restart. When restarting the speed shows 9 and then fluctuates between 1 and 9 before settling down. However, this is happening many times during a round.

  7. Hi, I have a Nova P1D3 cart that looks like a stowamatic tolley. It has the green handle and uses the Ben Sayers SIG-12D3-J-2 with D64186 display board. The problem I’m having is increasing or decreasing the speed dial makes the display numbers flicker but settles down after about 2 seconds. When the desired number on the display is finally on, then the motor runs at the speed. Just wondering when the electronics will crash? Any help is greatly appreciated!

    1. Scott, in most cases the poor adjustment of speed control would be the speed control switch playing up. It runs on a resistance track which can get out of alignment causing poor points of contact on adjusting. I have in stock and hope this helps.

      1. Thanks Jim for the suggestion! By chance I had a spare display board that when swapped out the flicking stopped for now. If it doesn’t hold up I’ll get another speed controller. I tried testing the resistance between the terminals on the speed controller. Didn’t detect any wondering numbers during the increase/decrease of turning the knob.

        1. Yes it seems your symptoms were a bit more than just difficult to adjust speed, which does point to possible circuit or controller. The speed switch is the most common fault but reading your comment it makes it clearer that it was the display handle circuit. I’m glad to hear you had a display circuit that fixed it.

    1. I would always check the battery lead and its connection for debris damp annd also damage to sleeves inside 3 pin. Also other connectors – unplug and re-plug back in.

  8. My Stowamatic golf trolly display indicates “0” when switched on and when I adjust the knob the display stays on “0” and the trolley does not move.
    However, the A-B-C button drives the trolly as normal and indicates as such on the display.
    Can you advise how to fix the malfunction.

  9. I have a Ben Sayers Trolley, Lithium 16Ah battery. Fully charged battery but kept losing power (all lights out) particularly under heavier load i.e up hill. Have to unplug then re connect to get lights on again, would then run for short time but then would just go off. All connections clean as trolley has only been used approx 4 – 5 times and never in rain. Checked voltage on return home measured just over 15 volts. Tested running with no load for 40 mins all OK, but when loaded up, all lights goes off.

    1. Normally a poor connection only shows when under load so I guess a test with full power in heavy grass uphill and if it switches off, it could be the battery lead connection. If not a connection then I have seen a new controller sort this, but difficult to say.
