My Pro Rider golf trolley speed control has stopped working, can you help. The trolley is switching on the power no faults and the display is showing as normal. The fault lies when I try to turn the speed of the trolley up or down it won’t work. The numbers are not moving. Sometimes if I wiggle the speed knob it moves the speed number but most of the time is does not work. The rest of the electric golf trolley is working fine. Please can you help me resolve this fault with the golf trolley as it is only just over 2 years old. Thanks, Bill
Answer to Electric Golf Trolley Speed Control Fault
The fault you describe very well sounds like the faults which happen to lots of electric golf trolleys. The knob which controls the speed is very easily damaged. This electric golf trolley speed control can sometimes get damaged when folding up or packing away somewhere like the car boot or cupboard or hut. This break occurs when the trolley speed switch knob is exposed and protruding then it can easily get bumped or knocked and cause damage inside the speed switch itself. It is not always visible like the photo below. This photo below the speed control switch has had a good knock sideways and it is easily noticed that the stem is out of perpendicular alignment. This causes the connector not to get a good all-round connection to the variable resistance plate it makes contact with. A complete component explanation can be found under a (speed control switch) potentiometer on Wikipedia.
Diagnose, Symptoms and Fault Finding
The symptoms for a break of the speed control switch are as follows;
- The electric golf trolley works and power comes on normally
- The battery charging and charger work as normal
- The display usually shows a number clearly but not always the correct number
- When trying to move or change the speed control switch of the golf trolley it doesn’t work correctly.
- The speed can not be adjusted and sticks at a certain number OR
- The golf trolley speed will work for a couple of numbers only and jump straight to high speed.
- The display shows the speed number and won’t show certain speed numbers
How to Fix a Golf Trolley Speed Control Fault
Fitting the new speed control switch is the reverse of the above all instructions that can be found on the support page at the speed control part. This fault is easily fixed by removing the knob and loosening the handle off the golf trolley and removing the speed control switch nut, then unplugging it from the circuit board. All is needed is a cross screwdriver and point nose pliers, spanner or socket and taking a couple of cross screws out, loosening the nut holding the switch in place and unplugging it from the handle circuit.
