A frustrated customer brought this ‘stationary’ mobile golf trolley in to the workshop recently. He’d replaced the control unit along with the hand controller. The battery was also new, but the trolley wouldn’t respond to the controls.
A systematic test of the wiring revealed no problems and power was getting to the motor OK. However, with the unit switched on, every now and then, the motor would make a noise, a faint hum.
This indicated that the motor, a Lemac 65178-101, was trying to do something. A few searches online revealed that the Hillbilly Compact is no longer made and parts, including the motor, are hard to obtain for reasonable money, this is a shame as the unit is only just over 10 years old.
The customer likes this particular model due to its lightweight and compact folding ability. New ones are several hundred pounds and usually heavier.
Since the rest of this trolley is serviceable, it seemed sensible to have a go at a repair. With the motor removed, the cause of the fault became clear. The commutator was heavily blackened and scored and one of the brushes had burned away, probably due to the heavy weight the trolley had lugged around a golf course.
Being realistic about spend on parts, I thought it would be a good idea to order some replacement brushes from Amazon. These brushes will come from Hong Kong via Sourcingmap (an excellent source of hard to get parts) and I will let you all know how I get on with the repair. The motor’s back-plate is available online for just over £15 plus P&P, but I like to repair the problem, rather than waste components that still work.
More to come… I expect you can’t wait.
One the new brushes are fitted and the commutator cleaned, I hope the motor will spin once again.
