Fraser Foldaway2 Potentiometer / Switch

This is a replacement potentiometer / switch for the Fraser Foldaway2 electric golf trolley (as in pic 2 above). The Foldaway2 is the model which has 2 buttons and 2 green lights in the handle. The classic sysmtoms of a Fraser Foldaaway2 that requires a new potentiometer are: The trolley is cutting out intermitantly with the green light on the controller box flashing (located near the battery), and/or The potentiometer is very loose and/or is turning round without stopping.
