Mobility scooter repair help.
My father's scooter died whilst out and appeared to be battery loss of charge. Charged batteries and worked intermittently would reverse but not go forward. Commenced fault finding usual checks carried out fuses, brake engage lever, speed pots all appear to be fine and resistance adjusting with no dead spots. Key switch is switching back to main control box. 24V present at control box. Motor fine as dabbed supply to it to prove brake releasing and motor turning. Batteries are showing as 24.9V. Was getting a beep in maybe .5 sec intervals when trying to engage throttle but not getting anything at all. Really appreciate any help in this matter. Model in question is a Shoprider Deluxe think also similar to the Cordoba or 888 series.
Thanks in advance.
