need help from anyone that has experience with one of these chairs.. problem...the charge light will only show one charge strip even after an overnight connection to the charger.. just the one green strip on the indicator.. after running/ using the chair a short time. the indicator light goes off... it is posible that the batteries may not be accepting a full charge, removing the battery and checking it it seems to be fully charged..how many volts should it show disconnected from the chair I would guess 12 v. or is the problem in the indicator light.. thanks PS I guess you can tell, I am not a electric expert
