I have got a power scooter (CTM HS686) for repair and experience a strange
phenomenum. Powering the scooter up works with an ordinary on/off keyswitch, but the scooter only powers up when the the switch is turned on and then off immediately. The scooter works fine then. To switch the scooter off one has to do the same; switch on and then off. When leaving the switch in the "on" position part of the functions won't work. Apparently the board now only needs a power pulse to activate, however the original keyswitch is of the ordinary on/off type. I have checked the board as good as I can, but cannot find anything wrong with it. Anybody any ideas how to approach this problem. Thanks Gerard |
