The speed controller fan does not start up when the speed controller is switched on
• Check the connections between the two driving batteries and the speed controller.
• Check that both driving batteries are still fully charged.
• Only connect two driving batteries of the same build and type to the speed controller (same type, same build, same
capacity, same discharge rate).
• Either use two 2-cell LiPo driving batteries or two 6-cell NiMH driving batteries.
• If the vehicle reactls normally and only the fan is not working, check if the fan may be blocked due to leaves, dust or
dirt. Clean the fan. If required, replace the fan, since the speed controller will overheat quickly without the fan.
The vehicle stops while driving and the green LED flashes
• The speed controller is overheated and the overheating protection was activated. Stop driving and wait for the
speed controller to cool down sufficiently.
• Did you change the timing (see chapter 10. b), function #9)? if so, lower the value again.
