Home Forums General Discussion Technical Questions Kone V3F16L Faults

I have checked all of the floor boards and all have green leds up.

I also have the 5v ok led in the CPU and tested it back to the map panel and I get voltage at the map panel but no car and hoistway leds.

I can only guess it is the CPU or map panel board. Surely it's not the ADO board as that doesn't have any serial connection.
