No power on D8 (1 reply)

I just connected a heated on D8 with the proper sensor.
I added heated support to the firmware

When I switch on the bed in Repeater host, the monitor shows full power, but when I measure the D8, no voltage is there.So the bed does not heat and the sensor confirms :S
(My extruder on D10 gives 11.9v)

Any clue's ?
