[QUOTE="vlammie, post: 501504, member: 270173"] Hi Llew My SMPS broke down again. This time C10 shows a hard shortage. It blow the fuse. Lucky i have a spare SMPS now. Replaced it but then discoverd that the motor was not rotating in 1 direction. I got a "motor error". After investigation i discovered that a trace on the PCB runs close the the metal mounting stud inside the receiver. This trace is running from the connecter to one of the relais. This trace is then shorted to ground and the motor is not moving anymore. I have taking of a part of the stud and this solved the issue. Furthermore I think the east relay is drawn in the "activated" position instead of in the resting position. During the initialisation fase of the receiver (ON) both relais are activated for a short time, bringing both M1 and M2 to 36 Vdc. This results on no movement of the motor. Normal only the east or west relais will be activated, switching eithere M1 or M2 to 36 Vdc and leaving the opposite connected to ground. [/QUOTE]
