Hi all,well,l have progressed the B4 to the gear install stage,l have just fitted my new RB-20 redundancy bus,but it seems like l have a problem with it,at first all seemed fine,my u/c and doors were going up and down in fine style....then my tx started shouting at me,warning power overload-servo overload,which it kept repeating.....this got my attention,it not being something l had set up or even heard before

,investigation followed,but all seems to be fine,this warning is produced even after l pulled all the servo plugs from the rb-20

,l also removed the back up power lead so l know its not an overload,the fact that the warning happens even when no servos are connected is worrying

,does anyone have any ideas as to the cause

,the instruction sheet states that the rb 20 does have overload protection on each channel,but l cant see why its activating with nothing but the power lead plugged in and only supplying 6 volts...maybe my rb-20 is faulty

any frsky gurus out there have any suggestions
