Ladies and gents I have come across a cure to fix the dreaded non operation of the electric aerial, however I need your help in order to identify the electronical component that needs to either be replaced or in my test case, bridged. Once this was done though, the aerial worked like it used to, going up and down properly, but since it was only a small piece of wire that was temporary I'd like to make a proper and lasting fix. please take a look at photo 1 and see if you can identify the diode or resistor thingy. The place piece is a wire i used to bridge the diode and which allows operation of the motor. This part is INSIDE the motor.
