  2. Closed: Re: Mains leaking currents causing problems in my house

    Eagle1109, do you have any idea what or where the gray wires go to. They look like they pass through the box without connecting to anything.

    I believe the component bottom left is a "resistive humidity sensor". Looks almost identical to this one.

    1. In your 2 videos is the motor connected directly to a 12 volt supply. Or is there another controller. You only show motor so we have no way of knowing.

    2. If my drawings are correct then the...

    The reason I included probe placement in diagram was because there seemed to be a polarity to follow. If I reversed one probe the angle was much greater and flipped if I'm not mistaken. So I'm not...

    I'm guessing the 2400 mah rating for AA is one battery. Fixits clock uses two AA batteries. Would this not be 4800 mah capacity.

    But a very poor one it seems. I took some measurements with a 5.1 ohm resistor as load.

    Applied voltage primary - 3.27 volts @ 2.66 amps
    Secondary voltage - 3 volts @ .588 amps

    That is what I thought may have caused motor to slow. The wheel was only supported on one side by motor shaft. Forcing the precession must have put a great deal of stress on bushings/bearings and...

    You might consider 5 amp fuse between battery and controller. Then lower rated fuse from controller to load as wwfeldman suggested.
