    Help with kitchen receptacle

    I think Op needs to respond to my queries first given the connection arrangement used. A few good clear photos of the origin connections and the actual layout ( first , second, third) would clarify a lot. As it stands it appears point No.3 and the stove are on the one safety breaker along with...

    Help with kitchen receptacle

    Look where you initially tapped-in to the existing working power. I assume this was just to one point and your new points are in parrallel on one circuit from there. Your diagram is not decisive in that respect. Other than that black Active, white Neutral and bare conductor Earth. Take care...

    PWM on 12volt winch?

    Winch motor output is rather slow and high torque to begin with. Beats me why you need it any slower. If you must, run the rope a couple of times through a pulley block,makes much more sense.

    How to repair 3 boards not working. Auto spark voltmeter using neon bulb?

    I can only see one neon on the board (Rear side)....Which I Imagine would be reference to any spark signal. there are 3 LED's which I imagine you are referring to when you say "neon" Polarity of the spark does not come in to the equation as it is always the same. Polarity of the incoming power...

    So, go out and buy one suitable for an automobile. There are units with front and rear facing cameras, some with both in the same package for low cost, maybe $40.00 or less.

    Connecting two buck boost boards for a split supply?

    Possibly...if you keep the outputs totally isolated from everything else. It really depends on what your final application is and there may well be some regulation problems or other so far unseen. Why don't you just buy a split supply unit? Cannot understand why some will bend over backwards...
