I need a schematic. I'm not going to waste my time doing this and find out it doesn't work and then the obvious, well you didn't build it right, yes?

You have done this yourself?

Luckily I live up on the side of a hill and my house is almost East-West aligned but I know exactly the direction it is pointed.

I'm assuming you mean a Wheatstone bridge?

Using this diagram, that I got from Wiki, you could simply replaced the R1, R2, R3, Rx, Vg, points A,B,C,D and tha battery to describe how this is supposed to work, where what part goes where or include a link to a schematic you know works.

No, I meant a rectifier bridge, as I previously stated.
