I have built a diy charge controller from the schematic attached and it will not charge the battery. I have it connected to a 12v supply and when I short the header (instead of adding buttons) to force it to charge it only turns the dump led off and not the mosfet and it doesn't turn the charge led on. The blue and red wires go to the relay and the other two go to the battery.

Any ideas?


If it doesn't work hit it with a bigger hammer.
If it still doesn't work you probably shouldn't of hit it.
