Reconditioning your car battery (desulfator) Part 3 - everyone loves led's

The positive of the led (with a current limiting resistor inline) goes to the lead on the mosfet that goes to the positive rail in the schematic. The negative lead of the led goes to the center rail of the mosfet that then goes through the inductors to ground. (ALSO IGNORE THE FIRST TIME I TRY TO TELL WHICH ONE IS POSITIVE AND NEGATIVE, I ACCIDENTLY SAY POSITIVE TWICE,)
