Re: Cheap driver PCB turns black?

update: got the circuit working now however an odd situation occurs where the voltage aross the 1 ohm resistor is fluctuating: starts off .12 amps then slowly inclines to .20 then bounces between .2 and .186 im assuming one of my diodes is not workimg properly. is this usually the case?
