I am using the one that steve ward designed based on the 4420 chip...It is 
under his MICROsstc...I did it identical to his...It worked beofre for 
me...COuld it be the breadboard?I diconnected the battery and then addedf 
the 12 volt reg in...Actual voltage was like 11.95volts out to the 
circuit...Once i swutched back to the battery, still nothing...Did i damage 
my chips?

At this point im blaming the breadboard since everything was fine when it 
was on a perfboard...I rebuilt the circuit and still no go...
