your replies were very helpful
if i knew about your project earlier, i would have built yours...
btw the large inductor i'm using on the pcb it's 174uH do you think it's mandatory i should use 220uH
still i don't totally understand the way the circuit works...i guess less inductance then less powerful pulse
is sent to the battery...but what's the role of the second coil?
[EDIT]
wait...what do you mean neither of these pulses will do much in desulfating?
as you said earlier it is suppose a good battery absorbs the pulse so the voltage
is less right?!
