Hi was just goin through psu , just had a thought, part of the kit has 2 zeners 12v, 24v if by some reason i have replaced the zener in the wrong order ie  12v instead of 24v would this cause the psu to pulse and cause the pic to switch on and off,  its the only thing i can think of. its not like me to make a mistake, but these things happen from time to time
