Second attempt with t' 12V system. I accidentally fired it prematurely--momentary contact, but all 4 ignitors fired. Well, blow me down! Nay captured on this video, I later fired t' same ignitors again, with more pyrogen burnin' off. So, me bucko, A: t' system works great t' get power t' t' ignitors--no worries about clusters. and B: WATCH OUT! That fire button is trigger happy.
