Second attempt with t' 12V system. Blimey! I accidentally fired it prematurely--momentary contact, but all 4 ignitors fired. Nay captured on this video, I later fired t' same ignitors again, with more pyrogen burnin' off. Ya scallywag! So, arrr, 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.
