OK Back on the Holley Sniper install on 1974 440 Monaco police car after the WHO DAT collapse. Went full boat with Sniper, Hyperspark box, Hyperspark Dizzy, coil etc to head off any mating problems. Holley wants a clean 12volt "switched" with key source. I have a wiring diagram off the net and tried the fuse panel. Every circuit that shows no voltage with key off, shows 12 with key on. BUT when you go to starter cycle, voltage dives. So on to the engine room, blue wire to ballast block has 12v with key on but dives as well on start cycle. Brown on the other side of ballast shows none with key on and 12 on starter cycle. So do I tie them together? Wont there be a "speed of light" interrupt when I release the key after start? Any Sniper folks here? I don't want to fry anything as it is all new and aint cheap. Instruction say don't use starter circuit?????Phish

C body, made my on in tank mod for pump etc. Thanks
