HEI Upgrade but No Spark (kinda)

Ian That is a nice S series as we call them in Australia. I am not an electrician but do not understand why you guys have so many wiring issues! I have run many distributers and different alternators and never had any problems. My MSD Ecoil was the worst. if battery voltage was not at least twelve volts it would not fire. The engine would turn over but not fire. tried to start it one morning and no spark. Put my fifty dollar chineseim dissy in and it fired straight away and never ran better. would start in half a revolution of the motor every time, something the MSD would not do. I recently put an Australian Ice ign system in it but have not drag raced it yet but with the Chinese dissy has run 11.4 @ 120 mph in my car. I did have a run on issue and a not charge till I reved it over 1500 revs when I put the internal regulated alternator on it but all that needed was a resister in the charge line to the amp meter and a diode where the ballast was to prevent back feed to the ign from the alternator. Pretty simple fixes!
