If your battery is charged enough to crank the engine, forget the alt/reg stuff at this time, it doesn't charge untill the engine is running. The battery is doing all the work. You need power to coil in start position and of course you need power in the run position. I am all for technology, but this is when old school points and condensor makes it easier to troubleshoot. Power into coil either from start position or run, if it finds a ground thru the points, the field builds up in the primary, points open, field collapses, induces spark in secondary and plug fires. Even tho the electronic stuff replaces the points and condensor, the principle is the same. Use a test light, on + side of coil the light is steady both in start and run position, on the -side the light has to blink or the field in the primary won't collapse inducing spark into the secondary and firing the plug.
