Ignition start / run question

Sounds like you don't have "ign1" and "ign2" jumpered together

IGN1 is the "run" ignition line comes from the ignition switch, through the bulkhead, and supplies underhood loads, ignition, VR, alternator field, some smog devices

THIS POWER GOES DEAD during cranking

Orginally, IGN2 came from the switch (usually brown) through the bulkhead, and to the coil+ side of the ballast. THAT IS THE ONLY source of ignition power during cranking

Both IGN2 and the "start" wire are hot during cranking, but the come from different switch contacts.
