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.
