No power while cranking

^^See above^^. There are two sources of ignition power FROM the ignition switch. IGN1 "run" IS ONLY HOT in "run." During cranking a special separate contact provides power direct to the coil + side of the ballast resistor--normally brown. This comes from IGN2, and like the start wire is ONLY hot in "crank" but they are actually separate from each other to prevent backfeed problems

Put your light/ meter on the coil+ With key "in run" you should have somewhere around 6--10V. Now crank engine using the key and watch the meter or light. You should not have full battery voltage, and at least 10.5 minimum, depending on battery charge
