NO You are "darn near" clear up to 11v at the battery cranking. Two volts drop between the power into the switch and the coil is a fair amount of drop. You should be able to see where this is happening. Measure at the ign switch connector and try to probe both interior and engine bay side of bulkhead connector. "Wiggle test" the bulkhead connector and ignition switch connector see if that drop changes.
