Ignition woes

I did not know about 'shorts', and when my bulkhead connectors looked good, and the low voltage was showing up on the brown ballast resistor bypass wire under cranking, I was led to the ignition switch, thinking there was rust/resistance inside.
I did not know that the quality of lights and accessory leads as shorts within those wires, coming off the main splice could affect the Ign 2 start circuit. Also, my starter did not have bad voltage drop, grounds looked good, so I focused on the ignition switch wires under the dash. You've helped me a lot. When voltage at the ammeter connections was close to battery voltage and the same low voltage was showing up at the red J3 and Accessory connectors, I thought 'bad splice.'
