Not getting 12 volts to coil

Thank you, Mattax for all your help. I've never seen most of your diagrams, which I need to study and combine with your insights. My whole assumption was a low voltage from the two-wired end of the ballast resistor meant my problem was bulkhead connector, splice, ammeter connections or the steering column switch. I've looked at wire # 16's cavity (red) male and female connections in the bulkhead connector and plan to do the same thing with cavity # 18 black wire, because they seem to be the basis for everything else related to low voltage at the ballast resistor, which would reflect as low voltage to the + coil. I lack knowledge of how the relevant wires flow and work together. After I try to clean the male/female # 18 wire, I'll reasseble. If it fails, then I'll have to decide if I want to learn how to install new connectors. The wires at the ammeter gauge look clean, but I've never looked at the splice. There seemed more current going into the bulkhead # 16 (I've cleaned the male probe) than coming out- see the female # 16 connector picture, so that's my hope. If that fails, maybe I'll pack up and move to Florida. Instrument Panel Barracuda.JPG Fuse box next to Bulkhead Connector.JPG
