Voltage to coil

OK, back home, here is what I have. On the top post I have 2 dark blue wires. One looks like it is coming from the Ign. box on the firewall. The other one is coming from the big block of wires (sorry for the technical term). Then on the bottom post I have a brown wire, which also goes back to the big block on the firewall and then the wire going to the coil. Should also add that a wire is running from the positive side of the coil to the electric choke. Not sure if that matters at all.

Update: battery has 12.58 volts. Tested both dark blue wires with the key turned to ON position. One had no voltage, the other had 11.78. I connected the one that had voltage and reconnected the brown wire and the wire going to the coil. Still only got 4.67 volts on both the coil side wires.
