ignition problems hard starting

Ok thanks. I did run a jumper wire from battery to positive and it fired right up. I'm not too smart when it comes to wiring so I didn't know what would cause this. What's an Ign 2 wire?

Mattax has your back on it with the diagrams.
Notice how in the ignition diagram Ign2 does not go through the ballast resistor, and Ignition does.

Ignition 2 gives the coil full 12v when cranking and the other goes through the ballast and drops the coil voltage to your 7.8 volt reading after it starts.
