Just for starters if I remember correctly. Disconnect the black/white wire under the seat. That should disable the kill switch. Check your coil has a good earth.
And just for information. The charging system has no influence on the ignition system

As above, do the coils have a good earth connection to the frame? I had this issue when fitting new Banshee Coils and fixed it by roughing up the earth connections with wet and dry.
