Polarity isn't dependent on voltage. The coil will work either way although for efficiency and best spark, the wire from coil to distributor should be on the terminal you have grounded -- if your new battery setup is now neg ground, then (-) side of coil should connect to dist.

Did you install a ballast resistor in the wire from ign sw to feed side of coil or use a new coil for 12v with internal resistor.
