On my 12 volt conversion the hot side of the coil goes through the ignition switch. Switch off, no power to coil. I thought all the conversions were wired this way.

The problem is that the field circuit of the alternator feeds back through the system and keeps the coil energized. Where I work we commonly run the field excitation through an oil pressure switch, or you could use a double-pole single-throw switch, to switch the field current independently of the ignition and other "B+" circuits.
