when you say , direct hot wire , do you mean run a wire between the positive battery terminal to the coil positive terminal ?

Yes, that is Hot Wiring the Coil.

Don't leave it hooked up for a long time as it will heat up the coil with the full 12 volts. But you can try and start it to get it running.
