1972 dart - stopped running while at 50 mph ? no warning

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.

hmm , pretty much just burned up the wire in seconds , probably need a bigger wire . wait , maybe i went to the wrong terminal . i should sleep more .
