Sure, it will work. Wire positive (+) power to the positive side of the coil, negative side of the coil to the connection on the points. You also need a condensor hooked to either the points or the coil. Connect the wire from the condensor to the points connection or the negative side of the coil, and ground the body of the condensor.

Cars with point ignition systems were set up to start on 12 volts, and run on about 6 volts. This was done in various ways. Some had a resistor in the coil to cut down the voltage, (GM), some had a resistor wire going to the coil (Ford), and some had a separate ballast resistor mounted somewhere, usually on the firewall. (Dodge) Then the system was wired up so that when the engine was cranking to start, the coil got 12 volts, and when the engine was running, it only got about 6 volts. If you run 12 volts to the ignition system full time, it will burn up the points fairly quickly. What I would do is just run a 6 volt battery because it will start just fine. (You won't for example, be starting it with a damp ignition system in freezing winter conditions with dirty old spark plugs like you might in a car.) However, be sure to get a coil that does not have a built in resistor. One from an older Chrysler product, (Dodge, Plymouth) would be my choice. (Try something from around 1966 or 1968.)

Well, that was the long answer, but I hope it helps.
