There should be a connection from the negative side of the coil to the points. The Tacho signal also attaches to the negative side of the coil. The positive side of the coil is connected via a ballast resistor to a 12v supply switched by the ignition switch.

If the starter operates, you can temporarily hot-wire it as follows to get it runnning.
Connect a wire from the battery positive terminal to the coil positive terminal.
Connect a wire from the Coil negative terminal to the distributor (points).
