If you have a multimeter, you can verify that you are getting +12V on the black/red wire to the coil. (That's the thicker of the black wires with a reddish/purplish/brownish faded stripe that go to the coil; the thinner is black/purple and carries the tach signal from the (-) terminal.)

If you don't have a multimeter, you should pick one up. Even the cheap ones are good enough to help diagnose 914 electrical system problems. In the meantime, you can use an automotive light bulb or similar.

Is there any chance you hooked it up backwards? Or left the ignition on for a minute or more while troubleshooting? The Ignitor I is known to not deal with either of those very well. The Ignitor II is supposed to be better at coping with those.
