Electronic ignition module trouble

Do some tests.

Measure coil POS and NEG voltage with key in "run." Coil + should be down quite a ways below battery, perhaps 6-10V. If it is "high" same as battery, then the box and or coil is not conducting, either bad connection, bad coil or bad box.

Coil NEG should be quite low perhaps 1 or 2 V. If it is quite high, 10-12V or so, the box is not pulling power through the coil.

If the coil is conducting, IE above voltages are OK, remove dist. connector. Take up engine harness side of connector, and tap the bare connector end against a ground, with a test gap rigged at the coil secondary. You should get one hot spark each time.
