Not getting 12 volts to coil

You can easily access the connector of the ignition switch coming out of the column. That will tell you if it's in the switch, as you can access both halves of the connector (from the rear) and condemn or eliminate it. One wire will of course be the feed into the switch, and that comes from the welded splice. So if it's low there, it means it's back at either the ammeter or bulkhead connector

It can be difficult but not always impossible to access the passenger compartment side of the bulkhead connector. Consider removing the front seat. Some of us rig a "bench" outside the car to act as a "cot" to lay on up under the dash.

The bulkhead connector comes apart in sections. You would do well to pull it apart and inspect the terminals. The terminals all release and pull out of the connector. All you really need is some small needle nose and a quite small screwdriver

This thread has some good info on what to expect
