Re your alternator and CIS: If your 1976 car still has the CIS fuel injection, it does not depend on a steady voltage to work. The only electrical parts of the CIS in your car are used during cold start and warm up. Once the engine has warmed up, they do not have any effect.

It's still possible that a bad alternator could affect the CDI ignition. Check it with a voltmeter. If it produces about steady 14v, then go back to troubleshooting the CDI ignition. Do you have a voltmeter in your gauges? If not, get one that plugs into your cigarette lighter socket to monitor voltage while you are driving.
