Cadillac: No spark on 90 4.5 Seville, electrical schematics, loose term


Question
Hope you can help Tom. Getting E012(amongst others) w/no spark to any plugs. Distrib cap/rotor changed. New ign mod installed..no spark. But there was a loose term & after securing still no spark. Could that loose term have arc'd and taken out the mod?

Frustrated, went to salvage yard got another distrib in good condit, installed ign mod & started right up...for 2 secs and died. Back to no spark. Makes me feel when it started it knocked something out for some reason.

I am getting 10+V at batt connection to distrib while cranking. Getting 12+ on the tach side(cranking). Guess I'm going to have the modules retested again....any other tests, ideas?
