Usually there should only be 12 volts (relative to ground) on the coils high input (NOT to distributor) terminal since the other terminal wires to the distributors points which are usually closed thereby at ground potential. If you put a test light on the coils low output to distributor terminal and the engine is cranked over it should flash on (points open) and off (poinst closed). If it never goes off the points arent closing or very badly burned,,,,If it never is on, the condensor may be dead shorted or theres a short in teh distributor like the input stud/terminal.
Even if it has an elec switch it does the same as points, it closes to conduct coil current then opens momentarily to fire the coil.
If its an elec ignition much of my test procedure still applies, the points are just replaced by a solid state switch
