Hello , I don't have a manual and am in need of testing values so I can pin point the issue of no spark on my 72 ext 340 free air with twin points...any help would be great thank you.

the motor is on my bench...fresh rebuild. I removed the external ignition coils and with my digital volt meter I can get over one volt on each pair of wires going to each coil when pulled over and I can watch the volt slowly decay as each condenser slowly goes back to mv. when I do a ohms check on the plug wire to coil signal wire I have nothing on either....I suspect 2 bad coils ....sound correct ? thanks!!!
