Going by memory here:

Primary circuit:
#15 is live (low voltage side)
#1 is switched ground (tach signal)   

You should have 0.5 - 0.8 (or 0.9) ohms across here

The HT circuit is between 1 and wire to distributer (#4?):  You should measure either ~2.5 - 3.5 Ohms or ~7 - 8ohms,  depending on the generation of your coil … one is green the other grey … I cannot remember which is which.

Make certain you disconnected the coil completely before measuring resistance!
