Check for 12 volts at the terminal that is closest to the firewall. the accel coil connection is marker Batt + (I also have one on my 69) Although it may read as low as 9 volts (if resistance wire was used (original point resistor wire). Mine reads 10v and operates fine (one day i'll replace it w/ normal copper wire). Make sure the module clip connector is attached (closest to the distributor cap itself). If all checks out, you may want to remove the cap and make sure the high voltage contact button on the coil base (from rotor cap)is not missiing or broke. Also inspect the wire as the enter into the distibutor base as they (due to vac adv movement) may have wore the insulation and shorted to gnd, or broke one of the 4 wires (open ckt).
hope it helps A no spark condition is really easy to find and correct on these old cars, you'll find it for sure!
