No spark after ingition module replacement

do you have a trigger solder gun? I think you can induce a voltage if you trigger the solder gun next to the pickup in the distributor. You should get a spark out of coil gapped to ground or a very faint high pitch buzz from the module but you have to have your ear to it, sort of a 'Bzzzt'. That is the electronic switching. If your old one is working, just repot it with some 2 part epoxy. The potting just keeps the moisture out and retards corrosion. Could even use silicone.
