Check you battery connections, sounds like a black corrosion problem.
Corrosion may be part of the problem, but what took place immediately may be a short somewhere that drained your battery dead. Re-check all your wiring for proper connections, frayed wiring or bear wires grounding the positive side. Was the distributor a straight original equipment replacement, or a fancy after market type. Make sure the wiring is correct per the instructions and compare it to the wiring of your old one. Did you disconnect your battery cables to replace the parts, if so, are they correctly attached and making contact with the battery terminals only?
If your bear wires are fine, check for bare wires also. :-(
