Fried Headlights..please help

[jpabberton]

Last night my headlights and radio surged and the whole truck shut down. I lost both headlights, running lights and one turn signal. I also blew the fuse to the radio. The dome lights do work though.

I rewired my radio yesterday and put in a new ignition key switch. A few months ago I put in new Alt/AC and engine wiring harnesses, new HEI ignition, new alternator and new voltage regulator. Haven't had any problems until this.

Would the HEI or voltage regulator have anything to do with this? Any suggestions would be appreciated.
