no power (electrical)

[real69ss]

I just replaced the starter in my 68', twice . The first time there must have been a crossed wire or a bare spot on the positive cable. The truck backfired, lost power , died and smoke poured out from under the passenger side fender. I popped the hood and the positive battery cable had melted.

I thought for sure I fried the starter, turns out the positive cable was the only casualty. Reconnected everything tried to start it up and nothing. Re-checked connections still nothing. Also no lights, parking, headlights or brake. broke out the test light:

Battery is good
Power from starter good
Power to the coil
Power at alternator
Power at fuse block
Power to ignition switch

Any ideas ?

Thank you!
