That still sounds like a corrosion problem, it could be inside your battery cables, as it is a 79 that is a possibility, drag out your volt meter and start checking for voltage drops on your main circuits first, don't forget the little fuselinks that are connected on the starter solenoid along with the positive cable.

Absolutely, a catastrophic failure such as this is going to be where battery power comes in. Battery, battery cables, starter, starter solenoid, or the wiring down by the starter. Remember, accessories such as the headlights and horn are hot all the time on your '79 model. The ignition switch is not involved in those circuits. HTH. -Jim

on my 79 i just had the same problem. i had a mixture of problems. the first problem was i had grounding wires. i would check your wire going from your solenoid to your starter. i know that wouldnt fix the headlights but it may be part of the problem. the second thing i did was the battery wires. i took the red one that looked brand new and sliced it open only to find massive corrosion. it was eaten through even though it looked close to new. definitely check those if i were you
