Default Electrical / Car Dying Issue

Hello,

'65 GTO, with 455, '65 Tri-Power, MSD Dizzy, 6AL box, blaster 2 coil.

I had an electrical short that resulted in the car dying as I backed out of the driveway. There was smoke emanating from under the hood after a few failed restarts and I found a frayed wire had shorted, the current jumped to another wire and they melted together. See the first photo. All fixed and I have driven the car twice.

Today, it died on me twice, but I was eventually able to limp home.

I pulled the main coil to dizzy wire and noticed some minor melt. See the second photo.

I've pulled the coil and measured ohms. Primary 0.7 - 0.8 ohms. Secondary 5,800 ohms.

Any opinions? I have very little experience with electrical. The wiring is 25 years old. I'm thinking of replacing the entire wiring harness and making everything nice.
