Odd ignition and electrical problem

Hi , Thank you. I do have a service manual , and under the dash everything looks alright. So it's likely in the engine compartment wiring. I'll look there tomorrow.
An update; I found a burned wire in the harness behind the dash , all the insulation is melted off. It's black , and a fairly large gauge so I'm pretty sure this is the culprit. Prior to that , I unwrapped a good portion of the under hood wire , all that was okay.
