Overcharging
Looks to be an issue between Female and male connector specifically the large red main power wire. Had the problem about 8 years ago where it was sporadic about turning over and I replaced the ignition switch and it fired right up (thought problem solved) than sat in the garage until I got a wild hair to start working on it again. Since I replaced the female side that goes to the column I’m assuming it’s the male side that goes to the main harness (if you move the red wire just right it dies)
It did drop charge at alt to 14.78 volts
And battery voltage was 14.11
