I'll keep it short, I noticed flickering lights just before my stock battery failed. I put in a new battery, flickering continues. I replaced ground cable, no help. Now I'm thinking bad voltage regulator so I replace alternator, no help. I removed every light bulb thinking, maybe a short in the wires that I've moved in the past. No help. Now a new issue, it starts with a voltage reading of 13.2v then 30 secs or so it jumps to 15.6v. it used to jump to 14.8v. l scanned for codes, no codes registered. Anyone see this?
