Battery light stays on

Battery light in cluster of my dads 93 caprice wagon stays on. Has new battery and alternator and belt. Checked grounds and even changed battery terminals. Checked battery with volt meter and it has 12.8 volts with car off. When car is running it's got 14.7 volts. I think it's something in the wiring somewhere. Any advice will help

Check the grounds at the DS A pillar.

Churches grounds. Nothing broken. Cleaned the and sanded A pillar to be metal. I'm lost now. Checked all fuses. Checked voltage on the battery yesterday when the car off had 12.8 volts. Had 14.7 when it was running. Now today it died on my wife.

My Brother had a 93 RMW that developed an issue like that, when the car was off everything was fine, but once it was running the battery light would stay on and if he drove it too long it would die because it drained the battery, he figured it was a short in the harness by the firewall on the passenger side under the dash, but sold the car to someone for use in demo's before he could confirm it.


he also had issues with the gauges not working at times after this problem started.
