Please help, electrical issues

1997 Eddie Bauer Expedition V8 5.4 4x4 230,000 miles

I started having some strange electrical problems the other night. Battery gauge would drop to 8V and the radio would reset occasionally. Now the problem is worse and my gauge is dropping every time i hit the brakes or use my turn signal. Interior lights wont turn on when braking. All the electrical power from the accessories is being sapped every time i use the brakes. Battery and alternator seem good, havent tested it yet. Truck runs fine, only low power to accessories.

If you haven't tested them then why assume they're good?

No it doesn't start and run fine, you're having electrical issues. Stop assuming, it will lead you to make mistakes and replace parts that are good.

If you have significant voltage drops and electrical issues, the first things to suspect is either battery or alternator. Test them, don't assume they are good. They usually don't have any external indication of being bad.
