First brand new alt was the first thing i did but that wasnt it. Problem started when someone tried to put a different radio in the car, the new radio never worked and i discovered an electrical nightmare of disconnected and exposed wiring hiding behind the face plate. The car will run for about 3 or 4 days then faithfully the brake light will start to come on whem i depress the foot brake or use the turn signal. The car will start to idle roughly and eventually will fade until it won't start unless i jumpstart it or recharge the battery on a separate charger. Any ideas what this could be?

Hi percythomas,

The charging system is at fault and it could be due to :

1. Faulty alternator.
2. Connection between alternator and battery is open.

Did you test the charging rate, both at alternator and between battery posts?
