I have told my story in other posts but I will sum it up here. On my 83 I had a problem passing smog and my charge/brake light were on. I replaced everything charge related,alt,reg., ect. so when I took it to an Independent Toyota mechanic he told me that it was the computers way of tripping the "check engine". I was running way rich and had other smog issues as well,so after a carb rebuild and various vacume switches the lights went off. They also come on and flicker when I pour SeaFoam down the carb. So if you get frustrated with the electrical look at the carb and emissions stuff. But start with the obvious first, Good luck.
