1989 Toyota Corolla Base from North America
The coil went bad, which is common for the age of this vehicle, which is why the car will crank, yet not turn the engine over and fully start. After the replacement of the coil, the motor was steamed and it caused the alternator to fail in my best guess, which in turn overcharged the battery and ruined it as well.
Now the BRAKE and CHARGING WARNING LIGHTS stay on at all times while car is running. The car runs fine like this until the warning lights both begin to dim and then fade completely, and the car dies shortly thereafter.
I've replaced the back end of the alternator, and still both brake and charge lights remain on the dash panel. I'm going to replace the battery and see what happens next. If anyone has any suggestions for me, I would greatly appreciate the input.
The car has been extremely reliable til this point, and I hope to resolve this issue.
Would you buy another car from this manufacturer? Yes

Replace your whole alternator. That's the problem, it's not charging your battery or keeping the car running.

I have the same problem.
The brake and charge lights do not turn off.
I checked the alternator output, and it is 12v, but when I turn on the headlights and the heaters, it goes to about 11.3v and does not go back up.
Do you know what the problem is, and how I could fix it?
Could you email me back at firstname.lastname@example.org
Thanks a million!

Your output at the battery while running should be over 13.5V-14V with the lights off, and just over 13V with everything (lights etc.) turned on... 11.3V is a dead alternator and will kill the battery, since its output isn't enough to both run the cars electrical accessories and charge the battery... The alternator runs the entire electrical system, and the excess voltage charges the battery and keeps it charged.

If I am not mistaken, the voltage regulator is built in the alternator; you need to replace that alternator completely, the undercharging will also damage cells in your battery.
