My wife has an 88 Toyota Corolla (4af, I think) and the brake and battey light came on at the same time. Her car was on and all of a sudden, all the accessories wanted to turn off.
We turned the car off, and it would not start again. I assumed the problem was the alt. since it has never been changed, so I replaced it with a new one. The car has started up fine ever since,.. but the brake and batt. light are still on. The brake res. is full just above the max line.
Should I change the battery??? When I used a voltmeter,.. it read 13v's while off,.. and 14v's while on. I turned the headlights on and the volts dipped and went back up fine.
Is the battery suppose to measure 13 volts while off?? I thought it was suppose to measure 12v's???
Could this be the problem???
