My oldie 84, with 86K, 4 cyl, 22R, first year of the electronic controled 4 spd auto, has a prob with the Charge light and Brake light both staying on after the car is started. I am getting regular battery voltage of about 11.5 to 12.8 volts all the time. The voltage at the Altenator output is the same, all the time. My son, says that the alternator always should be putting out 13.5 to 14.5 volts when the car is running. I said that the regulator will turn off or lower the output from the alt when batt is charged. QUESTION: Does the alt reduce it's output voltage wise, when the batt is charged? or does the voltage at the output terminal always stay at 14 volts roughly? Thanks for reading. TakeOut |

Replying to: takeout (Feb 24, 2005 2:44 pm) That way, you'll know for sure. (My bet is the alternator is going bad but I've seen alternators mess up when the battery is going bad....so the check will let you know.) Good Luck! Boo
