I have an 1981 toyota corolla I have changed the battery twice and the battery has died both times. I took it up to autozone and had them plug the car in to check the alternator and external voltage regulator. One of them is only pushing 10 volts when
Does the battery go dead while driving or while the car is off?Also have you had the alternator tested?

1981 Toyota Corolla I have an toyota corolla changed the battery twice and has died both times. Took it up to autozone had them plug car in check alternator external voltage regulator. One of them is only pushing 10 volts when the car should have 12 volts through it. The alternator and external voltage regulator where replaced in november 2011 and the terminal ends on the battery where changed on 1 14 2012 I though it might just be a bad ground. I did jump the car today and unplug the battery the alternator kept on running. I also checked the external voltage regulator and there doesn't seem to be anything faulty about it no burn marks anywhere on it and all the wires seem good. The car does not start now unless jumped and when it does getting running all lights dim, if you step on the brake they dim more, turn hear on dim even more, and the car just feels like it wants to die. I don't know what else it could be? There is a sensor light on I don't know if it is affecting it. Thanks, Justin.
It dies while the car has sat for a while and even with the battery on a charger and put back on it wont start. The dome light won't even come on in the car unless you take the ground wire from the charger and cause friction. Someone told me to take it back up to autozone and have them do a regulator bypass check. I dont know what else it could be though I mean everything is new but the wires at this point but there doesnt seem to be any burnt or messed up wires. Unless something was just faulty and went bad

So with the car idling what does the voltage read at the battery cables at the battery?

It reads 10 volts with it idling and my car is rated to push 12 volts
