I recently replaced a battery on an 06 with 140K; it was having trouble starting in the cold. For about two months everything has been ok.
Today I went to start it up and it wouldn’t crank. I got the battery charger out and after a few minutes of charging , got enough juice to start up.
Drove the car for 30-45 minutes with no issues and no dash lights.
I inspected under the hood, not thoroughly because it’s cold and noticed that there is corrosion around the positive battery terminal. This is recent as when I replaced the battery I made sure all the terminals were clean. Doing a bit of research I understand that this is a sign of overcharging and that it could be the alternator itself or maybe just a voltage regulator.
Scanning through websites like RockAuto and Toyota/Lexus pets dealers I can’t see that voltage regulators are sold separately. Does anyone know? I’d prefer to start replacing that before the whole alternator.
I haven’t yet taken the multimeter to actually check the voltage to confirm overcharging.
