how do i know if i have a bad alternator isbad on my 2000 avalon ?
One way you could test is with a digital multi-meter set on DC volts, and see what the voltage is on the battery when the car is running. It should show 14.5 volts. Otherwise you can go to a shop and they can do a quick test on the charging system.
what is it doing or not doing??? yes as above...but might only show 12.8 untill you bring up the rpms to around 3000
Charging system should put out 14.5 volts even at an idle.
