There are two tests you can perform at home that can give you an indication
whether your alternator is working properly. Try one or both of these before
spending any money on repairs:
• Try the headlight test. Turn your car headlights on while the car
is running. Do this outside so carbon monoxide gas buildup doesn't become a
problem. Press the accelerator while the car is in park. If the headlights
dim or get brighter when you press the accelerator, your alternator could be
bad. If the headlights remain the same, your alternator is probably fine. |
