I just spent $500plus dollars for a tune up and to replace the control module. Now my battery light is on, they tested the alternator, said it tested fine, but I should replace it anyway because it will probably go out unexpectedly, in a week or a month or. And of course theres another $300plus. Do you agree, or could it be something else, possibly the battery itself. Model is gl and has 3.0 litre engine. It is now wednesday, I took the car into another shop they did a charging system test for $29.99 and determined the battery is fine but the alternator is in "overcharge condition. Max output is 254 amp" what does that mean?Is it o.K. To keep driving?Should I just pay the $300plus and have a new alternator installed?
