I have checked all connections and they seem to be good, the alternater and oxs lights turn on when the car is idling, then go off when the car is revved up. What is the next step to fix this, buy a new battery? or get the alternator tested. I read some past posts, but just want to be sure i do the right thing. FWIW the car only has 75k on it so i am not sure if the alt. would already go bad. The battery is some weird off brand that the PO had put in. Where do i go from here?
