The battery warning light on dash board keep turn on then off when I step hard on the gas or merge into the highway... Please advise!
I did test the battery read: 12.6V (engine off). With the car is running (AC on, headlight on, radio on) the multi meter read 13.8V - 13.9V Seem like the alternator is also OK
BTW: I did an oil change and replace all new OEM spark plugs about 3 weeks ago. Would this have any thing to do with this issue?
