about to pull into driveway today....7 starts making weird humming noise and battery light comes on along with the oil pressure light and overheat light even though those gauges dont get pegged. Is it as simple as it seems...battery or alternator, or could this be something much worse. Pulled the car in the driveway and shut down and restarted it and it did restart with that noise coming back along with the lights and dimming. Opened hood and checked for odd smells or leaks with nothing going on. Thanks for any help!
