Utilizing the handheld starting and charging system tools commonly found at Napa, O'Reilly, and AutoZone are reminiscent of having the check engine light come on, scanning the vehicle for codes and obtaining a printout of fifty to one hundred things it could be. At best, they'll put you in the ballpark or near vicinity of the problem. At worst, you'll be chasing unconfirmed sightings of Big Foot wasting both time and money. Had both an alternator and battery fail on separate vehicles shortly after being told everything checked out fine by the counter "technician". They are merely good resources to help isolate and pinpoint the problem, but shouldn't be solely relied upon. On a different note, was told that bench testing a starter, battery or alternator is more accurate than testing one on a vehicle, but either the person didn't know or couldn't explain why. Believe their handheld systems mainly check current flow i.e if the alternator is producing the right voltage, so forth and so on. Try checking the plug-in connector on the back of the alternator for frayed, damaged, or loose wiring. Check the stud bolt (alternator ground) as well for a good connection by making sure the nut is properly seated against the wire. Prior to starting the car, check the tightness of the belt by pulling upwards as it should have plenty of resistance. Visually check the rotation and movement of the alternator pulley while the vehicle is running. Does it spin freely? Visually check for belt looseness as it travels along the various pulleys for bulges or inconsistencies. The serpentine belt is designed to last well beyond 100,000 and yours should much of its useful life remaining. The charging system light indicates it is not being charging properly and the alternator message on the driver information center indicates it is not providing ample power to charge the system. The battery supplies power to the starter motor and turns the pinion gear which in turn engages the flywheel and starts the engine. If you must drive the G8, remember to turn off an unnecessary accessories such as the air conditioner and radio to reduce the power draw and prolong the longevity of the discharging battery. The charge on the battery is going to determine how long and far you will be able to drive the car in its current state. Probably way much more than you were asking, but hopefully this helps. Best of luck
