• Use Your Eyes: Usually when our customers complain of an alternator issue it just takes a quick look to find a belt missing, hanging off the engine block or so loose it’s flapping around the engine compartment. A quick visual check of the belt for cracking, excessive wear marks and other visual related problems can give you some idea of what may be the problem. Also, the drive belt must have the proper tension to run the alternator correctly; too much tension is just as bad as not enough. A quick check of the belt tension is usually enough to determine if a problem exists.
• Use Your Ears: We also see our customers complain about hearing a “growling” or “whining” noise before an alternator gives out. The alternator is driven by either an accessory belt or a serpentine belt in conjunction with the crankshaft pulley. The alternator pulley typically spins about two or three times faster than the crankshaft pulley to produce the power necessary at lower engine speeds, such as at idle. If the pulley is not in correct alignment with the belt, if it’s canted on the shaft or if the bearings and bushing are worn out, the growling or whining noise will let you know there’s a problem.
• Use Your Nose: The smell of burning rubber or hot alternator wires will often accompany alternator failure. A pulley that isn’t in alignment or not turning freely will cause more friction on the belt, which creates heat and then the smell of burning rubber. The hot alternator wire scent can be caused by an overheated alternator, so keep your nose in tune with your vehicle.
