You might not realize it, but your alternator is one of the hardest working parts of your vehicle. Without the Mitsubishi alternator, the battery cannot recharge itself and if that happens, you won't be able to start your car. In the old days, an alternator only needed to put out 50-60 amps to power all the accessories in the vehicle. These days, alternators have a whole new lot of accessories to power. Now that we've got luxury items like heated seats, HID headlights, high-amp stereos, and power moon roofs alternators need to pack a harder punch. It's easy to see with all of these extras that a new alternator may be in your future. Many people look to the 100+ amp alternators to get the job done. Whenever one of the major alternator components goes bad (the rotor, stator,ignition coils, or diode packs), the whole alternator needs to be replaced.
