While your Mitsubishi is running, a little device inside the engine compartment is hard at work charging the battery back up, so that you may start the vehicle the next morning. This part is called the Mitsubishi alternator, and it does more than charge the battery. It also provides all the power for the lights, radio, and other electronic devices while the engine is running. The Mitsubishi alternator uses three separate circuits to produce alternating current electricity. The vehicle must have direct current electricity for all of its needs. Fortunately, the Mitsubishi alternator incorporates the needed components to turn the alternating current into direct current. Direct current operates at a constant voltage, traveling from the negative side to the positive side. Like your house, the Mitsubishi alternator produces alternating current, which travels from negative to positive, with voltage that climbs from nothing to the maximum, and back down to nothing. Then the current reverses to travel from positive to negative, in the same voltage range. When one of the three circuits in the Mitsubishi alternator fails, the vehicle may appear to keep operating normally, though the battery may not have a full charge. Soon the extra demand placed on the two other circuits will render the Mitsubishi alternator completely inoperable, at which time it will need to be replaced. Our online catalog has the perfect model for your vehicle, at a price that is much less than what the dealership would charge.
