Pontiac Fiero Alternator

The Pontiac Fiero alternator is specifically an electronically regulated charges the Fiero's battery and powers the vehicle electrical system while the car is in operation. Usually it is situated ahead of the engine and it transfers mechanical energy from the engine to electrical energy which is supplied to components such as battery and others. It employs a rotating magnet field and a fixed armature to produce the alternating current (AC) necessary to re-charge the battery and the electrical system of the vehicle. the voltage output of the alternator will be controlled in such a way so as to check deep under charging or over charging. However, if the electrical load in the vehicle rises, then there might be a need to install a high output alternator in order to cater for the additional load exerted by the additional parts for the charging system. These are high powered alternators developed to generate more amperes to suit cars modified to have more electrical conveniences.
