Rebuilding an Alternator: The Complete DIY Step-by-Step Guide
Rebuilding an Alternator vs. Buying a Remanufactured Alternator Quick Summary Most alternator problems are due to: 1) Failed diodes or rectifier 2) Failed voltage regulator 3) Worn brushes or slip rings 4) Worn bearings • These are easily replaceable items. However, before considering a rebuild, always diagnose the charging system before removing the alternator. A badly corroded battery cable, ground, belt, or connection can imitate alternator failure. • Inspect the rotor, stator, housing, and slip rings before spending money on rebuild parts. • Never hammer new bearings into place. Use … Read More
How an Alternator Works In Modern Charging Systems
How an Alternator Works in Today’s Computer-Controlled Vehicles Quick Summary Modern charging systems are far more sophisticated than older designs and now operate as part of a computer-controlled charging system. The key things to understand are simple but important. The alternator generates electricity using a rotating magnetic field inside a stationary stator winding. The electrical output is converted from AC to DC by a rectifier and then regulated by controlling current through the rotor’s field coil. Modern vehicles often use computer-controlled smart charging, in which the engine control module adjusts … Read More
