OEM Auto Generators

Power Your Electrical System with Reliable Generators

The Bob Howard PDC parts team has all the parts you need to keep your vehicle running great. Generators produce electrical power to charge batteries and run electrical systems in older vehicles. These belt-driven components convert mechanical energy from the engine into electrical current through electromagnetic induction. Classic vehicles and some older trucks like certain Ford F-Series and Chevrolet C/K models use generators rather than modern alternators to maintain battery charge and power electrical accessories.

How Generators Create Electricity

Your generator connects to the engine via a belt that spins an armature inside electromagnetic field coils. This rotation generates direct current that flows to the battery and electrical system. A voltage regulator controls output to prevent overcharging. Brushes transfer electricity from the spinning armature to external circuits. The system maintains battery charge while powering lights, ignition, and accessories during engine operation.

Why Generators Fail Over Time

Brushes wear down from constant contact with the commutator, eventually losing electrical connection. Bearings fail from continuous spinning and lack of lubrication. Armature windings short circuit from heat and age. The commutator surface becomes pitted or worn, reducing efficiency. Generic aftermarket generators often use inferior brushes and bearings that wear faster than genuine OEM components. These cheap alternatives cannot maintain consistent voltage output, potentially damaging batteries and electrical components while failing to provide adequate power for modern electrical loads, affecting your starters and entire electrical system.

Replace Worn Generators Promptly

Install a new generator if your battery constantly runs down or warning lights illuminate. Dimming headlights and slow cranking indicate insufficient charging. Unusual noises from the generator suggest bearing failure. Most generators last between 50,000 and 100,000 miles in vintage applications, though rebuilding is sometimes possible with quality parts.
