Alternator Rebuilding in Detroit
If your battery light is on or your charging system is dying, you don't need a whole new alternator from the dealer. We rebuild it right, and most are done the same day.
Signs your alternator is failing
- Battery or charging warning light on the dash
- Dim, bright, or flickering headlights
- Battery keeps dying even after a jump or replacement
- Whining, growling, or grinding from the front of the engine
- Electrical accessories (radio, windows, dash) acting up
- Burning-rubber or hot-electrical smell
What an alternator rebuild includes
- Free bench test to confirm the alternator is the problem
- New bearings for smooth, quiet operation
- New brushes and voltage regulator as needed
- Rebuilt or replaced rectifier / diode pack
- Cleaned and inspected housing, rotor, and stator
- Full load test on the finished unit before it leaves
Rebuilt to charge, and proven on the bench
An alternator keeps your battery charged and your electrical system running while the engine is on. When it wears out, the fix is rarely the whole unit, it's usually bearings, brushes, a regulator, or a rectifier. We open it up, replace what's worn with quality parts, and put it back together to spec.
The difference at Manfield is that nothing leaves without a load test. We run the rebuilt alternator on our test bench under load to confirm it charges correctly across the RPM range, the same machines you'll see in the shop. That's how you avoid installing a unit that fails again next week.
Bring in your alternator, or the whole vehicle, and we'll test it free. Have your year, make, model, and engine size ready when you call for the fastest quote.
