Mobile alternator replacement

A battery light that comes on while you're driving usually means the alternator has stopped charging. From that moment the car is running on whatever is left in the battery.

Running on borrowed time

Once the alternator quits, the engine keeps going on battery power alone until the battery is empty. How long that lasts depends on what's switched on — headlights, fan and radio all shorten it.

If the light comes on while driving, turn off what you don't need and get somewhere safe to stop. Then call.

We confirm it before condemning it

We measure output at idle and under load, check the drive belt and tensioner, and check the battery itself. A slipping belt can mimic a failed alternator and costs a fraction as much.

You'll know which one it is before any part is ordered.

Why it's a starting price

From $155 labor on most vehicles. Some alternators sit right on top of the engine and come out in minutes; others mean removing a wheel liner or other parts to reach them.

We confirm the figure for your vehicle before starting. Parts supplied by us carry a warranty.

Questions

Alternators, answered

How do I know it's the alternator and not the battery?

A battery light while driving, headlights that dim and brighten with engine speed, or a car that dies again shortly after a jump start all point at the alternator. We test to confirm.

Can you replace it on the roadside?

Usually, as long as the spot is safe to work in. A parking lot or driveway is fine; a narrow shoulder in live traffic is not.

Why isn't the price fixed?

Access varies a lot between engines. We confirm the exact figure for your vehicle before starting.
