Q: If it's my alternator how long would that take to replace?

asked by on

My battery light came on. I had the battery checked and they told me that it wasn't the battery, probably the alternator but they couldn't check for that (It was a Valvoline place). The car started fine when I got out of work and the light came on. Hoping my car will start in the morning.

My car has 95000 miles.
My car has an automatic transmission.

The battery light can come on for a few different reasons in addition to a weak battery. I would suggest having the alternator tested. If this checks out fine and the is still on, also check the voltage regulator as this can also cause a problem with charging. In terms of the time it takes to replace, this will vary depending on the skill level of the mechanic and the tools used. A certified technician from YourMechanic can diagnose the battery light properly and replace the alternator if necessary.
