How to tell if I need a new alternator or battery
The other day a alternator malfunction code popped up but then disappeared, I ignored it. So then the next day I drove it around no issues but then the code popped up again at night. Do I need a new alternator? And what are some ways to check if it’s my alternator or battery? Thank you to anyone that responds, your help is greatly appreciated.

Bearings last a very long time. If it's a Valeo, you can with some searching find a new regulator/brushes set for around $50. The brushes in particular wear out over 100K miles. Takes some searching, but look around alternator supply companies.
