What is the definitive test for a bad alternator?
Quick history:
- Tried to start the car after it sat for over a month. Battery was flat. hooked up to CTek charger overnight. Car started fine, drove for a day no issues.
- Tried starting it again after a week, battery flat again. Replaced with an AGM from Oreilly's. All seemed fine for a couple days.
- About a week later, flat battery again. Jump started and went to Oreilly's. They tested battery said it did need charging, but the test suggested alternator may be an issue. Battery had a date sticker of 10/17...so not an issue of sitting around too long.
The only reason I am questioning a bad alternator is that there is no sort of battery warning light, dimming lights or other bad alternator signs (besides battery not charging). Am I just trying to convince myself the battery (easy fix) is the problem...and not the alternator?
