So I've been battling an ongoing electrical problem in my car for some time now. My battery has been dying/draining too much. I have been able to deduece that I have a 90mA draw coming from fuse 21, I'm working on fixing that.
Now, 90mA is indeed a drain, but it doesn't seem like a lot. I recently charged my battery to %100 and slowly over time, I noticed it dying (cranking speed became slower, etc). I drive the car almost every day.
When my car is idling, I measured the voltage across the battery to be around 12.4 V. Keep in mind that this is on a dead battery (had to jump start it to start the car). I've heard that 14ish is the ideal voltage to read across a battery while idling, is this true? Is my alternator dead/dying?
COLES NOTES: Is 12.4V too low of a reading to be getting across the battery at idle? (this battery is quite dead though, not sure if that makes a difference)
