I Bought my 02 WRX in August and been fixing problems since I got it, but i recently ran into an issue and I've never experienced this before. The past few days, Ive started my car and the Brake light + the battery light come on and my voltage gauge reads 10v and all my accessories are dim. Eventually after driving for about 5 minutes, the voltage will come back and it all goes away. Well now today it stayed on all the way home and never went away, then i pulled in my driveway and revved it up to about 5500 to 6000 and most of the voltage came back to 12v even though it usually sits around 13.5 to 14 and the lights went off and everything seems fine but then i popped the hood and right at the connector on top of the alternator was glowing red. Does my Alternator just going bad and need to be replaced? or is it something worse? Please Help, I dont want to replace an alternator and find out im still having the same issue.
