THrew a ses light so my buddy scanned it and it was throwing high voltage codes. THe fuse under my hood is also blowing (60A fuse) I do have 2 batteries in my car and the back battery has a 160A fuse on it which has never blown, I have never had a problem the past 2 years until now. I noticed the lights were also dimming at idle so I figured the voltage regulator was going out so I put in a new alternator and cleared the code, 2 days later the fuse blows again and it is throwing high voltage codes again. A guy here at work just tested both batteries and the alternator and everything is reading normal so we are kind of stumped.. Voltage appears normal on my volt meter but sometimes goes to about 15.4-15.5, slowly though, and if I turn on my system it drops to normal. any ideas?
