My generator idiot light has been coming on at start-up lately. When I tap the gas the light will go off and will not come back on at all during a cruise. A few days ago, we tried to do something with my A/C, and then I was noticing this light at start-up problem. Eventually starting my car was sluggish, and then I got stuck somewhere. Since I hadn't died while driving, I didn't think it was an alternator problem. I got jumped and was good to go and charged my battery. We felt the alternator belt was a bit loose so we retightend it. I also felt a loose belt was maybe a cause because my cell phone charger was acting really crazy (going on and off) if I was not in a high RPM in any of my gears I drove it a few places during the last day and a half and have had no problems. Just a bit ago I went to go somewhere and the light came on at start-up again, and with the tap of the gas it went away. I just got a new voltimeter, so I'm wondering what I should check and what to look for. The alternator, by the way, is still externally regulated. Thanks.
