So i was bored last night and went for a cruise for about 1/2 hour, stopped to get a coffee (thats right, at night), got back in the car and started 'er up and the charge light stayed on. I started driving it a bit and it would flicker on and off depending on the rpm's, and after a while it would stay on below 2500rpm's. Also, the voltage gauge would sit lower than usual at idle, while my lights would dim quite a bit.
So first thing in the morning I start her up no problem, and the charge light does not come on. I take it to the local parts place and had my alternator and battery checked, both on the car and on a bench tester, and both showed no signs of any problems. Checked all the underhood connections and they looked clean, no damaged wires that I could see. The battery cable ends are in good shape as well. Could all this just be due to the underdrive pulleys not allowing a decent charge at idle when the system is under load (headlights, radio, fan, etc)? I don't see the voltmeter flicker at all during the day like it does at night.
Can anyone else think of anything else I can check or should I just accept it as it is? I'm going on a long trip in a month and I don't want to be stuck on the side of a highway with a dead battery. Sorry for making this so long....
BTW I have the stock pulley on the alternator and the idle is at around 700rpm
