Well, I read through the rest of the answers, and didn't see one that strikes me as obvious: you may have little or no deflection in the alternator belt, but slack in the belt driving the A/C pump pulley will do the same thing. Your alternator belt is driven off the second half of the twin-groove idler pulley there (OK, it's only an idler when the A/C isn't being used!). I recently encountered this particular problem myself, after a bolt broke and "adjusted" [ahem...] my A/C drive belt for me. I'd checked the alternator belt like three times, and pulled out the regulator to check brushes, even pulled the belt off and tried wiggling the pulley end to see of the other end's bearings were going bad (that's another place to watch for problems, when your symptom is a glowing battery light at higher rpm's, BTW). Finally dawned on me that I wasn't tracking mechanical energy transfer all the way back to the crankshaft. HTH!

My battery light has been coming on lately. When I first start the car up the battery light is at its brightest. The longer I drive and the higher the rpms, say above 5k, the light gets dimmer and eventually goes off. I thought it was just the belt slipping but there doesn't seem to be a lot of deflection in the alt belt. The brushes on the volt regulator look fine also. Does the light come on when the battery isn't seeing a specific voltage #? Anyone have some suggestions on the cause, I don't have my Bentley handy.
