SL 600 - Battery Light... ON and OFF
 

I have a 1994 SL600 with an odd battery light issue.

Last night my battery light came on. I drove the car for a couple minutes and the battery light went off. After a few more miles the light returned.

Today, I started the car and the battery light was off. After driving for a few hours, the battery light returned. After pressing hard on the accelerator, the light would go off. When I stopped accelerating hard, the light would return. This is not a 100% correlation as there were times the light did not go off and I was at wide open throttle.

I just started the car about an hour ago and the light is off.

Any ideas? I made sure the battery and the wires connected to the positive terminal are connected tight. http://mbworld.org/forums/images/smilies/nixweiss.gif

MUCH APPRECIATED:(:(

Assuming the battery itself is either new or you know is fully charged, I'd suspect the voltage regulator; installs in the alternator, cheap fix around $40
