battery light on, read this mystery

[falconetti]

pretty simple. battery light will come on througout the day. on, then off. if its on and i rev it up, it goes off. while its on radio is in low power mode. here are the findings. while running the volts are a steady 13.8, when the light comes on the volts have dropped to 13.5, just on the edge of 13.4 the low power mode affects radio, rev it up and it hits 14.2 volts and cures the problem temporarily volts necer drop below 13.4 even under load. unable to determine what else may affect it or cause the minor drop in volts. reving up rpm's are the only thing that i can use to change the volts...sooo any thoughts?

Might be time for a new battery. The LR3 has a lot of electronic gadgets that apparently put quite a drain on the battery. The same applies to many modern computerized cars. I read that 24V might become the norm for cars of the future.
