2001 Honda Prelude mileage: 108,000. Battery light will come on sometimes when the car is started, sometimes not for a while down the road, sometimes not at all. In addition, it sometimes flickers rapidly (not blinking, looks like a fluorescent bulb about to go out), then goes off for a while, and comes back on. I think this may be the voltage regulator. However, I do not know if the regulator is external, computer controlled, or integrated with the alternator. All connections to alternator/battery/fuse box/ignition coil/distributor checked, battery replaced a few days ago. I am not sure if the alternator is failing, as I drove the car for over 2 hrs with the light going on and off (mostly on). Btw, this all started after driving through an extremely rough section of road that was being repaired. Any advice would be greatly appreciated!

From what you tell us, it sounds like you may be having trouble with your charging system. Have your battery load tested and check the alternator output for voltage and amperage. You may have a diode in the alternator starting to leak.
