All of the indicator lights (from the battery icon to the ABS) on the dash turns on intermittently. It happened a while back (about 4 months ago) when I was stuck in traffic for 3 hrs, but when I revved the engine all the indicator lights would turn off.

The other day it turned on as I was on the freeway. I did a search on this forum and took out the regulator behind the alternator. The brushes were fine, but there were black debris on the diode (electronic part of the regulator). I cleaned it up and put it back in. All the indicator lights are now off, but it flickered on twice when I tested it earlier.

The engine runs fine whether or not the indicator lights are on. But the car does seems to lack electricity for the radio and lights when all the indicator lights are on.

I have a hunch my alternator may be bad, but why would all the indicator lights from the battery icon to the ABS turn on. I would think only the battery icon would light up if the alternator was bad.

What should I do?
