Battery and alternator replaced couple years ago. With light on, still reading 14.2 volts off alternator and battery.
Put volt meter on both battery and alt, reads 14.2 volts. When I put a load on system, voltage initially drops to about 13.7, but quickly recovers. I have not noticed any dimming of the headlights or dash lights at night while light is on, so I don't believe the issue to be the regulator.
Problem has been going on for about 3 weeks. Car is running fine, no issues with starting. Could issue be with the light itself, or something with the PCM?
