Dim Headlights on a 02 Santa Fe
 

Ok..Let me know if anyone has a clue on this one. My daughter has been
complaining about her headlights not being quite bright enough, so I marched
out with my trusty voltmeter and checked it out. The negative (pink with
white line) wire to the bulbs is sitting at 1.5 volts above 12v negative
battery ground. I'm showing that with the engine running and 14.1 charging
volts, the headlamps are getting an effective 12.5 volts.

Any ideas here? Has anyone seen this before? Any help would be much
appreciated.
