Hey all,
I'm chasing down a minor electrical problem in my car. Seems like the right brake light circuit always tests about 11.6 volts, which is about
0.2 volts lower than the left brake light circuit that tests about 11.8 volts. Both lights work but everytime I press the brakes, signal a right turn or turn the hazards on, the red LED on my graphic display lights up. Obviously not a critical issue, just gets me thinking... and tinkering.Using some test leads I crossed the L/R brake light signals to the graphic display and make the LED light up using the left turn signal, but that exercise didn't really tell me too much. Testing resistance is tough because I only get a reading with my foot off the brake pedal, and it seems to be fluctuating, so hard to peg either side.
I have schematics and just wondering if there are any probable causes, like resistance, shorts to ground, bulbs, etc. Other than a light being out, I'm not sure what the graphic display is designed to sense. I have confirmed all bulbs are operational.
Thanks, Matt
