Multiple Ground
Hello,
I am trying to troubleshoot me headlights and was surprised to find in the schematics for combination lamp connector several terminals connected to ground. In my case they were terminals 4, 8 and 10. From electrical point of view they should have the same potential (which is 0V), and look redundant, but from life experience I believe that if manufacturer took efforts to make extra parts there is a reason for that. Can somebody explain why I need separate ground for high beam, low bean and turn signals?
The schematics are here:
2004 - http://boredmder.com/FSMs/Nissan/Maxima/2004/LT.pdf
2007 - http://boredmder.com/FSMs/Nissan/Maxima/2007/LT.pdf
Thank you in advance,
