Hi there. I am having a issue and pretty sure its the ground. my head lights some times dim and on the dash the brights light comes on when this happens. The other reason i think its my ground is my stereo is also making a buzzing sound and that indicates a bad ground. My question is where is the ground located? I have checked under the hood and have determined its the earth ground but i dont know where to look since i am new to the rover.

 

Maybe AK will step in and help you, he has one and has some electrical knowledge around the head lights.
