I know this has been written about many times...but I can't find the answer. The brightness of my dash does change when shining a LCD flash light on the photocell. SO I guess the photecell is good. The dash also gets brighter when I turn on the lights. There is NO change when I adjust the brightness lever. I read that this problem is often caused by a bad ground. Where do I look for the bad ground?

Also if not a bad ground, what else might the problem be, and what is the possible cure?

THANKS for any help of ideas!!!
