[QUOTE="bbeljefe, post: 8252147, member: 655960"] Yes, it is very common. Any bad connection in the power circuit can cause dimming. If you put a broken link in a chain, it doesn't matter where that broken link is located... the entire chain is weakened. As for where to ground, you may be able to find another location but a lot of unibody cars are assembled with epoxies now instead of welding so one panel may not be electrically bonded with the next. You can use a volt meter to check the resistance in your ground wire but it will not show a weak connection. i.e., at low current your ground path may not be weak but once you start drawing higher current through it, resistance can increase. Your best bet is to install the system properly and run a dedicated ground. I understand that it isn't easy to do but you don't have to do it every day. Just do it right once and you'll be good.
