Before you scream alternator......This one is 10 monthes old and I've had it checked 4 times at different places with everyone saying it's working perfectly.

What happens is this: Most times (not ALL times) when Im driving my truck at night the all of my lights get dim/bright sporadically---even at WOT. My truck never acts like its going to die or anything, the lights just flicker.

I have a 2 gauge ground cable going from my battery to the intake manifold and this has worked perfectly for the last 3yrs. I tried cleaning the contacts points of the cable and even reconnected the factory ground to my ground. <img src="/forums/images/graemlins/angry.gif" alt="" />

Anybody want to take a shot at this one?

Later this week when I get a chance I'm going to add several more grounds around the engine bay (like those aftermarket grounding kits) and see if it was just interference or something <img src="/forums/images/graemlins/confused.gif" alt="" />
