It could also be a bad ground somewhere.. I just replaced my alternator maybe 10k ago and my lights were still dimming at idle when the fan was on. I recently relocated my battery to the trunk and have 2 gauge for the battery ground, upgraded the 8 gauge tranny ground to 6 gauge, and have 8 gauge for the valve cover ground. No more lights dimming for me now. Although I still think my rebuilt alternator isn't at it's full potential.
