Ok, I still have my issue, and now I am starting to get more than slightly aggravated.
Headlights, and interior lights dim when the brake is pushed. Since Im doing a complete overhaul anyway I bought a brand new alternator, not a reman, new battery, new terminals, and even replaced my grounds. New bulbs, and checked all the light wiring. Also replaced all the fuses in the box. Had the alt and batt tested at ford after putting in the new stuff because sometimes there are issues, but everything checked out.
The multi meter is showing that everything is good, batt to alt, batt to block, batt to frame, alt to box, etc etc.
What else could I possibly be missing here?!
