My lights flicker and dim when on the high way. The lights I am talking about are both the dash lights and the headlights.




Check battery posts and clamps (corrosion or loose). Then check wires from positive to alternator and negative to ground (no chafed or broken wires).

Check battery voltage 12 -12.5 engine off. 14 -14.5 engine running (you may want to revv high to simulate highway driving).

Check Fuse no. 10 (for ignition switch) in fuse box next to battery to see if it is loose or corroded.

These are similar suggestions to a previous post (except that post did not mention headlights dimming). Good luck.
