Default Lights Dim Momentarily

2002 recently bought. Notice with night driving and engine idleing and headlights the headlights will dim for a moment when the rad fan comes on. This normal or is this the sign of something bigger. Battery cables are clean but not sure down at alternator.

Same thing used to happen with my 08 PT until getting around to replacing the puny stock battery cables with larger guage (#4awg copper) and using better terminals. Also removed the ridiculous sheet metal screw ground on the left inner fender and replaced it with a bolt and bonded all the ground points together with #10awg the dimming issue is barely noticeable if at all plus much better electrical performance including stronger starter cranking.

No it's not mormal. Agree with Carl. Have the battery and whole charging system checked out. Most decent auto stores will do it for free. Check and clean all the cables connected to the battery and check the grounding.
