Charging issue

Recently I noticed with headlights and fog lights on when I push window buttons up hold the button in even after windows up my lights dim and the fan blower dim. I have an Optima red top battery only about six months old not even.

I wouldn't worry about it. Even with a new alternator and battery my truck did this, and still does it to this day.

 

If it really bugs you, do the big three.

 

Just making sure it not Gona mess something up nore

I really need to take the time to do that someday.

 

It shouldn't mess anything up. On my truck, I can hear the heater slow down just by flipping my high beams on Lol.

 

Nothing abnormal you should be fine
