Ok I did a search first but, I didn't find the info I needed.
I have noticed now that it is getting darker out sooner I am driving with my lights on coming home from work.
When I stop at red lights in traffic with my wipers, headlamps, radio, defroster on. The dash and head lamps seem to dim.
I know this is common on old cars as the alternator does not put out enough amperage at idle.
What is causing this? Is it just the way it is or do I have a problem?
Thanks
