1999 Toyota Camry
I don’t have much knowledge about cars but this is what I understand. Whenever the engine is on, the alternator will always be generating electricity to power all components while charging the battery, because it is connected to the engine via serpentine belt. Does this mean even if you have a low battery and power hungry accessories, it’ll still generate the same amount of energy as if you don’t have many accessories on, and a full battery? Or does the alternator somehow adjust itself for more power output if this happens? I am wondering this because a few times I’ve heard if you have more power hungry lights and accessories you get worse gas mileage, but the engine will rotate your alternator the same amount no matter what just depending on how you drive from what I’ve seen. Can anyone debunk or prove this?
