Voltage drop

It a quick question. I have never noticed it before but when I turn my headlights on my voltage will drop about 1 volt. I have never noticed it before. What could this be? My voltage seems a little high. On my auto meter gauge I can see that it is tight at 1 volt only when I turn the headlights on. I can turn the interior and the parking lights on with no change. It's when I turn on my headlights that I get the drop. Any help would be great.

I'm Not sure exactly but I would think that your headlights pull a lot more juice than you interior or parking lights.

I just wouldnt think that there should be any voltage drop. I know my voltage ia a little high. It is around 14-15 volts. When I turn the headlights on it drops about 1 volt. I have my auto meter gauge hooked to the fuse that controls the radio so I am pretty sure it is accurate. Is it normal to have a voltage drop like that when u turn the headlights on?

Re: Voltage drop

Yes, it is normal to have some voltage drop when you turn on a high amperage accessory.
