UPDATE: After completing the install my alternator isn't charging the battery. Please see the post at the bottom of the page
So I have a '75 280z and recently I've noticed my headlights get brighter when I rev the car. (Both in neutral at stand still and in motion)
I also noticed that my dash lights and interior lights get brighter as well.
The headlights are also very dim whether or not the car is revving or not, revving only brightens them a little and overall they're still dim.
The A/C fan also gets louder and blows harder when revving.
So somehow all of these problems are connected to something and I'm at a loss on what to do next.
I've been reading a lot about this and my best guess is there's a problem with the grounds.
If so, where are the grounds located?
My problem isn't with the lights/fan getting brighter, but a possible problem with low voltage getting to these systems at idle (or in general)
What do you guys think could be the source of all this?
Sorry for the barrage of questions but I'm new to electrical gremlins and it's all especially confusing to me.
Thanks for any help
