EVERY time it kicks on, my voltage drops and dims all my lights
I'd make sure the belt is good'n tight. Maybe also take a quick look at the crank pulley. I wouldn't normally expect added drag from the compressor to slow down the alternator. Of course the crank pulley, (harmonic balancer), drives the whole works. It's unlikely it sheered it's key and is slipping on the crank.....I don't know why added drag would slow the alternator other than maybe that or just the rpm dropping.
new batt, alt? might want to look at alt field connector.
I just installed a new battery and alternator and it seems to help out but it isn't 100% cured, I have only noticed that it happens mostly when the vehicle is not all the way up to operating temp, but after it gets there it rarely if at all drops in voltage

well, I replaced the battery and alternator, and it seems to help, just not 100% cured, I have noticed that is usually only happens when the vehicle is not all the way up to operating temp, the belt is as tight as I can get it with the little bit of adjustment room I have as well.
Have you cleaned or replaced the battery terminals? The stock ones are notorious for corroding internally.
You could pull the alternator off and have it tested at an auto parts store or alternator rebuild shop.

Clean ALL the major grounds, clean the terminals going to the alternator and starter. If you are 100% sure your alternator is good, then the wiring would be the most likely culprit to voltage drop. Second most likely would be either a bad pulley causing the belt to slip, or the belt slipping for other reasons (water pump bearings, power steering pulley, alternator bearing and/or brushes)
Start with cleaning all the terminals, electrical connections, and ground points (use sandpaper, emery cloth, or steel wool) and see where it leaves you.
I have replaced the battery/terminals and the alternator, cleaned all connections as well, it helps but not 100% cured, I have noticed that it really only happens when the vehicle is not COMPLETELY up at operating temp.
having a dumb moment, but is that someone on here or is Xjwonders a website?
That would be me on here lol. Don't have a website yet but I'm currently building one at the moment. There's a thread in classifieds (buy/trade/sell) where I showcase my work.
