Luminas = Delco 105 amp alts.

I kept the stock alt on my 98 Lumina. I had a Yellow Top in the trunk and the big 3 done. I didn't really have any light dimming once I got that extra battery in off 2kw.

was the big 3 hard to do with your lumina? and what were you running?

Nah not really i mean if you don't count the gay positioning of the battery (under the strut bar and windshield wiper fluid). Since the alternator sits on the top left of the engine its fairly easy to get to.

Everytime I did something to the battery in that car at the end of the day it looked like i banged a smurf... Blue windshield wiper fluid FTL!

I've had a buncha different sh*t in that car. It has gone to Lumina heaven with 150k miles on it (transmission was slippin didn't wanna replace) and has been replaced by an '01 impala.

how about if i uped my amp kit, just got a crapp 8gaueg one atm, think 0-4 gauge would be better for power wire? well i know its better but would it help or no

Even if you were going to upgrade your alt, you'd STILL want to do the big 3 to maximize that upgrade. Knowing this, it only makes sense to do the big 3 first and see if that's all you need. And if you do not know how old your batt is, chances are it needs replaced too.

Be smart, start with the basics and move on from there.
