Default Alternator Question



I was going to replace my alternator with an ACDELCO OEM 110 amps as part of my idler pulley, tensioner, etc. replacements when I noticed that I currently have a 230 amps alternator. I’ve only had the car 3 months and to the best of my knowledge it’s stock with the exception of a K&N CAI, magna flow catback exhaust, and an ATI harmonic balancer. That being said, it seems like everytime I start a new project I find something else that I wasn’t expecting.

Any idea why someone would put this on and if there are any issues I will induce by transitioning back to the stock alternator? Would the wiring be different than stock with this setup?

Unless you have a 50,000 watt sound system no need for a 230 amp alternator…110 is fine !!

You should read the alternator sticky. The C5 is picky about alternators.

Is the alternator not charging right or giving error codes? If not why do you want to replace it?
