Running 1 alt VS 2 ...?


Recommended Posts

From what I read a dual alternator setup is best route but I'm a beginner(newbie). I am running about 8k and don't want any problems my factory electrical system. So that's why I'm keeping it separate. Good luck!!

P.S. hit up dc power on that bracket. Their customer service is great!

Dual alts, and separate charging systems is the way to go with 07' and newer GM vehicles IMO. Factory hot charges at 13.8 on mine but second alt hot charges 14.8-14.9

Do your second alternator have a 4 pin plug

most people are missing what is actually going on here....Your stock alt is regulated by the trucks computer. The computer tells it when to turn on and off and how much amperage to put out. so what ever alt goes in the stock location will use a 2 pin regulator plug and be controlled by the computer no matter if its a stock alt or a 370. This is on all 05 and newer GM vehicles. Doing a dual bracket will bypass the pcm control on the alt in the dual position and let it charge at maximum potential and voltage (14.9 set point on GM OEM regulators) so yes if you want the most out of you $800 alt buy a dual bracket.

Edit: yes the second alt will always have a 4 pin plug

NP, and some have 4 pin main alt.

Anyways, Kevosinn pretty much summed up what I was trying to say but he explained it 4x better, lol. Thanks Kev
