14Fusion Posted March 24, 2015 Report Share Posted March 24, 2015 I have a question for the people with the dual alternator setups. Do I need ground the second alternator case to the battery? My audio is separate from the factory charging system. Where are you planning to ground it? Depending on the way you are mounting it it would be grounded through the other alt.

But I heard it's was not necessary because the bracket is bolted to the engine block grounding the alternator? 151.0 Sealed http://www.stevemeadedesigns.com/board/topic/196628-2007-escalade-build-my-first-install/ Link to comment Share on other sites More sharing options...

Karkov Posted March 24, 2015 Report Share Posted March 24, 2015 If you have two separate charging systems then do the big 3 like normal on the second alt. The ONLY 2 things the alts will have in common is the belt (and of course the frame/body of the vehicle) Big 3 upgrade as normal: Alternator ground to chassis/frame Battery ground to chassis/frame (I like to use a common ground location for the two of these) Alternator positive to battery positive. You'll hear mixed opinions on this, but personally I like to fuse this one too Another thing, the facotry charge wire should always come last on the alt stud. 1/0 wire runs should go on first. Hold, I will go take a pic. of mine, because separate charging systems... 2007 Chevy Tahoe (SOLD) 12 ~ FI Audio X series 10" w/BP option 2 ~ DC Audio 5.0K @0.67 3 ~ DC Audio 5.0K @1.0 2 ~ PPI 3 way sets (not installed yet) 1 ~ RF T400-4, 1 ~ RF T600-2, 1 ~ RF T600-4 4 ~ CT Sounds 5.25" Strato comps (rear fill only) 1 ~ XS Power D4800 1 ~ XS Power D3400 8 ~ XS Power XP3000 160 stock alt, Mechman 370 Elite, 185 DC Power 320+ Sq.

Karkov Posted March 24, 2015 Report Share Posted March 24, 2015 Oh, sorry, the bolt that holds alternator in is where the one ground goes to. Even if you only had stock alt the grounding point would be the same. As you said, it's mounted to engine/frame anyway. Also, i get ZERO alt whine, both systems charge like a boss. 2007 Chevy Tahoe (SOLD) 12 ~ FI Audio X series 10" w/BP option 2 ~ DC Audio 5.0K @0.67 3 ~ DC Audio 5.0K @1.0 2 ~ PPI 3 way sets (not installed yet) 1 ~ RF T400-4, 1 ~ RF T600-2, 1 ~ RF T600-4 4 ~ CT Sounds 5.25" Strato comps (rear fill only) 1 ~ XS Power D4800 1 ~ XS Power D3400 8 ~ XS Power XP3000 160 stock alt, Mechman 370 Elite, 185 DC Power 320+ Sq.

Rodlow1 Posted March 24, 2015 Author Report Share Posted March 24, 2015 Do your alternator have a ground stud? Or what did you do?

You are the freaking man!! THANKS!! Did you scrap the alternator housing or can I just add the wire? 151.0 Sealed http://www.stevemeadedesigns.com/board/topic/196628-2007-escalade-build-my-first-install/ Link to comment Share on other sites More sharing options...
Karkov Posted March 24, 2015 Report Share Posted March 24, 2015 If you look in my first pic. the alternator on the left (stock) has two mounting bolts, the bolt on the Right actually has an engraving saying grounding location or something like that. Because of that my alt(s) do not have their own grounding stud per say. I don't think it would matter to scrape it but it also wouldn't hurt, since you can easily do it now I would scrape it just for piece of mind. 2007 Chevy Tahoe (SOLD) 12 ~ FI Audio X series 10" w/BP option 2 ~ DC Audio 5.0K @0.67 3 ~ DC Audio 5.0K @1.0 2 ~ PPI 3 way sets (not installed yet) 1 ~ RF T400-4, 1 ~ RF T600-2, 1 ~ RF T600-4 4 ~ CT Sounds 5.25" Strato comps (rear fill only) 1 ~ XS Power D4800 1 ~ XS Power D3400 8 ~ XS Power XP3000 160 stock alt, Mechman 370 Elite, 185 DC Power 320+ Sq.
