OldsBoomer Posted March 7, 2013 Report Share Posted March 7, 2013 Ive got 4 16v batts already but finding space for how I want things under the hood in becoming a PITA. I have a dual alt setup on my 98 Burban. I am putting 2 D3400's up front and the 16v batts in the back but with the external rectifer and regulator of one of my alts and the 6 runs for the battery bank its getting a bit of a cluster fu*k. I could throw a 16v batt up front i guess but then ill have a 12v in the back which i wanted to avoid plus it wont be as clean under the hood. Think its worth the gains in effiency with the 16v to stick with it or go back to all 12v and have more total amps for everything but less power for the sub stage?

Tarball Posted March 8, 2013 Report Share Posted March 8, 2013 if your rectifier for the 16v setup is in the rear, what do you need 6 runs for ?

OldsBoomer Posted March 8, 2013 Author Report Share Posted March 8, 2013 The rectifier is up front since it wouldn't be good to have it so far from the alt increasing resistance in line. I have to take the three phases to the rectifier. Suburban Coming Soon Link to comment Share on other sites More sharing options...
Tarball Posted March 8, 2013 Report Share Posted March 8, 2013 I may be wrong but it seems you would have a simpler time fighter resistance with AC than with DC. As long as you take safety precautions (maybe even conduit) to run your 3 phase wires to the rectifier you'll likely save a shit load on 1/0 not to mention reducing the heat of the rectifier by taking it our of the engine compartment; hell run an ac vent on it! Food for thought anyway.

Food for thought anyway. True I may talk to my lineman buddy about at resistance. Didn't think about the difference in current and the effect on resistance Suburban Coming Soon Link to comment Share on other sites More sharing options...
