  1. 3 alt wiring help

    in Electrical-battery- Alternators- Wiring

    Posted

    I wouldn't wire the two alts to the front battery, I would go straight to the rear bank positive and negative off the alt case. Do just one run daisy chained off each alt + and connect all three together then go to front battery just for ac alt noise filter. Going direct to the bank from the alts is the way to do it.

    That was my thinking from the beginning , as far as the front battery run daisy chain all three alts together and run 1 run to the battery? Or just run 3 runs (1 from each alt ) to the front?

    And do i still parallel all 4 batteries together in the rear or does that matter since they will be tied in at the alts any way?

    Thanks ami

    In your original post it says you have 3 alts? Did you car die? if not wire them up and make a vid I wanna see where you put the third alt I removed my ac and use the pully from it for my second I still cant see where you would put a third.

    I have the ac ps bracket fabbed up to hold 2 alts one on top of each other... Just like stock locations of ac and ps and stock mounting to block...I'll take pics when I get home

    They have not been installed yet, but was my thinking to NOT TO tie the 2 alts into the factory harness and leave the 3rd alt in stock location with stock plug controlling the car and front battery like normal. And have the 2 alts run the rear bank batteries eliminating those from the ELD completely

    If I was running a 16v system I'd have to isolate it then correct?

    Will this work?

    I will say something this is a civic hatch? so an eg? I dont think its going to be possible to run 3 alternators in a 1.6 l engine. even with hondas cool eld, I still think you will kill the engine once a load is place on the alts...

    It is an eg,

    If that is so, what's my options? With a draw of around 800a at full tilt?

    Really need some help figuring this out ;(

    Ok I need some help, I've spent the last 48 hrs readin all the dual/tri/quad, multiple run posts. And found many many conflicting options. So here's my set up and my thinking, so please feel free to comment cause daytona is like 6 weeks away.

    So ......

    On to the setup and thinking,

    3 180 alts, 2 on a dual custom mount and 1 in stock location

    The one in stock location charging the car battery and running all car accessories with dual 0 runs from alt and big 3 done

    The other 2 alts to the rear batteries(4) with dual 0g runs from each alt (4 0g runs total, 1 0g to each rear battery)

    Now heres my dilemma , GROUNDING!

    Now keep in mind it's in a civic hatch (unibody)

    My options I'm torn between are

    4 0g grounds from alt case(2 off each case) to a solid point up front AND 4 0g (1off each battery) to soild point in rear

    Or

    4 runs from alt cases straight to battery negatives ?

    And does the other front alt need to be tied in in any way? Or can I leave it the way Im thinking with the separation 2 alts for battery bank and 1alt for the car and accessories purposes?

    Thanks for any help in advance! Running outta time and need help to make it to daytona!

    Oh yeah,
