3 alt wiring help

[steven]

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?

Your eld is a good thing it forces your rpms to rise automatically when your voltage drops it would be better if you just run all your alts together and stick with a normal charge rate 16 volts would be harder to maintain. Dual alts with some good batteries will good for your electrical demands

Thanks Steven and mrskippyj I appreciate all your input, I'll post pics and results.

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

Parallel the batteries in the rear that makes them a bank they act like one big battery. You need all the alt connected to help filter out ac diode noise by connecting them to the front battery that act like s buffer and helps filter out alt whine. Do like you were thinking one alt running the vehicle and out two running the bank, if you wire them all to the front battery first and then to the rear that is just one more stop the current has to make on it's way toward the rear, plus demand won't be at the battery so why connect all the alts to that point? It isn't necessary you just need one connection there not multiple. Well I guess two for proper buffer.
