LOL true enough. Sorry for the delayed reply, as you've put some solid info together here. I think I ran out of motivation on my own effort (moved away from wiring to trying to get the motor in) which was what was pushing me to ask more questions. I think we're fairly close with what we have though. I'm going to put some more thought into this and likely ask some more questions, including a possible deviation from your above example setup for cars without rear batteries.

Re: Power Distribution

The Wiring can basically stay the same with a Battery in the Engine-Compartment.
Less or No Fire-Wall Pass Through connections would be needed.

Making a Diagram with the Battery installed in the rear of the Vehicle, just leaves more room to show the layout of the Wires.
But the same layout basically is still used with the battery under the Hood.

I figured as much. Only thing that would even be worth considering is downsizing the wire gauge as they're a good bit shorter and may not require being quite so big. However, there's no harm in it so probably best to leave it alone.

Re: Power Distribution

The Wire size can be down-sized.


I use heavy Gauge Wire to be safe, rather than sorry...
My Personal 3rd-Gen uses so many Electric Components, that I run a 250A Alternator... and need the larger Wire.
I know that many modern Builds also use multiple Electric Fuel-Pumps, Radiator Fans, Cooler Fans, Electric Water Pumps, Distributorless Ignition, Intercooler Water Pumps or Cool-Down Tank Pumps...
as well as Lighting, Exhaust cut-outs, Nitrous Bottle Heaters, and much more!

So there is often the need for the larger Wire... I just make sure my Builds can handle the Amperage demands.

Re: Power Distribution

I think this thread is ready for the sticky. Folks will surely ask more questions, and I'll probably add some pictures or questions myself as my build progresses. As time goes on, I'll flesh out the couple posts at the beginning with anything pertinent.

Thanks so much @vorteciroc and @QwkTrip .

Re: Power Distribution

We got lucky as heck with a guy like vorteciroc at the site. It's taken me a while to recognize he's not just smart, he's downright an expert with serious credentials on about anything he speaks to. People should listen when he talks.

LOL!

Come on, I thought everyone with multiple Masters Degrees, that went to work as an Engineer for GM...
and then later opened their own GM Specialty Power-Train Systems (Engine, Trans. T-Case, Diffs, PCM, Pow.-Dist.) Shop/ Business...
Were all a bunch of idiots!


All joking aside... There are MANY very intelligent Members here that contribute to the Forum.
So I do not feel that I deserve an more praise than anyone else that contributes.

College Degrees, complex Jobs, and Business success, do not add up to intelligence.
There are also many different forms of intelligence, that can be expressed in many different ways.

So I would like to praise all of you, that are on the Forum.
Thank you for contributing in your own ways, and for sharing the Knowledge/ Intelligence that you posses with all of the Forum.

Re: Power Distribution

I am still regularly being asked about Clean VS Dirty Power...
and I probably will for the rest of my days... Eesh!

I do not know how much more simply, I can put this.

What you should basically know is:
-Electronics should be Powered and Grounded directly at the Battery (Not a Chassis-Ground, Not a Power distribution Stud).
-Keep Electronics (and the corresponding Wiring) away from High Amperage Devices (and Wiring)...
(Starter-Motor, Alternator, Electric-Fans, Other Electric Motors and Pumps) all need to be separated away from Electronics.

Our Original Third-Gen Wiring/ Power Distribution is arranged so that most everything will receive Power off of the Starter-Motor Stud.
Even in the 1980s with very basic PCMs/ Control Modules...
The Power to the PCM is from the Battery (well almost... a Connector that is from the Battery via Fusible-Link) ...More importantly, NOT the Starter-Motor!

That is about as simple as I can make it.
