Got all my electrical supplied picked out. XS d3100 on the way, waiting to hear back from DC on the alternator. 4/0 welding wire. Now, how to put all of this shit together. I had another user help me answer this, but I thought I would widen the knowledge base. So I am looking at wiring, and just curious about different wiring styles. This is an idea I recieved from a guy on here I assume knows what he is talking about.
"I still use the factory grounds. I simply give the auxiliary system a better means of conveying the energy.
In a perfect world, that system would be in addition to the factory system
2nd alternator and batteries just for the stereo.
In my truck I only intend to have one alternator. so the original system will be connected to it also.
the engine block needs it's ground for the starter, EFI system, sensors and other things which run off of it. So the engine block to body connection still needs to be there.
The battery ground to the body needs to be there also for the computer and dash and everything to work.
I simply add the upgrade wiring to do the job it's intended for. factory wiring can remain intact including the factory alternator power wires.
my drawing only depicts the 1/0 circuit."
This makes perfect sense, but does the option to ground my aux wire from alternator mount to battery (-) have advantages? As opposed to just using the "Big 3" style upgrade?
Now this is the idea that I had.
I have questions about these. 2 major differences I see is that the first has no ground directly from the battery. Are there pros/cons to this? Does it just ground directly from the alternator's connection to the engine block instead of taking a trip from the battery (-), to the block, to the alternator? So instead of making a ground AND a connection to the engine block, you just combine then directly and run the wire directly to the alternator engine block connection? What do you guys think?
