Thread: Question: Arise psu: ground, neg, and pos.....?

I'm very confused by what you are saying, but I think I get most of it.

DO NOT connect the Arise supply outputs to a distribution block. Not only is there no reason to, but you will shot the supply if you connect the negative output to ground. Connect the outputs of the Arise supply directly to the computer only.

FYI:

In electrical circuits, three different terms can be used for voltage:

Positive
Refers to a voltage above ground.
Negative
Refers to a voltage below ground. For example, the -5V output from the Arise supply is 5 volts below ground. So you can see why you can't connect it to ground.
Ground
The point of 0 volts, between positive and negative.

I guess my brain was a little fuzzy the other night when I asked this. Working overnights especially doesn't help. Wanting to get things done instead of having the patience to wait until sleep is achieved can be detrimental, which is why I chose to sleep on it. Now, today, I'm ready to complete the install and reroute the grounding for the electronics in the truck.

Aaron, you misunderstood my question. I was referring to the Arise's INPUTS, not outs.

I've decided to remove the ground run from the battery to the neg distro block. In its place I'll run one 6AWG line from the distro block to a seat-mount bolt. Then, the Arise's neg will go to that neg distro block. The Arise's ground doesn't need to be used since it would just be going to the same ground reference as the negative, the seat mount bolt. This would also be a safer install since if ever the battery/chassis ground got loose or faulty, the ground path for the battery would NOT be down the wire to the distro block, into my radios, Arise, PC, etc.... You ever see equipment welded because of a bad ground? I have. It's not pretty when you figure up the cost of replacements.
