Re: Electronics, how do they work?
The single relay is definitely a big problem if they draw 15A each. That's 45A continuous, not to mention the initial current draw may be 3 times that amount on turn-on depending on the compressor motor inductance.
The skinny wire you're talking about is most likely the ground for the relay coil. If there is only one wire going to each compressor, that must mean that the compressors are grounded directly to wherever they are mounted (through the metal case of the compressor, etc).
Seriously though, there is no reason to run 8 gauge for 3 compressors that draw 15A each, unless you're planning on blowing the horns for a long time.

Re: Electronics, how do they work?
I'm pretty much done with arguing this topic, but I will say in closing that a lot of people use wire that is waaaay too large based on the actual requirements. It doesn't hurt anything, but it is a pain in the ass to crimp a terminal on 8 gauge instead of a more proper sized wire that is still perfectly fine for the job.

I'll just take a picture of it tomorrow. There are two wires to each compressor, and the ground wires ground to the chassis.

Having and needing are two completely unrelated things.

edit: Crimping large stuff isn't a pain with the right tools, but smaller AWG is certainly easier to work with.

Agreed, and if you find a smaller gauge fused d-block (one 8AWG in to three or four 10-12AWG out) holler at me. I'm still looking for one like this as they tidy things up nicely. That was the primary rationale for using one run of larger AWG.

A razor blade, a vise and a punch and hammer. The tools you need to crimp big wire. That simple.

BTW I have 2 large fans to run that on the same switch and are run constant on. This aint no honda I got.
Guess what buddy, I ran a tiny wire going to a switch inside my car you know what happen? The wire got hot, and ended up melting. Plus the car would always overheat do to LACK OF CURRENT to the motors. So I did need it.

Re: Electronics, how do they work?
Wait, so you're running the fans off of a switch and not a relay? So you went from a tiny wire to 8 gauge wire, and you're still running the fans directly through a switch. I'm just trying to get my facts straight here before I completely discount your wiring advice.

Re: Electronics, how do they work?
Nope why the hell do I have to run a relay?
Its connected directly to the battery, I also have each fan running 8ga ea, then going to a switch. Theres also a fuse inline for it to.
Tiny wire was 10ga wire that shity radioshack sold that had more insulation than wire. It just didnt work. That's tiny wire to me.
Relays are low current switches for high current devices, Its not required to run one, as long as the switch is rated for the current........... correct.
I did have a relay, but couldnt find connectors for 8ga wire, to connect it. I also have an auto reset circut breaker.
Thanks for trying to flame me.
Carry on.
