melted cables
i dont know much about this electrical stuff but i definately did something wrong on this hook up... the cables on my amplifier/subwoofer set up started to melt around the nodes on my capacitor, anyone have any ideas why it might be doing that?

You have a ground and a power wire in any electrical circuit. If the ground is too long or is not touching a large piece of metal then, there is not enough or no ground. A circuit with a poor ground will create an enormous amount of heat and is probably what is melting his wires. Some welding machines work on this exact principle and use the electrical arc to create a very hot reaction which melts the metal, or welds the two metals together.

Maybe the guage of wire he's using is too small for the system he has?

Depends, kinda off, but as long at they are touching bare metal. If it's paint, you'll need to scrape/grind it away to make a clean connectionmisfitsfiend wrote:umm all my connections look fine pretty much, for my capacitor i have the ground going to the actual body of the car, and for the amp the ground goes to the strut... unless one of those was a bad choice im not sure :/

I assume you mean a strut MOUNT ...... which is entirely coated with rubber ............. an electrical insulator.misfitsfiend wrote:umm all my connections look fine pretty much, for my capacitor i have the ground going to the actual body of the car, and for the amp the ground goes to the strut... unless one of those was a bad choice im not sure :/
This location is fine if he is using what i think he is using, once paint is scraped its the best ground according to my multimeter, Likely due to the thickness of metal used for added support. As you can see both of my battery banks are grounded there.lakersfan1 wrote:I assume you mean a strut MOUNT ...... which is entirely coated with rubber ............. an electrical insulator.misfitsfiend wrote:umm all my connections look fine pretty much, for my capacitor i have the ground going to the actual body of the car, and for the amp the ground goes to the strut... unless one of those was a bad choice im not sure :/

Yes. That would be the strut MOUNT. That's what those four bolts go to. As said, if you didn't scrape paint off underneath the bolt, then it'd be useless and just grounding to the isolated strut mount. At least on some other bolts in the car, if you don't scrape paint, then at least the bolt would be going into something electrically coupled to the chassis.misfitsfiend wrote:yea not the strut mount, its the bolts that come up from the struts or whatever, the ones youd be bolting a strut bar to..

whats poor ground
A good example of poor ground would be Georgia Red Clay. Very poor ground. Hard to work, pathetic to grow anything in.
If you want very good ground, usually a high quality grass, such as zoysia, or anywhere where there is dense foliage would render good ground.
Usually called topsoil, however.
Moral of the story: If your wires are burning, put top soil in your car.
