Problem fusing my grounds

Is there lollypops and gumdrops also, where you are from.

yes. There aren't in retard land where you are? Yeah I guess that makes sense, you wouldn't get it through the facemask in your helmet and if you did you'd choke on it.

Sure ya do pal.

Dude, I've forgotten more about automotive anything than you'll ever think of knowing.

Ok, no need to fill up your drool bucket too fast.

lol CLEARLY... idiot.

Hi, I'm having trouble getting the hooked end of my fuse to wrap around the negative battery terminal. Could someone explain the technique for this?

Its your thread, I only post in it.

wow will someone just ban this idiot already. he's already called himself a liar then immediately lied about that. he has his answer and still pushes on with this ******** he deserves to get banned just for being an incompetent a-hole. as well as wasting our time

ok. since no one yet seems to understand why we only fuse power wires, let me explain.
first, lets all recognize that the convention for DC current is backwards. DC current "flows" from negative to positive. ok, let's move on.

Regardless of current (charge flow) direction, we still recognize that power wire is fused to provide two things:

1. over current protection

2. short circuit protection

The DC electrical system in a car uses a common ground - i.e. the metal in the car. This provides a convenient ground for all of the various electrical components in the car, saving money and weight.

In order to protect the battery, only one of the wires (power or ground) needs to be fused. We fuse each power wire because those are the wires that are dedicated to each load. If you fuse the battery ground lead at the battery, it would be a ~300A fuse so it could handle the starting current as well as every single piece of electronics in the car. let's think about what that would do - it certainly wouldn't provide over current protection for anything, and various wires in the car would melt before the fuse blew due to a short (assuming that was the only fuse in a circuit). If you fuse your ground in addition to fusing each power wire - the only thing you will accomplish is increased voltage drop. the positive wire fuse will certainly blow first, unless of course that wire is the same ampacity as the ground fuse (i.e. for 1/0 wire or something).

We size the fuse for each power wire based on the wire size, and we size the wire based on the ampacity (load) of each device that wire serves. positive wire fuses can be selectively sized for each wire in common locations (battery, fuse box). if you were to fuse each ground wire - it would be between the electrical device and the metal on the car and located all over the place. that would be effective but annoying.

you want wires fused as close to the source as possible - in this case the battery positive terminal or fuse box. by fusing the power wire you are protected from any short circuit that happens on the load side of the fuse. if power wire comes in contact with the car metal, the circuit is completed, current leaves the negative terminal - flows through the ground wire to the chassis - contacts the short location and travels down the power wire trying to return to the battery - but it first passes through the fuse which opens the circuit - and the battery is protected. you may try to argue that fusing the ground allows the fault to clear faster - but that depends on the size of the fuse. the difference in time would be so short, there really is no benefit.

fusing the ground is pointless due to the size of fuse required... and it's redundant since the power wire fuse already protects the battery. you only need one fuse in the DC circuit.

lastly, the only fuses that are directly connected to a battery terminal are inherent to the battery terminal. Streetwires has some that use AFS fuses. otherwise, you still need a protective fuse holder and a short lead of wire to the battery terminal.

cliffs:

you only need one fuse in the circuit

fusing the positive wire is sufficient and effective

fusing a ground wire won't hurt anything unless it blows while starting the car and you're left stranded

tl;dr

You're an idiot. You do not understand electronics. I did not call myself a liar. I proved that you idiots don't know what you're talking about. You cannot short ground to ground. Does that make fusing the ground ineffective? No contrary to what you idiots might think. There is nothing wrong with shorting a ground to a ground. If you short a positive to a positive does the fuse blow? No, it's the same thing as shorting a ground to a ground. It does not matter which one you put the fuse on, and the fact that you idiots didn't know that shows that you're all tards.

But it DOES make you stupid.

I'm with the OP...

Myself, I've not only put circuit breakers inline with my ground returns.. but I've started adding fuses to the chassis and body panels of my car... I just take ANL fuses and screw them down, everywhere... you can't be too safe... //content.invisioncic.com/y282845/emoticons/graduate.gif.d982460be9f153bb54e5d4cb744f6ae8.gif

i want to rant on the childish nature of this name calling, but it's a waste of my time.

carry on i guess...
