GC cable not nessasary need large diameter. Why nowadays all is called "multi-point grouding cable'?

Those GC cable main purpose is not carry high cuurent only, it actually connect the particular point and make it "fully grouded', AKA 0v. Ori car normally just have 1 or 2 grouding points from battery terminal to car body at the engine bay. Means our car body is actually in ground potential (0v) from +ve point of view. But does it really @ ground for whole chassis if the grouding point is at, let say th front of engine bay? The answer is NO.

Car body is constructed from joining all the panel. So from panel to panel, all are connected by bolt, and panel is not a perfect conductor. So when we connect, let say audio amp, normally shop will connect negative terminal to car body at cabin. However car body @ cabin is not nessasary equal to 0v, due to panel to panel resistance and resstance of the pnel itself. So when current flow from battery +ve to amp and loop back to battery -ve through car body, voltage drop exist across the panel, let say 1 volt voltage drop across the panel, means now from the point of view of amp +ve terminal refer to amp -ve terminal, the effective voltage across the amp is just 11v, as 1v is drop by panel, result? amp is not running at optimum level, therefore performance will drop. Imagine if all the electrical devices in car such as spark plug, lamp etc also use this kind of connection, what will happen is the performance will reduce.

Therefore this is where the GC play its role. By connect all those GC from battery -ve terminal directly to multi points such as engine block, firewall etc, is to make that point directly grounded same as battery -ve to ensure the ground current can loop back to -ve as short as possible, so that voltage drop across ground loop is eliminate and ensure electrical devices to run @ max performance.

So even our stock ground cable is huge ass cable also useless if the grouding point is just at one particular point.

In simple word, the correct way to connect in car electrical device is connect -ve to battery -ve directly by wire rather than connect to car body, this is what assesories shop refuse to do due to extra cable cost, let say if ur amp is located @ boot.

i think we missed out the important point which is purity of the copper
of course if we rich can try use 100% silver?

You don't sell armrest ka Siuyi? Or anyone who sell that type? Wanna start asking around

GC point is not connect likely actually. Normally working point will be engine body, alternator body, firewall, gearbox (auto), if there is extra cable can go to left/right/front body. After install those cable, feel the engine very smooth and quiet. If connect to body, sound system will improve so so much. Never try never know, once you try my Edge installed car you will get all your answer you want from the car not me.

My 1st charge, only the VS without the battery. As soon as I disconnect the VS from the charger, it quickly discharge by itself.

My 2nd charge, I attached the VS on my car battery, and charge both together with the static charger. After 2 hours, even I disconnect the static charger, the VS does not quickly discharge as it hold by the power of the car battery.

haha,
what im asking here is does the thickness, purity, material and direct connection or indirect connection to the -ve terminal a factor of reducing the GC's performance or not?

this question from coolkwc not you my friend. Read clearly what you write yourself 1st. And read post 261#

Then ma story end lo, bcoz both VS and bat3 also will self discharge de ma

I use phone to type all this, so i can't draw, u just try to imagine.

1. from +ve batt cable to device +ve, device -ve cable to panel A, grounding cable from panel A to -ve of batt.

so now voltage drop is exist in cable from +ve batt to device, cable from device -ve to panel A, and grouding cable from panel A to -ve of batt. You see, actually ur whole connection about this device involve 3 cable system, grouding cable is just one out of 3 cables from these system. Let say all these 3 cable is same material and lenght, and voltage drop due to resistance of these cable is 0.5v each cable, means effective voltage for device is just 12-(0.5x3) = 10.5v.

Now u try to improve groudin cable, which i told, one out of 3 total cable, u use the highest grade and very thick cable for that, what u do is u successfully reduce until 0v for this cable, means now ur device effective voltage will increase by 0.5v to 11v, therefore performance improved.

So how about left over 2 cables?? Well, u can change to same grade as used in GC too, but the cons is expensive and impractical.

Like what i said just now, eliminate groudin cable, and connect device -ve directly to -ve battery, while upgrade whole cabling sytem using better quality cable also can improve performance significantly.

If u understand what i said, a electrical device connection is just a loop, GC is just a terms to diffentiate it potential is at "ground" from -ve, thats all.

Theory finish, quick answer to ur question.
1. Thickness, material and lenght does affect.
2. 5-(-) batt is way better than 5-1-batt, now u are now bikin extractor wei

U reminded me why I study IT instead of engineering    It's like studying my Basic Electronics textbook again

I'm at the exact opposite side, my lecturer said I should have gone engineer instead of computer science because I brain in PICTURE. If you know what I mean, you start to draw diagram in your mind from what coolkwc wrote, then its easy to understand

How insulted u wor  I choose IT because my maths epic fail. If I become an automotive engineer and work in Proton, you car explode dy 

You choose your major for different reasons ma 

I don't know I reach magician in the morning, as I told him about sg999 case, he started to explain the VS thingy, then suddenly the "training" program struck my mind. Therefore we train the VS and the result lasted until just now I got home

Anyway, if tomolo it become lag again, then my theory of training wouldn't work liao

The trouble is, I don't drive that car often So, its haily possible by tomolo the VS ady drained/normalized by the battery liao
Refer the above, I guess the real effect is the huge ass welding cable that provide stable current that can charge up the VS every day, that's what I have in mind and wanted to make it my priority
1) Last month I draw a diagram, get the electronic shop unker make me a set of delayed key ring light timer+auto off with key switch, I burnt a few strip of LED with that useless board, thats exactly the same day kenjilew come ask me whether my "project" success

2) Last week, I submitted my 2nd draft of diagram to the unker, make me another set of delayed key ring light timer+auto off with key switch, I set the board on fire luckily got fire extinguisher

So, you and me both Ipork home boi open a shop, then I go and burn other people's bulbs and set their car on fire whilst you're trying to fix it

You need something to discipline your driving from aggressive to gentle. Now you wish there's a switch for you to turn the car from sport mode to unker mode. You need our product!!!
4) You're neither a racer nor unker, you just hope the sluggish throttle feeling go off. We all agreed that Plotong did a pissed poor job on the engine response. We have preset just right for this kind of driver. You need our product!!!
5) Last but not least, you wish the car have more bling-bling in the cockpit, so it looks like a fighter jet. The user control interface will project preset information/voltage display in LED that makes your car look exactly like a space shuttle. You need our product!!!

There's 5 type of drivers in the world. Regardless who are you, how old are you. You need our product!!! Quick! While stock last!

Uncle david said will sagat and the worst part the shop kaki tipu...so, cancel my intention to buy...

Hey guys....any VS is quite good for saga flx?....is it eric selling will be better?...or  EDGE VS Car Voltage Stabilizer ?^^anyone cna give me some suggestion?

haha.....erm.....^^i dont have so much money....^^to buy both...erm..i buy pivot mega raizin..after 2 yrs i use then i give you..^^all cap lifespan is 2 yrs...^^

Mix breed and get Mickey Mon!

but in malaysia with such PMS weather, I think its kinda hard to maintain the Airbag. Cold, Hot, Humid... causing the bag gets thinner and thinner i guess...
