No. That's commonly known as a "big 3" upgrade, where you replace the wire from the alternator the battery positive, battery negative to ground, and engine block to ground. This will have to be done if you're adding any aftermarket devices with a high amperage draw (such as off-road lights or sound systems), as the factory wiring is intended for use with only the stock electrical system, and drawing extra amperage on the factory wiring can lead to fire. It's also a necessity if you plan on buying a high output alternator.
Normally, yes. The positive + post is larger than the negative.
If you have a post battery(the cable attaches from the top) the positive post is larger than the negative.
Always disconnect the negative (-,black, smaller) & then the positive (+,red,slightly larger). Installation is the reverse.
It doesn't matter whether you're jump starting a Van, pickup truck or an economy car, always use cables with the largest possible COPPER wire, 00 gauge or larger. Smaller cables will often provide enough of a boost to help a battery that's just a little low, but the larger cables work best for the more severe situations.
Larger.
the voltage of a battery could be larger than the emf if you are to charge the battery, in that case V=E+Ir .
Ribbon cables are mostly, but not always lower voltage signal carriers. Power cables are mostly larger and carry higher voltage to various parts tht need it.
Yes The larger the battery, the more voltage the battery has.
cables get hot because they have too much current running through them. heating wires are made to run hot. cables are not. get larger wire
The Fossil JR7978 takes two button cell batteries. The larger battery is LR41 and its a smaller battery 377. To my understanding the larger battery is for the time and the smaller battery is what powers the dial display.
If the battery has round terminals the positive is the larger diameter of the two
That will depend on the construction of the battery. Usually larger batteries have more power because they have larger lead plates inside.
