Both positive and negative battery are grounded
Hate to Ask but... Proper negative wiring for the boat
I did learn in the beginning that your electronics go to a + Positive and - Negative bus bar. Not to the boat itself. Looking at my 2012 Thunderjet: Both motors are grounded to the boat itself. The positive and negative go from the motor to the battery directly. No other wires touch the aluminum hull.

How To Properly Ground A Car Battery: The Definitive Guide
Which cable indicates the ground of a battery? The negative cable indicates the ground connection of the battery and is mostly connected to the chassis of the vehicle which can be removed easily without the creation of a spark. As a tip, always disconnect the live battery''s positive terminal first before disconnecting the earth terminal.
Why a double fuse is used in some applications?
As such, if the positive bar develops a fault to ground the current will circulate only in the upper half of battery stack. Likewise, if a ground fault develops on the negative bar the current will only circulate in the lower half of the battery stack. As such, both positive and negative need fusing. In this picture below the loads are ...
12-Volt Electrical Systems: Grounds Explained
A 12-volt automotive electrical system may sometimes be called a negative-ground electrical system.

Jump-Starting Your Car Battery | Instructions & Videos
Find the batteries and their terminals. Each battery has two metal terminals. One is marked positive (+), the other negative (-). There are also positive and negative cables in the jumper cable set. The red one is positive (+), the black one is negative (-). Never connect the red cable to the negative battery terminal or a vehicle with a dead ...
Ignition Coil Basics
This is the terminal that receives voltage from the battery. The primary wire is then coiled around the iron core and its other end is attached to the terminal marked "-" or "Dis." The voltage flows from this terminal to the breaker points inside the distributor. (Positive ground is the reverse.) Failures and Fixes
Positive or Negative Ground
Generators can be polarized to work either polarity. Some generator regulators are marked "negative ground" some are marked "positive ground" and some are marked "works on positive or negative ground." Modern alternators, unless specially modified are 12 volt negative ground. Starters turn the same direction regardless of …
Is Ground Same as Negative? Beginners guide
While it''s technically incorrect to refer to the ground side of the circuit as negative, most folks (including me) use both words interchangeably, as the ground side of the circuit leads back to the negative battery post. ... How Does a Ground Circuit Work? Voltage leaves the positive side of the vehicle''s battery, and it has two goals ...
Grounding for a battery
In most circuits these days, "Ground/Reference" is the negative terminal of the power supply, but in some cases it might be the positive terminal. (Old 6 Volt cars …
What Happens If You Touch Both Battery Terminals Together?
A battery is made up of two terminals, the positive and negative. If you touch both battery terminals together, it creates a short circuit, which can cause sparks and even fires. ... you will create a circuit. This can cause sparks, which can lead to an explosion if the battery is not properly grounded. Always wear gloves and eye protection ...
Car battery charging: a few questions on connecting negative …
You should attach positive first, but, also, you should only plug in the mains after you have connected both positive and negative, so does the negative have a higher risk of sparks? Is the risk of a spark real only with chargers that use more than 7-8ish ampere? Is it safe to attach a negative clip to the negative battery if the charger is 4A?

How to Tell Positive and Negative on a Car Battery
Instead of having the bright red color, negative car battery terminals have a black rubber cover. In some cases, vehicles will have black wires running to the negative terminal too. Unfortunately, some vehicles won''t have a rubber cover over the negative battery terminals. Furthermore, some vehicles might use black wires for both battery ...
When a battery is your power source, what is ground?
The common convention is to pick one node in the circuit and call it ''ground'', and then all voltages are specified relative to that. With a microcontroller, the …
When jump starting a car, can I attach the negative cable for the …
If you have both leads connected and you place a spanner on the positive clamp to undo it first, then EVERYTHING around that clamp is wired to the negative terminal of the battery. If you push the spanner too far, or it slips, and comes into contact with some part of the car while it is still connected to the positive clamp then a huge …
What is the purpose and difference between Positive and Negative Ground ...
SunPower used to make only positive ground solar panels. Due to very technical reasons, they were more efficient. They needed a positive ground charge controller to use them. They make negative grounded panels now, I can''t think of any reason to use a positive grounded controller these days.

Mobile DC Power: One Fuse or Two? • AmateurRadio
A Floating DC system would require a fuse on both Positive and Negative because neither has been grounded, plus a GFD circuit. Gets expensive and why we have Grounded Systems. ICOM provides two fuses for hams who demand to terminate both polarities directly to the battery to protect them from themselves.
Positive ground simplified
Alternators require negative ground too, if you are planning a conversion for more output. Negative ground is more common and less intimidating so it''s a popular conversion for formerly positive ground cars. Thus we now have a mixed fleet, with classic cars (and Frogeyes) set-up for both positive and negative ground.
Eli5: Why do we consider the negative terminal of battery …
With a positive grounded system, the corrosion tends to want to be where loads connect to the frame, where with negative, the corrosion tends to happen at the negative battery …
