What is the reason for a positive ground system?
- Cranes
- Health-care facilities (some restrictions)
- Electrolytic cells
What are the tradeoffs for positive vs. negative ground?
Originally, the voltages on the wires were positive with respect to earth. This is called negative ground, since the negative side of the battery is grounded to earth. With negative voltage on the wires, in respect to earth, (called positive ground) the copper is protected from corrosion. Why is it important to ground?
What is positively grounded mean?
This means, that a system that has been installed according to common methods (without grounding or with negative grounding) and is suffering from decreased performance can be restored to full operational performance by wiring it as a positive- grounded system. Positive Grounding.
Why is ground system positive?
The positive ground extends the life of spark plugs. The electrons flow from the center to the edge of the plug. Then most of the damaging heat of the spark is put into the spark plug body and not the center electrode which has limited heat dissipation.
What is the difference between negative ground and positive ground?
This is also often referred to as negative ground, i.e. the negative line is used as the ground – also referred to as return or common – and the positive line is the “hot” line which carries the +12 or +24 volt potential.
How do you jump 6V positive ground?
Re: 6 volt, positive ground boost help?Disconnect the lead from the starter to the starter solenoid at the starter solenoid.Connect the 12V vehicle Positive to the 6V vehicle Positive.Temporarily clamp the negative booster cable to the starter cable to rotate the engine. Unclamp it once the motor starts.
How do you hook up a positive ground?
You should check the ignition coil polarity. For positive ground the + primary terminal should go to the points. For negative ground the + primary terminal should go to the ignition switch and the - terminal should go to the points. You will get better spark that way.

How do you change a negative ground to a positive ground?
How to convert your car from positive earth to negative earth: Make sure that the ignition to the car is in the off position before you start. Disconnect both of your battery terminal connections, and turn the battery around 180 degrees. If it is not possible to turn the battery, the cables must be lengthened.
Do you ground positive or negative?
Ground is an arbitrary reference point you can choose wherever you want. All other potentials in the circuit are measured relative to ground. So by definition, ground is at 0 potential and it is neither positive or negative.
Can you jumpstart a 6V with a 12V?
Can you jump start a 6 volt battery with a 12 volt? The answer is it is not recommended. However, if one wishes to perform it, the key to jump-starting a car with an incompatible battery is having the right cables.
Can you jumpstart a 6V car with a 12V car?
You can jumpstart a 6 volt with 12 volts, but the safe way to do it is with the key off. Use the 12 volt to impart a charge to the 6 volt battery and then disconnect it before you try to start the engine, otherwise you might fry your gauges and generator/alternator.

How to connect a negative battery charger to a negative battery?
Connect the negative, or black, cable from the battery charger to the negative battery terminal by squeezing the alligator clip at the end of the cable so that the jaws open. Place the jaws over the terminal and slowly release the clip so that it is firmly attached to the terminal.
What type of battery is used in a vehicle?
Although most vehicles use a 12 volt battery that negatively grounded, some vehicles that were still in use as of 2010 use a 6-volt electrical system that is positively grounded.
What does positive go to?
positive goes to the coil on a positive ground car like a Model A, 9n,2n, 8n Ford tractor, or anything Ford up to the 12 volt days. Negative goes to the coil on a negative ground car. Click to expand...
Can a generator be polorized?
Yes. it's known as 'polorizing the charging circut'. Generators put out DC current,with a positive side,and a negitive side. Alternators put out alternating current,switching positive,and negitive current,many times a second Diodes, act as a one-way valve,separating the poles. 'Sparky'
Can an ammeter be reversed?
Yes. The ammeter needle would be reversed. I know on my shoebox,when I changed to 12v neg. ground, I had to run the ammeter wire,the oppsite way through the loop, on the back of the gauge. Sparky
How is the ground potential determined on a tractor?
Keep in mind that the tractor frames ground potential is determined by what post of the battery is tied to ground. A tractor is only positive ground frame if the positive battery post is tied to the frame.
Does grnd go to the distribuitor?
Thus on the old setup, grnd went to the distribuitor, assuming that was positive ground. if you leave it negative ground.. you need to swap it over so it shows batt to the distribuitor.. However.. if it still has the old coil.. replace it. The newer oil filled coils provide much better high voltage.
Why do telephone companies use positive ground?
were Positive ground. Telephone companies still use it due to the fact that to change every telephone office and piece of equipment in the world would have to be changed at the same time due to the way they are interconnected.
How do generators change from positive to negative ground?
Generators are easily changed from positive to negative ground (and back...) by "re-polarizing" the field windings - sending a current of the proper polarity thru the windings for an instant. Ammeters ARE polarity sensitive - they will read "backward" if connected the wrong polarity.
What does the + pole mean in a battery?
The chemical action going on in a battery is shoving electrons to the - pole, and the + pole indicates the absence of electrons. Since electrons were deemed to have a - charge somewhere many years ago, the terminal or pole where all those little guys are hanging out get the - sign.
Can a 6V starter run 12V?
wire's are heavier gauge need shorter in length. generator would need poles wired for correct flow to charge. most 6v starters can run 12v if not overheated.
Can PNP transistors be used with NPNs?
There is very little to prefer the use of one versus the other until electronics came about. As we know semiconductor PNP transistors never caught up with the capability of NPNs, which in turn are easier to design with using a positive supply, particularly in switching electronics.
Is a positive ground the same as a negative ground?
Dax - A positive ground works exactly the same as negative ground. The ONLY difference is current in a positive ground system flows the opposite direction from current a negative ground system. Think of left hand vs. right hand threads - both accomplish the same thing only one tightens the opposite direction from the other.
Do mechanical voltage regulators work on ground polarity?
Also some mechanical voltage regulators are polarity sensitive. They may contain clamping diodes, arc suppression capacitors, etc. that work on only the correct polarity. However if a regulator is not marked for polarity it will work fine on either ground polarity. ----.
Why did the BMC Corp need more than positive earth?
The car needed more than positive earth to survive..BMC Corp needed more than the flow of electrons to rustproof their cars. Around 1967, negative earth became more popular and more common on all cars, especially British ones.
Do alternators need negative ground?
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.
Does every battery have a positive terminal?
Every battery has a larger positive terminal. You can see in the photos below that the positive terminal is slightly larger. So in the photo above, the battery above is wired for negatve ground, with the smaller terminal on the right wired to the firewall for ground and the fatter post wired to the starter solenoid.
