Coil + to ground voltage.....should it be constant?
The coil is an inductor. The longer it has voltage applied to it the windings will charge up and saturate, showing a steadily increasing voltage up until it matches the applied voltage. Additionally, if the points (or switching module) are open the coil is not grounded and you will see the system supply voltage (12V) at the coil primary terminals.
Identifying Car Battery Positive & Negative (+How to Jump-Start)
A car''s ground is not a battery terminal at all! Ground refers to any unpainted metal surface on the car which acts as a secondary negative connector. ... Corrosion usually occurs on the negative pole or positive pole of the car battery terminals. Battery corrosion is caused by electrolyte vapors escaping from the top of the battery ...
Electronics Schematics: Ground and Power Connections
Then, the voltage at the positive terminal of the first battery will be +3 V relative to the voltage at the negative terminal of the second battery. But, the voltage at the positive pole of the first battery will be +1.5 V relative to the point between the batteries, and the voltage at the negative pole of the second battery will be –1.5 V ...
Grounding for a battery
Given a 9V battery as the only voltage source for a circuit, where is the Ground usually put? Is there a standard, for example, that puts the negative terminal at 0 and the positive at +9? ... (Old 6 Volt cars were often "positive Ground", but negative ground is common now.) In many analog circuits, "Ground/Reference" is the center point of the ...
electron
It depends on the situation you refer to.The ground in a DC battery circuit is the negative point(-).The - of the battery is the most negative because there will be located more electrons, who,as you said,flow towards the positive terminal in order to equalize the number of electrons of both points.
Normal resistance between positive and negative leads when battery ...
Install the battery in the vehicle, have someone in the seat ready to crank the motor. Watch the voltage drop on the battery. If it is a fully charged good battery at 12.6 volts it should drop no lower than 9.6 volts while cranking. If the battery completely drops dead to the 1 volt you were saying the battery is bad and a new battery is needed.
Why doesn''t connecting a positive terminal of a battery to ground …
There''s a tiny deficit of electrons on the battery''s positive side, but once that equalizes (very quickly) there''s now a tiny surplus of electrons on the battery''s negative side. …
voltage present between Battery Positive and Chassis (metal) …
Normally if you check from battery positive to chassis ground, assuming the battery negative is tied directly to chassis ground - you''re going to see the battery voltage. If you''re looking for a short circuit - we can''t see or test your circuit from here.

my new battery when dead after 2-3 weeks in the garage. the system is charging at 14.2 volts,but when i checked for a drain the amp meter was at 100ma,and either terminal disconnected at the battery reads battery voltage.do i have a bad ground or is power bleeding or feeding into another circuit?When i disconnect the ip connector my amps go to …
batteries
Every piece of electronics whether it be a microprocessor or LCD screen always has a positive power supply and a ground pin. The positive power supply or VDD is clearly where you supply something like 5 volts. It would be like taking a 5 volt battery and connecting the positive end with a wire to the VDD pin.
Does Ground Wire Have Voltage? (5 Reasons Explained)
Stray voltage is leaking from the hot wire to the neutral or ground. These leaks are problematic. If these wires touch each other, you could short your system. A ground line with voltage can shock people if they touch grounded objects. 2). According to this ESP Surge X White Paper, you can blame N-G voltage on voltage drops. Even though copper ...
Ignition coil polarity
Because the output spark is very much higher voltage (20,000v) than the car battery (12v), it doesn''t care if the battery polarity is helping or hindering by a meager 12 to 14 volts in battery potential. ... These are more no-brainers, as you only need to match the terminal markings to the battery posts. For positive ground the "+" terminal ...
When do I connect to negative terminal or ground?
There are only two conditions where direct power connections to the battery negative are acceptable, anything else is risky. (1)- when the device''s internal circuitry fully isolates the negative power lead from the cabinet and all other external ports or leads exiting the device (2)-when the device''s external connections completely and reliably float from ground, and any …

ELI5: Where does ground go in a car battery? : r/explainlikeimfive
Electrons move from negative battery pole to the positive pole in a circuit. The "ground" has a different meaning compared to normal household electricity (alternating current). Nearly all cars/vehicles since the second world war are "negative ground", meaning all the chassis is "grounded" - connected to the negative battery pole.
positive ground battery system??
Positive ground means that the cable attached to the positive post on the battery (the big one) attaches to GROUND (the engine block, and a smaller braided strap to the chassis/body) on the other end and the NEGATIVE cable runs from the negitive post on the battery (smaller) goes to the starter solenoid, where that current is distributed to the starter …
A multi-cell battery management chip voltage sampling circuit with ...
There are two problems with the traditional lithium battery voltage sampling circuit based on operational amplifier voltage conversion: First, the use of more high-voltage MOS transistor in the operational amplifier leads to the reduction of detection accuracy; Second, there is a current path from battery positive to the ground during voltage detection, and the …
Ignition coil polarity
The simple fix for this is to reverse the two primary wire connections on the ignition coil. Because the output spark is very much higher voltage (20,000v) than the car battery (12v), it doesn''t care if the battery polarity is helping or …
Positive Ground Wire
+ lead on the positive post and - lead on the negative post usually just gives you a number. Use this to verify whether your polarity is reversed. I''ve never seen a 12 volt GM system that was made to be positive ground. Even the six volt cars of the 40s and 50s were negative ground. On the other hand, Fords used positive ground up through 1955 ...
Working With a Positive Ground
Many domestic car companies had positive ground systems right up into the ''50s. Ford changed back to a negative ground shortly before they went to 12- volt systems in ''56. Chrysler products also used positive ground on their six …
eli5: ground vs negative terminal. are they the same thing?
Not necessarily but, by convention, generally yes. Ground is nothing more than a baseline reference for all the voltages on a circuit. You start with whatever voltage your power source …
jump starting a 6 volt positive ground car
I use a 6 / 12 volt battery charger. You might need a 100 foot extension cord. But seriously, I think if you can keep a 71-year-old 6 volt positive ground car on the road, you shouldn''t need a battery pack - you da man.
Ignition Coil Basics
The coil becomes a transformer, stepping the voltage up. If your car uses a 12 volt battery, the 12 volts you put into the primary side of the coil will exit the secondary side as 30,000 volts! The high voltage is carried away from the coil by a high-tension cable that looks like a short piece of spark plug cable and runs to the distributor tower.
voltage
But, there are many circuits that work differently. Some circuits need a negative voltage, so the positive side of a battery would be "ground". Some circuits need positive and negative voltages, in which case there could be two batteries, one with the negative side attached to ground, and the other with the positive side attached to ground.
batteries
So each battery negative is connected to the chassis, you could control the negative instead of the positive but it does depend on the total of what you want to achieve and not with that particular relay which has an …
DC Voltage Polarity and Current Flow?
In a DC circuit, there is a negative (-) and a positive (+). I am aware that in electron flow theory, current flows from the negative (-) to positive (+). See Figure 1. But in a car battery, the positive terminal is considered the hot lead and the negative terminal is ground.
Accidentally touched positive battery terminal with...
Its not the voltage that''s dangerous, its the amps. Voltage is like pressure and Amps are like volume. The static electrial shock one gets after shuffling their feet on a carpet is thousands of volts but a tiny fraction of an amp. A car battery has only 12 volts but 550 or more amps. That is more than enough to kill.
voltage
On the other hand when a car is positively earthed then it convenient taking off the positive terminal first.For instance, when a car is negatively earthed and you disconnect the positive terminal, it means the whole body of the car is conducting,(because the negative terminal is attached to the body)If there should be a mistake by using a ...
Should Negative on Battery Bank Be tied to Ground?
When you ground the battery bank (negative battery bus ground bonding to ground rod/cold water pipe/etc.) it makes sure that the negative terminal can never get above zero volts. So shorting the negative wiring cannot cause a "short circuit" or over current situation and you only need fuses/breaker in the + leads (DC input to inverter, any 24 ...
ground
Assemble a few examples like the circuit you were given, and measure the voltages using different "ground points." Use the minus pole of the battery, then the plus pole of the battery, then some point in between. The sum will always be your battery voltage, though the measured voltages will depend on the resistor values.
