The COIL HAS A POSITIVE AND A NEGATIVE TERMINAL. If you look at the top of the coil, it is generally marked + and - on the top.
Not necessarily. It means that is the component being effected. It may mean the coil is bad. The coil should be tested.Not necessarily. It means that is the component being effected. It may mean the coil is bad. The coil should be tested.
In this context, 'negative' and 'positive' are used to indicate the sense, or direction, of the induced voltages, as voltages do not have electric polarity (+ or -). The direction of the voltage induced into a conductor is determined by the direction of that conductor relative to the magnetic field. As the coil rotates, the directions of each side of the coil reverse relative to the field, and the induced voltages reverse too.
A diode connected in this way is a flyback diode or kickback diode. There are some other names that may be applied. The diode is a protection device. When power to the coil is discontinued, the electromagnetic field around the coil will collapse. The collapse of that field will induce a voltage, and this could expose circuit elements to "kickback" from the field collapse. The polarity of the induced voltage will, however, forward bias the diode, and it will conduct current for an instant. The inductive kickback of the coil will thus be damped by that diode.
There are a couple of examples that come to mind where there is a coil in a circuit. One is, the coil is used as a choke to block harmonics from going down the electrical line. Another example of a coil in the line is the coil in a magnetic contactor. When this coil is energized the contacts of the magnetic contactor close.
coil span or coil pitch is defind as the distance mesured in terms of armature slots(or armature conductors) between two sides of a coil.
Instal a swithhed direct line from the batterie to the positive side of the coil Instal a swithhed direct line from the batterie to the positive side of the coil
look at the coil, it is marked - or +
make sure the coil is a positive grounded coil, most are negative ground. battery just hooks up opposite to usual the coil is the only thing u need to make sure of
ignition
Your coil has a positive and negative side and if there is no power to the positive side you will not have any spark: However, if you have no ground to the negative side you will have the same problem. Check for power and ground with a volt meter.To check for power, connect red lead from volt meter to positive side of coil and black lead to negative side of battery, you should read 12 volts with key on. To check ground, connect black lead from volt meter to negative side of coil and red lead to positive side of battery, you should read 12 volts with key on.
To install coil wires on a 1967 Chevelle, first ensure the ignition is off and the battery is disconnected for safety. Identify the coil terminal for the positive (usually marked with a +) and negative (marked with a -) connections. Connect the positive wire from the ignition switch to the positive terminal of the coil, and then connect the negative wire from the coil to the distributor. Finally, double-check all connections for security before reconnecting the battery and starting the vehicle.

No, just the positive side is hot.
When the coil spring is completely compressed and the coils are touching
To maintain positive pressure in the AHU coil
To hook up a 6-volt positive ground ignition coil on a 1949 Ford tractor, first ensure the tractor's battery is disconnected. Connect the positive terminal of the coil to the ignition switch, and the negative terminal to the distributor. Make sure the battery's positive terminal is connected to the chassis ground, as the system operates on positive ground. Finally, reconnect the battery and check for proper spark when cranking the engine.
