The distributor switches on the low side of the ignition coil (-), usually a black wire. It should read ~13 V (battery) with the points open and ~0 V with the points closed (grounds it to the block). The other side of the coil (+) is usually a green wire. It should read ~13 V when the points are open and drop to ~8 V with the points closed (unless ignition switch held in start position, bypassing the ballast resistor). If converted to electronic ignition, there are other wires and the points (or pickup) acts as just a sensor signal.
What else can I help you with?
Is the ground wire positive or negative?
Neither - it's neutral !
Which wire is negative and positive on a starter?
positive goes to the battery and negitive goes to a ground clamp on the frame..
What side does electrons flow from in a battery?
Outside the battery:The path for conventional current goes from the positive terminal (+, usually a red wire) to the negative terminal (−, usually a black wire).A wire's electrons flow from the negative (−) terminal to the positive (+) terminal.Since the current forms a continuous a loop in the same direction, the direction inside the battery is "backwards".Inside the battery:Conventional current flows from the negative (−) terminal to the positive (+) terminal.Positive ions flow from the negative (−) terminal to the positive (+) terminal.Negative ions flow from the positive(+) terminal to the negative (−) terminalConventional current assumes that all flowing charges are positive. It simplifies the situation because it hides the more complicated electrons, positive ions, and negative ions.
How do i wire a 12 volt cigarette lighter plug on to a device like a c.b.radio?
On American cars the positive lead from your cigarette lighter is in the center of your socket. The adapter plug has the positive lead on the tip of the adapter and the negative lead on the side of the adapter. You need to use a volt-ohm meter to find out which wire comes from each lead. (You may be able to open the adapter and follow the wires that way).On the c.b. radio the positive lead should be red. This will connect to the positive lead on the adapter. The black lead on the c.b. radio is the negative lead. This will attach to the negative lead on the adapter.P.S. Usually the adapter will have a fuse built into it to protect from incorrect wiring.
What causes battery to spark and jumpers to melt?
The current passed through them was too high. Possibly they are cheap cables, (many of them on the market today.) - Cables should be at least 10 gauge wire. Mine are 6. The thicker wire, the better quality your cables are. Anything thinner than 12 gauge is dangerous,.
How do you tell a positive speaker wire from a negative speaker wire?
The positive speaker wire is a solid color, your negative wire should have a stripe on it.
How do you wire a tachometer to a 1974 Valiant?
you can wireit directly to the coil... check for the positive and negative wires or there is also a place in your distributor.......
How do you connect the alternator positive and negative wire to starer?
You do not connect any wire from the alternator to the starter. The positive wire from the alternator should run to the positive on the battery, and the negative wire (if equipped) should run to the engine block (or any suitable ground). Most alternators are already grounded by the bolts holding them to the engine, but some do have a negative wire.
Which wire is grounded positive or negative?
The negative wire is grounded.AnswerThe negative wire is grounded.
What are the standard speaker wire colors for positive and negative terminals?
The standard speaker wire colors for positive and negative terminals are typically red for positive and black for negative.
How do you tell a positive wire from a negative wire on a car?
On the car battery, the positive wire is red and the negative wire is black. If the body of the car is metal or conducts electricity, then the body of the car serves as the negative wire. The metal in the engine serves as the negative wire.
Is the copper wire positive or negative?
copper is positive
What is the voltage reading of positive wire in 110V dc?
You should be asking, 'What is the potential reading of a positive wire....?', as 'voltage' means 'potential difference' and you can't have a potential difference on a wire! The positive wire has a potential difference of +110 V with respect to the negative wire.
What are the positive and negative speaker wire colors on a 2008 pathfinder?
The positive speaker wire is red while the negative speaker wire is black on a 2008 pathfinder.
Does the red wire go on the plus sign on a battery or the minus?
The red wire is Positive, (+) and the Black wire is Negative. (-)
Is the hot wire labeled positive or negative?
Hot is positive.
Where does the two wires coming from an accel distributor connect too?
The two wires coming from an ACCEL distributor typically connect to the coil. One wire is for the ignition power source, while the other wire is for the tachometer. It's important to consult the manufacturer's instructions or a wiring diagram to ensure proper connection.
