Why does your VW have an ignition coil?
Most modern vehicles have ignition coils that connect directly to the spark plug. Older vehicles have a coil with a high-voltage cable coming out of the top. That cable connects to a distributor, when then distributes the high voltage current to each spark plug. Why Does Your VW Have An Ignition Coil?
What should the voltage be on a car alternator?
12.6v is the optimal battery voltage. 13 -14v is the average alternator output. Depending on the load on the electrical system, anything higher than battery voltage is good voltage for a vehicle. Current is a different story.
What happens if you have an ignition switch problem?
However, if your car has ignition switch problems, you may not be able to start the car at all. Ignition switch problems can also cause issues on the road, such as unexpected shutdowns or electrical problems. To be sure, ignition switch problems are no fun, especially if they’re stopping you from getting to work or school or play.
Why does my car voltage drop when idle?
• At idle, vehicle electrical loads may exceed the low speed current (amperage) output of the generator and when this happens the shortfall comes from the battery. This will result in a drop in the electrical system voltage as the battery delivers the additional electrical current to meet the demand.
How many secondary volts are in a primary ignition?
Nowadays, primary voltages are typically multiplied to around 40,000 secondary volts, depending upon engine operating conditions.
What does it mean when your battery is reading 0 volts?
If your battery is: Reading 0 volts, chances are the battery experienced a short circuit Cannot reach higher than 10.5 volts when being charged, then the battery has a dead cell Fully charged (according to the battery charger) but the voltage is 12.4 or less, the battery is sulfated
What should the voltage of a battery be when it is fully charged?
Cannot reach higher than 10.5 volts when being charged, then the battery has a dead cell Fully charged (according to the battery charger) but the voltage is 12.4 or less, the battery is sulfated Sulfation is the natural byproduct when the battery discharges.
Why are spark plugs lower in a rich ignition?
With a rich air/fuel ratio, spark plug voltages tend to be much lower because of better ionization. We can see that happen on an ignition scope because lean mixtures tend to drive the ignition spark line higher on the voltage scale while rich mixtures tend to drive spark lines lower.
