Quick note on edit: this is how you wire the coil in any old car with a carburetor. Bug, Bus, carbureted Rabbit, 6-volt Bug, 1957 Chevy, John Deere tractor...all basically the same. All old cars use Charles Kettering's classic ignition system, which endured for decades because It's Cheap and It Works. Coils have three terminals: low-voltage +, low-voltage - and high-voltage. High voltage is in the middle; it goes to the distributor. Low-voltage + has two wires coming out of it, even though there are three prongs coming off this terminal. One wire goes to the ignition switch. The other goes to the automatic choke on your carburetor. The third terminal is a convenience outlet. Low-voltage - is for the condenser in your distributor. Don't hook anything else to it. ESPECIALLY don't hook it to ground!
12 volt
12 volts battery.
Six Volt (unless it's been converted).
Yes, when converting from a 6-volt system to a 12-volt system in a vehicle, you typically need to replace the coil with one that is compatible with 12 volts. This is because a coil designed for a 6-volt system may not be able to handle the higher voltage and could lead to issues with the ignition system.
Stock battery is a 6-volt unit. check VW specialty shops for replacement.
To wire a 12-volt coil, connect one terminal to the ignition switch's "hot" terminal and the other terminal to the distributor in the ignition system. Make sure the coil is grounded properly for it to work effectively in the circuit. Refer to the manufacturer's instructions or a wiring diagram for your specific vehicle to ensure proper installation.
The ignition coil on a car ranges between 3 and 5 amps, which it gets from a 12 volt battery. The battery produces DC current though the coil The coil can transform the low voltage of the batter to thousands of volts that are needed to start the car.
No. The ignition needs 12v to run, the starter needs 12v to crank, the bulbs all need 12v to get bright enough...
All Volkswagen Golfs, Jettas, and Rabbits use a 12 volt ignition system. So their cigarette lighters operate off of 12 volts as well.
If there is no spark at the coil despite 12 volts going in, it could be due to a faulty ignition coil, a defective spark plug, or a break in the ignition circuit. Additionally, issues such as a malfunctioning ignition module, a poor ground connection, or insufficient battery voltage can also prevent the coil from producing a spark. It's important to check the entire ignition system for any faults. Testing the coil with a multimeter can help identify whether it is functioning properly.
First, see if the each coil is getting the required voltage from the ignition switch (probably 12V). If they are, you can check the resistance of the coil with a simple volt meter. Should read minimal resistance. If the meter reads OL then the coil windings are open (defective/bad).
To check if a 12-volt ignition coil is bad, first disconnect the coil from the ignition system and measure the resistance between the primary terminals using a multimeter; it should typically read between 0.5 to 2 ohms. Next, measure the resistance between the secondary terminal and either primary terminal, which should be around 5,000 to 15,000 ohms. If the readings are outside these ranges, the coil may be faulty. Additionally, you can perform a spark test by connecting the coil to a power source and observing if it produces a strong spark when triggered.
