## Do you need a resistor with a 12 volt coil?

If a 6 volt ignition system is converted to 12 volts and a Delco style 12 volt coil with an internal resistor is installed as part of the conversion, no external resistors are required.

The 12 volt battery must be connected so the negative (-) battery terminal is connected to ground..

## How many ohms should a 12 volt coil have?

Most ignition coils should have a secondary resistance falling somewhere between 6,000 to 10,000 ohms;however, refer to manufacturer specifications for the correct range.

## How do you test a 6v ignition coil?

Connect one probe to each of the terminals and read the resistance. On a 12V coil, you should read between 3.1 and 3.5 ohms resistance. On a 6V coil, you should read between 1.43 and 1.58 ohms resistance. If you read zero resistance, you have a short in the coil and it is not functioning.

## How do I know if my coil is 6v or 12v?

You need to connect an amp meter in series with the coil and 6 volt battery. A 6 volt coil will draw 4 amps. If you have an accurate ohm meter, reading across the posts of a 12 volt coil should be about 3 ohms. A 6 volt coil is about half of that.

## Do I need a resistor for my coil?

Does an ignition coil need a resistor? Although that’s not the case with EVERY coil, most do require it. The resistor limits the CURRENT going through the coil. Also, if you have a points ignition, it lengthens the life of the points greatly.

## Will a 12 volt coil work on a 6 volt system?

In other words there is no reason that a coil that was originally sold for use in a 6 volt system can’t be used in a 12 volt system. … 6 volt coils will generally have very low internal resistance built in, anywhere from . 5 to 1.5 ohms.

## Does a resistor reduce voltage?

Does a resistor reduce current and voltage? Absolutely! A resistor is about to reduce the current and voltage. For example, when the current flows through the resistor, it will always generate a voltage drop, and which is mainly reflected in the decrease of the output current and the voltage.

## What does a resistor do on a ignition coil?

In simple terms, the ballast resistor in a Mopar limits the amperage, or current flow, through the coil while the engine is running, thereby extending the life of the coil and breaker points of the distributor.

## How many volts does an ignition coil have?

The ignition coil is the component that converts the 12 volt signal into the high 20,000+ volt charge. Once the voltage is stepped up, it goes to the secondary circuit which then directs the charge to the correct spark plug at the right time.

## How many ohms should a 6 volt coil have?

The resistance should be 0.4 to 0.6 ohms.

## Are 6 volt and 12 volt condensers the same?

No such thing as a 6V or 12V ignition condenser. Irrespective of applied primary voltage (6V, 12V, 24V) the condensers are made to withstand the flyback or reverse EMF voltage made by the coil as it’s magnetic field collapses when the points open.
