How does a 6 volt ignition coil work in a 12 volt system?
When a 6 volt ignition system is converted to 12 volts either a 12 volt coil must be installed or a resistor installed in the circuit to reduce the coil voltage to 6 volts. The resistor regulates the voltage, keeping it at 6 volts, allowing the original 6 volt coil to be used in a 12 electrical system.
Why does my ignition coil keep burning out?
Here is why! The leading cause of premature failure of an ignition coil is due to a worn or bad spark plug ignition cable. A bad spark plug ignition cable will have a much higher than normal resistance.
How many amps does an ignition coil use?
We know that a typical small engine ignition coil uses between 3 to 5 amps. By using the above mathematical formula we can determine that the bad spark plug ignition cable caused between 15,000,000 to 20,000,000 volts to be generated by the ignition coil!
What causes a spark plug to melt an ignition coil?
A bad spark plug ignition cable will have a much higher than normal resistance. This high resistance causes a very high amount of voltage to be generated from your ignition coil’s secondary winding. This excessive voltage creates a high amount of heat which consequently melts the coil’s wire insulation.

Why are some 12 volt converters having ignition problems?
This is a MUCH better design for getting rid of excess heat than the plastic case and potting compound used in the front mount coils. I believe the main reason many 12-volt conversions are having ignition problems such as weak spark or burned coils is directly related to the weaker square-can coils and the less-reliable replacements we are getting.
Why are my 12 volt coils not working?
I believe the main reason many 12-volt conversions are having ignition problems such as weak spark or burned coils is directly related to the weaker square-can coils and the less-reliable replacements we are getting. Buying a 12 volt conversion kit is no guarantee of success.
How much resistance does a 12 volt coil have?
The typical 12-volt conversion with either a 6 or 12 volt coil should have a total resistance of around 4 ohms. Any more resistance and the spark gets too weak for reliable starting.
