Mini Sports Coil - High Power - 3ohm
12 Volt high powered sports coil - 3ohm resistance suitable for non ballast ignitions (standard) systems.
What is the difference between Standard and Ballast ignition systems?
A Standard 12 Volt ignition has a standard ignition coil that produces a full power spark at 12 volts. A Ballast ignition has a ballast coil that produces a full power spark at a reduced voltage , the voltage is dropped by placing a ballast resistor or a resistor wire in the live feed to the coil. The coil will have a second feed running from the starter solenoid ,this will supply a full 12 volts on cranking giving the coil 125% the voltage it needs enabling a stronger spark at start up. Once the car is running the 2nd feed is cut and the coil will be powered by a reduced voltage.
How can I tell if I have a standard or ballast system?
Most British cars had a standard ignition up to early 1970s when replaced with the ballast system.
- Standard system will only have 1 wire on the + side of coil. (Not including any suppresser wires)
- Ballast system will have 2 feeds on to the + side of coil. (Not including any suppresser wires)
