When the starter motor is operating, the coil is fed with 12 volts from the starter. The wire contained in the primary ignition circuit Nov 18, 2024 · TR6 Petrol Injection. They provide resistance to reduce the amount of voltage going to your coil. Ballast resistance should match coil recommendation. 0. After rereading the previous post, if using a 12v coil, I don"t need a ballast resistor. The gt40r is for cars with ballast resistors. The ballast resistor/wire exists to prevent the coil from overheating during long term running. My understanding is the coil needs the ballast, not the ignition.
