Question about Cars & Trucks
Need diagram of Original 65 engine, convesion to newer HEI ignition system.
Dead simple. Old system used a resistor wire between ign. switch and coil. HEI does not need this so you need to run a 10 or 12 guage wire from the ignition switch "ON" position to the new coil with no resistor in between. This also means you no longer need the extra wire from the starter to the coil which was used to bypass the resistor wire in the old system to provide full 12 volts for starting car. The reason for the resistor wire in the circuit was to reduce the voltage to the coil once running so the amps in the spark would be higher to burn more thoughly and increase fuel mileage.
