Datsun Roadster 12 Volt Ignition Module
Pertronix Electronic Ignition
Made for 12 Volt ignition systems. This Petronix unit can run at full 12 volts without a ballast resistor as long as the coil measures 3 ohms of primary resistance. We have coils available in this section that work with this unit. To check resistance on your own coil disconnect all wires to the coil. Put each wire from your Ohm Meter to each side of the coil and read the resistance. Do not eliminate the ballast resistor if the measurement is below 3 ohms. Read instructions carefully when installing. Much better than points. This is a great alternative.
