Factory Ballast Resistor, 70-73 240Z

Factory Ballast Resistor, 70-73 240ZQuantity in Basket:none
Code: 12-4145

Available Again! Nissan discontinued these genuine, original equipment (OEM) resistors many years ago. We recently found a new supply of factory replacements. Get yours before they disappear!

The ballast resistor is designed to protect your distributor (the ignition points in particular). It sets the resistance in the ignition to 3.0 Ohms when combined with the resistance in the factory coil or 1.5 Ohm coils. In addition, it is needed to get an accurate tachometer reading when stock or 1.5 Ohm coils are used, as the tachometer takes its reading from after the ballast resistor.

Ignition Coil Note:
This ballast resistor should be used with stock ignition coils and 1.5 Ohm coils, such as our 1.5 Ohm PerTronix Flamethrower Coils. It should not be used with 3.0 Ohm PerTronix Flamethrower coils or Crane coils. For all others, check with the specific manufacturer for whether a resistor is required or not.
