Sierra 18-5450 Marine Coil Resistor, 1.5 Ohm & 3.0 Ohm, Replaces 3874767

The Sierra 18-5450 is a marine coil resistor rated for 1.5 Ohm & 3.0 Ohm applications, built to regulate voltage to the ignition coil in PleasureCraft ignition systems. It is machined for consistent, reliable performance and is sized to install into existing ignition wiring layouts without modification, at a compact 0.39 x 0.39 x 0.39 inches and just 0.06 pounds.

As a coil resistor, its job is to drop supply voltage to the level the ignition coil and points are designed for, protecting the coil from excess voltage during normal running while still allowing higher voltage during starting on systems wired for that function. The Sierra 18-5450 cross-references directly to OEM part number 3874767, making it a straightforward like-for-like replacement when an original coil resistor has failed or is being serviced.
