Standard Motor Products Ignition Sensor Assembly For Harley 1980-1995

OEM Quality and Precision Engineering

Standard Motor Products (SMP) has been a leader in automotive and motorcycle electronics for decades. This Ignition Sensor Assembly (replaces OEM #32400-80A) is a direct-fit part that installs perfectly inside the engine’s nose cone. The sensor utilizes a precise magnetic pickup to track the position of the ignition rotor, ensuring that your ignition module fires the spark plugs at the exact millisecond required for peak engine efficiency.

Built for Extreme Heat and Vibration

The ignition sensor is located in one of the harshest environments on a Harley-Davidson—the nose cone, which sits just inches away from the exhaust and cylinder heads. This SMP assembly is built with high-temperature wire insulation and a reinforced sensor housing that resists the “melting” or “oozing” failure common in older factory units. By utilizing superior potting materials, this sensor remains stable even during long-distance summer rides.

Solve Common Ignition Failures

If your bike runs fine when cold but starts cutting out or misfiring once it reaches operating temperature, the ignition sensor is the likely culprit. This electronic pickup plate replaces the aging sensor and wiring harness, eliminating the intermittent connections and thermal breakdown that plague older Harleys. It is the most cost-effective way to restore factory-level reliability without the need for expensive aftermarket programmable ignitions.

Installation and Fitment

This is a “plug-and-play” style replacement that uses the factory-style wiring. It is designed to fit the following models:

• Harley-Davidson Big Twin (1980–1995): Fits Shovelhead and Evolution (Evo) models including Softail, Dyna, and Touring.
• Harley-Davidson Sportster (1980–1993): Fits Ironhead and early Evolution Sportster models.
• Replaces OEM Part Numbers: 32400-80, 32400-80A, and 32400-80B.
