A magnetic pickup is the trigger that tells the ignition control when to fire, and a failing one shows up as a no-start or an intermittent misfire that comes and goes with engine temperature. This is the same high output assembly used in current Pro-Billet distributors, supplied with the two-pin connector already installed so it drops straight into place.

• Same high output pickup found in all Pro-Billet distributors.
• Maintenance-free design with no moving parts.
• Resistance of 600 to 1,200 ohms.
