Electronic Ignition Kit Replaces PerTronix Solid State Ignitor 91241LS

Stop chasing faded sparks and messy point adjustments. This SherryBerg electronic ignition kit upgrades your classic ride by completely replacing the outdated PerTronix ignitor. You get reliable starts and smoother tuning without the daily guesswork.

Crafted specifically for vintage trucks and cars equipped with Ford Motorcraft Capri X‑Flow distributors, this solid‑state system bridges original styling with modern electrical accuracy. The module works immediately with any 12 volt negative ground setup and standard induction coils. Adaptive dwell locks in peak energy across your entire RPM range, which sharply cuts transmission misfires and delivers roughly double the available plug voltage compared to aging stock units. Because the circuitry reaches peak current right before the spark fires, your coil stays cool while lasting significantly longer. It also detects engine cranking and quickly pumps extra power for instant cold starts. If accidental backfeed occurs, the built‑in reverse polarity and over‑current protection safely shuts everything down to protect your restomod wiring.

Benefits & Tips

• Maintenance-free tuning. Once wired and timed, you will never need to inspect, sand, or replace mechanical contact points again.
• Maximize highway cruising. Pair the unit with a super low‑resistance 45,000 volt coil to unlock cleaner torque at high engine speeds.
• Avoid signal noise. Always route suppression‑style or spiral‑wound spark plug wires through the system to prevent electromagnetic interference.
