Description
Overview:
The H.T. Coil (High Tension Coil) is a genuine Wipac part for Wipac ignition systems used on JAP and Villiers industrial engines. OEM reference S4775. It converts the low-voltage output from the magneto into the high voltage needed to fire the spark plug, helping engines start cleanly and run smoothly. Built around copper windings and a laminated iron core with robust insulation, it is designed to cope with heat, vibration, and continuous duty. Supplied as unused vintage old stock, so minor tarnishing or shelf wear may be present without affecting performance. This coil is suitable for maintaining, repairing, or restoring older machinery powered by JAP or Villiers engines fitted with Wipac ignition, including plant, agricultural, and garden equipment.
Key Features:
- Genuine Wipac part for assured compatibility and performance (OEM S4775)
- Direct replacement for Wipac ignition on JAP and Villiers industrial engines
- Quality copper windings and laminated core for a strong, consistent spark
- Durable insulation resists heat, oil mist, and vibration in harsh environments
- Helps cure weak spark, misfires, and hard starting caused by tired coils
- Correct mounting points and terminals for straightforward like-for-like fitting
- Suitable for routine service work and period-correct restorations
- Unused vintage stock: cosmetic tarnish or light aging only, fully functional
- Supports reliable running at idle and load for improved fuel efficiency
- Engineered to original specification for long service life
Typical Applications:
Used on stationary and portable equipment powered by JAP or Villiers industrial engines with Wipac ignition, such as cement mixers, compactors, generators, water pumps, saw benches, rotavators, and mowers. Ideal for workshop repairs, field service, and classic machinery restorations where dependable ignition performance is required.
