Electronic Ignition Conversion Kit 12V Negative Ground for Allis Chalmers B IB C CA D10 D12 D14 D15 D17 G WC WD WD45 WF (Delco 4‑Cylinder)

This Ignitor Delco kit is a 12 volt, negative-ground electronic ignition conversion designed for 4‑cylinder Delco distributors. It replaces the mechanical points and condenser with a breakerless, solid‑state module that installs entirely beneath the original distributor cap, giving stable, maintenance‑free timing and improved engine performance. Typical installation takes less than 30 minutes in most cases. Compatible equipment: Allis Chalmers: B IB C CA D10 D12 D14 D15 D17 G WC WD WD45 WF. Also fits many other tractors including John Deere: 1010, 2010 (with 115/165, 3010/201); Massey Ferguson: TO20, TO30, TO35, 35, 50, 65; Minneapolis‑Moline: 5 Star, GB, GT, M5, M504, M602, M604, UB, UT; Oliver: 44, 55, 60, 66, 90, Super 44, 440, 550, 552, 900; White: 2‑44.

Key benefits and features: - Delivers approximately twice the voltage to the spark plugs, which improves horsepower, fuel economy and spark plug life. - Provides a 2:1 improvement over conventional points in current fall time for higher coil output. - Uses rotating cobalt magnets to trigger a Hall Effect integrated circuit — no points to burn and no moving parts to wear out. - Epoxy‑molded module resists dirt, oil, grease and moisture. - Compact design fits entirely inside the distributor — no external “black box” to clutter the engine bay. - Timing remains stable and requires no periodic adjustment. Recommended wiring: Use spark plug wiring set AC-4304D graphite carbon core Premium united packard wire. This conversion kit offers a straightforward way to modernize ignition on compatible tractors while preserving original distributor location and reducing routine maintenance.
