Compatible with Kohler 54 755 09-S Silicon-Steel Stator, 11-in Short Harness, Fits Old 237878-S 15/20 AMP System, Includes Fits Half-Wave Regulator 25 403 03-S & Tool Kit, No-Cut Install, by VOLTIZER

This VOLTIZER 54-755-09-S Upgrade Silicon-Steel Stator Kit is engineered for Kohler engines that use the old-version 237878-S charging coil system. Modern service coils come with 70cm harnesses designed for universal fitment, but they do not match the routing of older engine layouts. This kit restores the original 11-inch (28 cm) harness length, providing clean, factory-correct installation with no wire excess. The stator features an upgraded silicon-steel laminated core, improving charging efficiency, reducing heat, and delivering stable 15/20 AMP output across all operating speeds. Each kit includes a matching regulator and OEM-style terminals for direct installation without splicing. This kit replaces older Kohler OEM numbers 24 08 501-S, 24 08 503-S, 41 085 05-S, and 41 085 07-S, and is compatible with a wide range of Kohler engines using the old 237878-S coil configuration. Compatible engine families include: K-Series: K161, K181, K241, K301, K321, K341, K482, K532, K582 Command CH-Series: CH11–CH15, CH18–CH25 Command CV-Series: CV11–CV15, CV18–CV22, CV25, CV460S, CV461, CV490, CV492, CV493, CV730, CV735, CV740 Courage SV-Series: SV470–SV620 Aegis LH-Series: LH640–LH775 VOLTIZER products are engineered for long-term durability, stable performance, and precise compatibility with aging Kohler equipment. This kit is an ideal solution for technicians and homeowners seeking a high-quality replacement for legacy charging systems.

• 1️⃣ Upgrade Silicon-Steel Stator for Old-Version 237878-S Systems Built as an enhanced replacement for Kohler engines using the old-version 237878-S charging coil system. This 54-755-09-S stator kit restores correct charging performance for legacy engines where the modern 70cm replacement harness is not suitable.
• 2️⃣ Short 11 in (28 cm) OEM-Style Harness — Perfect Fit for Legacy Layouts Designed with the original 11-inch short harness, matching the routing of older Kohler engine compartments. Avoids the excess wire, difficult routing, and interference issues caused by today’s long 70cm service coils.
• 3️⃣ High-Efficiency Silicon-Steel Laminated Core Uses upgraded silicon-steel laminations, delivering lower magnetic loss, cooler operation, and stronger charging output than traditional cold-rolled steel stators. Provides reliable 15/20 AMP performance under heavy mower and tractor workloads.
• 4️⃣ Replaces Older OEM Numbers Direct replacement for old Kohler OEM numbers: 24 08 501-S, 24 08 503-S, 41 085 05-S, 41 085 07-S. Includes stator, regulator, and correct terminals for plug-and-play installation with no wire cutting required.
• 5️⃣ Fits Multiple Kohler Engine Families (Compatibility) Compatible with Kohler engines originally using the old-version 237878-S system, including: K-Series: K161, K181, K241, K301, K321, K341, K482, K532, K582 CH-Series: CH11–CH15, CH18–CH25 CV-Series: CV11–CV15, CV18–CV22, CV25, CV460S, CV461, CV490, CV492, CV493, CV730, CV735, CV740 SV-Series: SV470–SV620 LH-Series: LH640–LH775
