Dosens Stator & Ignition Kit for Kohler KT600 KT610 — 15/20A Complete Replacement with Regulator & Spark Plugs

This Dosens 237878-S kit is a complete replacement stator assembly (15/20 amp) that includes ignition coils, a voltage regulator and spark plugs to restore charging and ignition on many Kohler engines such as KT600 and KT610.

If your small engine has a dead battery, weak spark, or inconsistent electrical output, a worn or damaged stator/regulator package is often the cause. This Dosens aftermarket assembly is designed as a direct-fit replacement for multiple Kohler part numbers and broad model families—covering single- and twin-cylinder commercial and residential engines. The kit brings together the core charging and ignition components so you can replace everything at once and reduce diagnosis time.

What exactly is included and why does that matter?

The kit bundles the stator, two ignition coils, a voltage regulator, and two spark plugs so you get both charging and ignition parts in one purchase. Swapping the whole set prevents repeated disassembly and ensures component compatibility.

• 1 x 15/20 amp stator (cross-replaces Kohler 237878-S and related part numbers)
• 2 x ignition coils matched to the stator outputs
• 1 x voltage regulator to stabilize charging voltage
• 2 x spark plugs to complete the ignition circuit

Which engines and part numbers will this replace or fit?

This Dosens assembly is made to replace many Kohler OEM part numbers and fit across wide engine families: single- and twin-cylinder CV, CH, KT, K, SV, ECH/ECV, and more. It also lists cross-references to earlier OE regulator numbers.

• Cross-replaces: 237878, 237878-S, AM33426 and numerous Kohler numbers listed by OEM
• Compatible families: KT600/KT610/KT620 and 6600–7500 series engines, CV & CH series, K-series, SV series
• Also fits many John Deere LX/STX models and OEM lines such as Command PRO and Confidant

How does installation and performance compare to the original parts?

The Dosens kit is designed for straightforward, bolt-in replacement where the original stator/regulator layout is used. When installed correctly, it restores charging output and ignition timing reliability, reducing electrical faults caused by aged windings or failed regulators.

• Direct-fit connectors and mounting points compatible with listed Kohler models
• Regulator matched to stator output to reduce voltage spikes and battery drain
• Supplies both ignition coils so coil-to-coil mismatch is avoided

What should I check before buying to ensure fitment?

Confirm the OEM part number stamped on your old stator or regulator, and cross-reference your engine model and series. Check connector style and bolt pattern photos to confirm a physical match before ordering.

• Compare your existing part number to the replacements listed in the product details
• Verify engine model (KT600/KT610, CV/CH/K-series, etc.) and model year if available
• Inspect wiring harness plugs and mounting holes against product images

Who this product is for: The Dosens 237878-S kit is aimed at lawn care professionals, equipment technicians, and DIY owners who need a complete electrical rebuild for Kohler-powered mowers, generators, or commercial equipment. It suits anyone who prefers replacing the stator, coils, regulator, and plugs together to save time, avoid compatibility issues, and get machines back in service with fewer repeat repairs.
