GOIMGN Ignition Coil & Regulator Kit for Kohler 8–25 HP Engines — 2 Coils (24-584-01-S/24-584-45-S) + Regulator & Spark Plugs

A complete ignition coil and voltage regulator kit containing two replacement coils (24-584-01-S / 24-584-45-S), a regulator/rectifier and replacement spark plugs designed to fit a wide range of Kohler 8–25 HP small engines.

This GOIMGN kit groups the ignition coils, a voltage regulator/rectifier and spark plug extras so you can restore reliable spark and stable charging on many Kohler CH, CV and SV series engines. It replaces several OEM part numbers and is meant for routine maintenance, repairs after coil or charging faults, or to upgrade worn ignition components. The components are built from corrosion-resistant materials and specified to provide steady output, helping engines start consistently and maintain electrical system stability.

Will these parts fit my Kohler CH, CV or SV series engine?

The kit is compatible with many Kohler engines in the 8–25 HP range. It covers common OEM numbers and fits CH series (CH18, CH620, CH640, CH670, CH680, CH730), CV series (CV17, CV18, CV20, CV22, CV23, CV624, CV675, CV730) and SV series (SV710, SV720, SV725, SV730) models listed by Kohler.

• Replaces ignition coil part numbers including 24-584-01-S and 24-584-45-S.
• Voltage regulator replaces 41-403-09, 41-403-10-S and 25-403-03-S equivalents.
• Compatible across many 8–25 HP Kohler small engines used in mowers and equipment.

How will this kit affect engine starting and electrical stability?

Fresh ignition coils and a functioning regulator restore strong spark and maintain correct charging voltage. The coils deliver the high-voltage pulse required for ignition while the regulator/rectifier ensures the battery and electrical system receive a stable output.

• Coils designed to produce consistent spark across operating conditions.
• Regulator maintains approximately 14.5±0.5V to protect the charging circuit.
• Includes spark plugs to complete basic ignition system replacement for faster troubleshooting.

What are the durability and safety features of the components?

GOIMGN uses materials selected to resist heat and corrosion common in small engine environments. The regulator is built to limit over-voltage and deliver predictable output, reducing electrical stress on battery and wiring.

• Coils moulded with high-quality insulation to reduce moisture ingress.
• Regulator/rectifier protects against over-voltage and over-temperature conditions.
• Included spark plugs are new to help ensure clean combustion and reliable starts.

How simple is the swap and what should I check before installing?

Replacing coils and the regulator is a straightforward mechanical task for routine small-engine maintenance if you have basic tools. Confirm model compatibility, disconnect the battery, note wire routing, and follow OEM torque and clearance specs during installation.

• Check engine model and OEM part cross-reference before purchase.
• Disconnect battery and remove ignition wiring carefully; mark connections.
• After install, verify charging voltage and spark timing per service manual.

Who is this for: This GOIMGN kit is aimed at do-it-yourselfers, small-engine mechanics and fleet technicians who maintain lawn tractors, commercial mowers, generators or other equipment powered by Kohler CH/CV/SV engines. It’s useful when coils show weak spark, the charging system runs hot, or when you want a single-purchase solution to refresh the ignition and regulator components and return equipment to dependable operation.
