Product Overview
A Ski-Doo that loses spark, cuts out after warming up, or has erratic ignition timing may be pointing you toward the CDI—but only after the stator, ignition coil, grounds, tether switch, wiring, and connectors have been tested. If those checks led you here, this module gives you a direct way to replace the failed ignition control.
The CDI controls ignition timing and sends the trigger needed to fire the spark plugs. This module is built around Ski-Doo reference 410918900, making the printed number on the original box the best confirmation before ordering.
Key Features & Performance
- Restores ignition control after a confirmed CDI failure
- Matches Ski-Doo reference 410918900 and common number formats
- Purpose-built for the listed two-stroke snowmobile applications
- Useful when spark disappears intermittently or as the module heats up
Replaces Part Numbers
- 410918900
- 410-9189-00
- 410 9189 00
Common Uses
- Replacing a CDI that has lost its spark output

Frequently Asked Questions
Q: Can a bad CDI cause spark to disappear when the engine is hot? A: Yes. Internal electronic faults can become heat-sensitive, although stator windings, coils, connectors, and grounds can behave the same way.
Q: Does this module need programming? A: No programming is normally associated with this style of CDI. Confirm the original number and follow the Ski-Doo service procedure.
Q: How should fitment be confirmed before ordering? A: Use the compatible list as a starting point, then compare the original reference number, dimensions, connections, mounting details, production date, and equipment or engine serial information.
Q: Is this supplied by the original equipment manufacturer? A: This is a new aftermarket part. The brand and model names identify the applications it is intended to service.
