BEST WARRANTY IN THE INDUSTRY!
NOTE: HewTech Electronics LLC cannot warranty the individual coils used in the ROTAX FIREPLUG CDI. We purchase these parts from PARTS-UNLIMITED, and test them prior to installation. We have absolutely no control over their quality or workmanship to warranty them. PARTS-UNLIMITED does not offer ANY warranty on electrical parts, therefore HewTech Electronics LLC cannot extend our warranty to cover the external coils. If a coil is found to have failed, HewTech Electronics LLC will warranty the labor at no cost to replace a coil, however cost of the coil & shipping is the responsibility of the CDI owner, and not HewTech Electronics LLC.

Uses original Factory 3-wire AND any standard 2-wire kill-switch!

After a 5 year hiatus, HewTech Electronics is now offering A POLARFIRE Replacement FIREPLUG CDI for the 73~78 Ski-Doo & Moto-Ski’s ignitions (Replaces CDI 1-217-280-017 & 1-217-280-044).

We built a prototype that included all the FIREPLUG CDI improvements we learned over the years and sent it out for dyno-testing and evaluation. Our efforts paid off. We now have a PolarFire replacement FIREPLUG CDI that follows the OEM timing exactly. We also match the OEM wiring connectors & mounting holes, so no timing adjustment, no wiring & no holes to drill. Just bolt on & GO with FIREPLUG reliability and performance!

TECHNICAL PROBLEMS
STILL NO-SPARK?

Verify that the chassis to engine (bonding) wire is connected & in good condition. Without this wire connection, the FIREPLUG CDI may not spark or operate correctly.

NOTE: The stock CDI may operate without this bonding wire, since it uses the aluminum case as a common ground. The FIREPLUG CDI case is isolated and no current passes through it, therefore the wire to connect the Chassis to Engine is necessary.

The Brown wire (our Black wire) from the connector grounds to the engine crankcase. This wire often times breaks or corrodes over time. Verify your brown-wire does connect to engine ground coming from your engine, through the harness to the CDI.

Disconnect kill-switch harness, often times the kill switch & key-switch fail & short out the CDI box.

Verify Stator & Trigger resistance: ~315 ohm Stator (RED to Brown) & 55~60-ohm triggers (striped wires).
