Frequently Asked Questions

What does self-resetting mean?

The breaker automatically trips to cut power when it detects an electrical fault, then resets without needing a manual switch — no replacement needed after a trip.

Will this fit my Sportster or Softail?

This part is designed for FL, FX, and XL models from 1970-present. Check your bike's wiring schematic or contact tech support to confirm fitment on other models.

Is this a direct replacement for the factory breaker?

Yes — it's designed as a direct OEM replacement. Disconnect the battery, unbolt the old breaker, and bolt in the new one in the same location.

What happens if the breaker keeps tripping?

Repeated trips indicate an electrical fault in the charging system or wiring. Have your electrical system diagnosed before riding — don't just replace the breaker.
