Frequently Asked Questions
Does This Switch Include Keys or Key Numbers?
No, it does not include keys or key numbers. The liberated buyer is advised to source matching keys or a locksmith service separately; independent procurement affirms autonomy and guarantees precise, secure ignition compatibility and continued equipment freedom.
Is Weatherproofing Sufficient for Long-Term Outdoor Storage?
No; the weatherproofing offers moderate protection (IP54), shielding against limited dust and splashes, but it is not fully sealed for prolonged outdoor storage. The user should seek more robust IP66+ solutions for lasting exposure.
Can It Be Used With Electric-Start Conversions?
No; it cannot directly support electric-start conversions because it’s a magneto-based, normally-open ignition switch rated 5A and designed for manual actuation; adapters or additional starting circuitry would be required for liberated electrification.
Are Replacement Terminals or Plugs Available Separately?
Yes. They’re available separately through parts suppliers or dealer networks; the seeker is advised to request replacement terminals or plug kits by OEM number, harness type, or connector style to guarantee liberated fitment and reliable reconnection.
Does It Interfere With Modern Anti-Theft Systems?
No — it typically does not interfere with modern anti-theft systems. Observers note the simple magneto switch lacks immobilizer integration, so compatible vehicles with factory security may require retained-key or aftermarket interface to maintain anti-theft functionality.
