This video provides a detailed step-by-step guide on how to troubleshoot the DRY and WET relays on the ButterflyMX 2-Door Controller using a multimeter.
You’ll learn:

• The difference between DRY and WET relays
• How to isolate the relays for accurate testing
• How to use continuity, resistance, and voltage modes to verify relay functionality
• What multimeter readings to expect when triggering the system
• How to confirm proper relay operation or identify potential faults

This guide is ideal for technicians or installers who need to verify relay performance during setup or troubleshooting. If results differ from the expected values, capturing a photo or short video is recommended for support purposes.
