How do I reset my multiplex lighting system?
To reset the multiplex lighting system in your Tiffin motorhome (typically Firefly or Spyder Controls system), follow these steps:
🔁 Basic Multiplex Reset Procedure
Turn off all 12V power to the coach:
- Use the battery disconnect switch or
- Pull the 12V house battery fuse/breaker temporarily.
- Wait at least 60 seconds:
- This ensures full power discharge from the control modules.
Restore 12V power:
- Turn the battery disconnect switch back on or reinsert the fuse.
- Check switch panels:
- After reboot, the panels should reinitialize.
- Lights and other functions should now respond normally.
🔧 If That Doesn’t Work
- Look for a specific reset button: Some Spyder/Firefly panels have a hidden or recessed reset button—press with a paperclip.
- Cycle the Master Switch: Some systems reset when toggling the “Master Light” switch 5 times quickly.
- Inspect fuses for the control modules: Blown fuses can disable specific zones.
