Quick Answer
If your battery powered head fails to flash, start by checking the battery charge and connection, then verify the sync mode and trigger. Most issues are simple to fix without tools.
Why Battery Powered Heads Fail to Flash
Battery powered heads are reliable, but they depend on a chain of connections: battery, tube, and trigger. A failure in any link stops the flash. Understanding the common failure points helps you diagnose quickly.
The most frequent causes are low battery, poor contact, or a sync setting mismatch. These are easy to check and fix. Less common are internal component failures that require professional service.
When to Consider a Replacement Battery
If your head works intermittently or only after wiggling the battery, the battery may be worn. Rechargeable batteries lose capacity over time and may not deliver enough power to fire the flash reliably.
For Westcott FJ80 II speedlights, a fresh battery like the Westcott Lithium Polymer FJ80 II can restore consistent performance. This is a simple fix that avoids sending the head for repair.
Diagnosis Steps
- Check Battery Charge: Remove the battery and check its charge level. If low, recharge or replace it. A depleted battery is the most common reason a head won't fire. Keep a spare battery charged for quick swaps.
- Inspect Battery Contacts: Look at the battery and head contacts for dirt or corrosion. Clean gently with a dry cloth. Ensure the battery is seated firmly and locks into place.
- Verify Sync Mode and Trigger: Check that the head is set to the correct sync mode (optical, radio, or cable). Test with the built-in test button. If it fires, the issue is the trigger or its settings.
- Test with a Different Trigger: If the head doesn't fire with the trigger, try another trigger or a sync cable to isolate the problem. If it works, the trigger is faulty.
- Check for Overheating: If the head feels hot, it may have shut down to protect itself. Let it cool for 15-20 minutes and try again. Allow cooling between rapid bursts to prevent overheating.
- Consider Internal Failure: If none of the above works, the flash tube or internal circuitry may be damaged. Stop troubleshooting and contact the manufacturer or a professional repair service. Don't attempt to open the head yourself; it may void the warranty.
