Flasher Relay CPU Rebuild Service – RX-7 FC
Prevent failure before it starts.
Over time, the flasher relay CPU in the RX-7 FC can develop cracked solder joints and worn-out capacitors that lead to issues like intermittent blinkers, hazard failure, or hyperflashing. While many still function, these units are now 30+ years old — and it's only a matter of time before they fail.
This service is preventative maintenance — done while we’re already in the area, it’s a smart move to extend the life of your electrical system and avoid future headaches.
Service Includes:
Inspection of your flasher relay CPU board
Reflow/resolder of key joints to prevent cracking
Replacement of aging capacitors before they leak or fail
Cleaning of the board and prep for long-term reliability
Final function test before return
Optional: Removal of the OEM hyperflash feature (great if you're running LED bulbs)
Why This Matters:
Prevents sudden flasher/hazard failure
Keeps your signals consistent and OEM reliable
Helps avoid sourcing rare and expensive replacements later
A great add-on if you're already sending in other electronics for service
