I have one installed but the flashing LED is no longer working on the A-160R monitor, I have renewed the rechargeable batteries but sill no luck
Test the voltage from each side of the LED to earth with a multimeter. If it flashes on and off, the LED itself must be faulty. If it doesn't, you will know the fault lies with the control circuit, which may be as simple as a capacitor and resistor.
