Troubleshooting Procedure: The following information is to provide guidelines for troubleshooting the LED

Light Models listed on page 1.

Note: A circuit feature of the Parmetheus Plus is multiple parallel paths of LEDs and fixed current sources.

For this reason, a group of 3 or 6 LEDs may not be illuminated, while the remainder of the LEDs may be

operating at full intensity. This creates a situation where the light may be producing adequate light to perform

its intended function, but it should still be replaced.

In the case of no light output:

1. For a new installation, check the polarity of the wire connections. Check that the appropriate part has

been selected for the aircraft.

2. Check for the correct voltage at the light (+14V / 28V) terminal. Check for ground at the (GND) terminal.

3. Check the connections at the (+14V / 28V) and (GND) terminals.

4. Perform a bench check and replace if a failure is confirmed.

Refer to the aircraft manual for additional information.
