TROUBLESHOOTING STROBE LIGHT SYSTEM.
The strobe light flashes as a result of capacitor discharge triggered by a timing pulse. The capacitor is charged to 450 volts D. C. by the power supply, then discharges across the xenon flash tube at intervals of approximately 45 to 50 flashes per minute. The trigger pulse is generated by a solid state timing circuit in the power supply.
When troubleshooting the strobe light system, determined if the trouble is in the flash tube or the power s u p p l y.  Replacement of the flash tube will confirm if the tube is defective. A normally operating power s u pply will emit a 1 to 1.5 kHz audible tone.  If there is no sound emitted, check the system according to the f o llowing instructions.  When troubleshooting the system, utilize the appropriate schematics in Chapter 91. The power supply is accessible through the access panel in the baggage compartment, aft of F.S. 191 .000.
— CAUTION —
WHEN CONNECTING THE POWER SUPPLY INPUT, DO NOT REVERSE CONNECTIONS. REVERSED POLARITY OF THE INPUT VO LTA G E , FOR JUST AN INSTA N T, WILL DESTROY A PROTECTIVE DIODE IN THE POWER SUPPLY, CAUSING IT TO SELF-DESTRUCT FROM O V E RHEATING.  THIS DAMAGE IS SOMETIMES NOT IMMEDIATELY APPARENT, BUT WILL CAUSE FAILURE OF THE SYSTEM IN TIME.
1.  
Ensure the input voltage at the power supply is 14-volts
