High Voltage #1

4.3.1.1 Observe high voltage LED (D14) on the high voltage rectifier PCB
#2, to determine if it is available. If the LED is dim or out
completely, then check the high voltage capacitor bank (C103 -
C109 daymode, C102 nightmode) for a short. If no capacitor is
found to be shorted, check the resonant cap (C101) for a short. If
the resonant cap is okay, replace PCB #2. If the LED is at full
illumination, go to the next step.
4.3.1.2 Check the status of trigger LED6. If LED is off, check fuse F2. If
blown, replace with exact type of fuse. If the fuse blows again,
replace PCB #1. Check transformer T1. Replace as necessary. If
LED is okay, go to the next step.
4.3.1.3 If steps 4.3.1.1 and 4.3.1.2 check out okay, re-lamp the
STLDBEACON.
