Just thought I would throw this out to the smarter people before I gave Whelen a call tomorrow. (I did a search but did not find the info I was looking for)
Equip:
Whelen A490, T-DF-14/28 strobe power supply
Aeroflash 073-0540G (Nav/Strobe/Pos light)
Problem: Right strobe quit working. My power supply date of manufacture is Oct 02' so I know it is old.
(Left strobe w/ individual pwr supply works fine.)
I have verified 12V going into power supply and a good ground, but did not complete Whelen troubleshooting guide as I just found it on VAF tonight after I left the hangar.
My question is, if the power supply were good and the flash tube the problem, would you be able to hear the power supply working? Meaning, when everything is functioning properly, you can hear the power supply hum, buzz and snap with the strobes.
Just wondering if the power supply could be good and the flash tube bad. If this were the case, would the bad tube cause the power supply to be quiet and appear not to be on?
Thanks,
Dan
