Photogenic Powerlight

PL 06A does not work when the yongnuo RF 602 receiver is plugged in to the sync cord plug in the back. Even the test button on the powerlight does not work. even when using test mode from the transmitter it doesn't fire the powerlight. The sync cord itself works perfectly. My wireless receiver needed a plug so I bought a metal one. The optical slave works good on it also, just the wireless trigger/receiver doesn't work.

Guess it is my wireless stuff that needs replaced???

I'm using a Canon 50D

That would be my guess.....
If all other connections work via the sync except your wireless, I'm willing to bet that is probably the issue.

Would the metal plug adapter have any role in it? I'll just get a new trigger and see.

Yes, very possible, sometimes it is a bad cord..... try a different cord if you can. Also, ask a fellow photographer that you know who has a set of wireless triggers to borrow theirs and see if it fires your unit. If it does, then at least you now know it's not the flash unit. Now your last resort is to get another cord to see if it really is just a bad cord or your wireless unit.

There have been instances where reversed polarity in the plug has caused the non-firing situation.
It may be worth trying to reverse polarity. Not too hard, and there may be a relatively easy way to do it without having to rebuild the jack.

Ok. The only photographer around that does wireless that I know of does the optical wireless slave built in the unit and that works just fine. Most of the pros around here are very arrogant and snobby and I'd never ask them for help. Funny that the wireless function works fine on my speedlights with the same transmitter and receiver. I guess it could be the metal plug instead of a plug with a rubber or plastic end. I just ordered another transmitter so we'll see in about 10 days, it will take that long to get it.
