Titus213 Cream of the Crop  More info | Oct 20, 2007 01:23 | #2 Does the flash fit securely into the flash cord? I would expect the flash cord hot shoe is susceptible to the same problems the camera hot shoe has, the rails get bent up a bit allowing the flash to move just a bit in the hot shoe breaking the connection.

The "center" connection (the larger contact on the end that the flash connects to) definitely has a diode in between the two ends of the cord. The four smaller connections are just straight-through connections. Skip Douglas

This caution is especially important for gold-plated contacts. Skip Douglas

Instead, use a little isopropyl alcohol on a lint-free cloth to clean the contacts. If that is not enough cleaning power, get and use (gently) a white drafting eraser which is MUCH softer than the standard pencil erasers. Thanks for the info...I had always heard to use an eraser on contacts but I'll have to be more carefull on which eraser I use.
