[sdiy] Amphenol edge card connector sides touch?

[mark verbos]

Definitely not. The power is shut down by the shorting. 
I have had some success putting my wide tweezers into the slot and pushing back and forth.

The pins from the two sides are touching each other when no card is installed, causing the module to short power out. Is this normal for these connectors? Is there a way to stretch it out? Anyone have experience with this?
