5V to Ground shorting (using EM406a GPS)

Hi, 1st post :D

I am using an Arduino Uno R3.

Attempting to connect just the 5v and GND cable from my EM406a GPS module to the 5V and Ground on Arduino...

Shorts out every time.

I thought about trying a different USB cable or USB port( tried port but not cable swap)

I used it in the dev lab at uni the other day when i soldered some wires to the standard EM406a tiny cable and i connected it there and it worked fine from what i remember but now i have it home it just constantly shorts :/

Any help and ideas are appreciated, thank you in advance.

EDIT:

I put it together this morning, it all came on fine..

then i disconnected it to take the gps closer to outside reconnect it and it shorts again ...
