If you want to check the connections you can have a look to the build manual for the Ultimaker 2 (it's very usefull):

Yes, and click "raw" to get the pdf. Go to page 55 of 69 and in top right, step 16, examine the colors of the 3 wires related - one wire (green in photo) should connect the two fans together to make them "in series".
Smell of smoke is a very bad sign.
Check the voltage at the fan connectors - each fan should be 12V (24V across both fans). If one fan is shorted or open you will see 0V across one fan and 24V across the other.

The back fan is fine, the lights are fine and everything else. Only the side fans wont work.
