An MD80's right thrust reverser was inoperative, but only the annunciator light was placarded by maintenance. During attempted use of the inoperative thrust reverser, the flight crew experienced increasing forward thrust and yaw.

Narrative:
Upon landing, our right thrust reverser did not deploy which caused some adverse yaw during deceleration. Not only did the thrust reverser fail to deploy, but as the captain continued to activate the reverser, we seemed to have increased forward thrust. The left thrust reverser functioned normally. Come to find out that maintenance was supposed to secure the right thrust reverser lever in association with the inoperative annunciator light that was placarded inoperative. In the future, I will thoroughly research and read all MEL items that are placarded, whether or not the captain inquires about this, even if it's only a light which is placarded.

Title: AN MD80'S R THRUST REVERSER WAS INOP, BUT ONLY THE ANNUNCIATOR LIGHT WAS PLACARDED BY MAINT. DURING ATTEMPTED USE OF THE INOP THRUST REVERSER, THE FLC EXPERIENCED INCREASING FORWARD THRUST AND YAW.
Narrative: UPON LNDG, OUR R THRUST REVERSER DID NOT DEPLOY WHICH CAUSED SOME ADVERSE YAW DURING DECELERATION. NOT ONLY DID THE THRUST REVERSER FAIL TO DEPLOY, BUT AS THE CAPT CONTINUED TO ACTIVATE THE REVERSER, WE SEEMED TO HAVE INCREASED FORWARD THRUST. THE L THRUST REVERSER FUNCTIONED NORMALLY. COME TO FIND OUT THAT MAINT WAS SUPPOSED TO SECURE THE R THRUST REVERSER LEVER IN ASSOCIATION WITH THE INOP ANNUNCIATOR LIGHT THAT WAS PLACARDED INOP. IN THE FUTURE, I WILL THOROUGHLY RESEARCH AND READ ALL MEL ITEMS THAT ARE PLACARDED, WHETHER OR NOT THE CAPT INQUIRES ABOUT THIS, EVEN IF IT'S ONLY A LIGHT WHICH IS PLACARDED.
