Narrative:

I was assigned to work on aircraft to troubleshoot deferrals [deferral no. 1] and [deferral no. 2] per fim 27-62-01. I attempted the operational test per amm 27-62-00-715-002. This test failed. I then performed the B.I.T.east. Of the sac. This test has 2 levels one being the auto test; the other being the rig test. The rig test failed. At that point I re-deactivated the auto spoiler system as it was when the aircraft arrived. I was not aware of mib 6-27-15-08 which explains the rig test bite of the sac. Consequently the spoiler handle was restricted the spoiler handle movement to 50% travel. I had tested the spoiler handle operation prior to troubleshooting but neglected to do so after troubleshooting.
