Let the fun begin !!! ???

i decided to test the coil with a power up so i used a safe block , hooked up the brown and blue to 230 vac i then joined black and yellow together and red and orange together on the secondary and put them in a terminal connector . when i engaged the safe block the coil hummed for about a second and then stopped. i checked the fuse in the safe block ( 13 amp ) and it was blown so i tried again and the same thing happened. i metered the connector and obviously got no reading . am i correct in thinking that i should not have blown the fuse and should have 50v ac across the terminals?
