ammeter?

I'm trying to wrap up everything on the car so I can fire it up.
I keep blowing the 20 amp fuse in socket 4 of the fuse block, as soon as i hook up the battery it sparks and blows the fuse. My father-in-law and i removed the gauge cluster, and upon doing this it stopped. Held the connectors for the ammeter together and the spark was gone. Placed them back on the ammeter, it sparked and blew the fuse. Would it cause any problems to remove the connectors and splice the wires together since the ammeter only measures current?
