Oh, oh this is not good...... With scissor-style crimp tools care needs to be taken to ensure the terminal is crimped as evenly as it can be. Often the seam in the terminal will be cocked slightly so that when the dies come down it winds up vertical.
What's Wrong?
#1 Terminal Not Inserted Correctly
#2 Strip Depth A Bit Too Long
#3 Brazed Terminal Seam Can Split
