I loath crimp connectors - they were only invented to make assembly "quick & dirty".
I always solder every terminal to the wires.
Excellent tutorial all the same Beaky!
to tell you the truth I do the same on all my crimp connectors. when i re pinned one of the members space invaders pinball machine i soldered every pin after crimping it.
soldering all the crimp connectors that have to do with the G.I is a must because the hand crimper is no where near as good as a crimping machine. if you can pull the wire out of the pin after you have crimped it then it should have been soldered
