Quoted from barakandl:Atari games used a spade connector on coil lugs. Like a spade connector WMS used on the bridges in system 3-7 games. Found them to cause some problems in a middle earth and ended up soldering some in place.
I have NEVER been able to remove a spade connector from the bridges on a WMS 3-11 when I go to add the inline fuses. I'm guessing its just the time/heat that seizes them on there, but sometimes I swear they were welded on lol
