Thanks to everyone who responded to my original
post....unfortunately I have yet to find the problem. I'll try
to make my explanation clearer than last time:
Blade is wired up and connected to a test box. Both lights on
the box are dark. I press the tip, and both the epee
and foil lights go on. I take out the weight spring and try
a few different tips, but the problem remains. I remove
grip, socket and guard and check the insulation on the wires
and there is no exposed wire. I peel the wires away from
the blade about a third of the way down, and find no
Now, with the wires partially peeled away from the blade, I
reconnect the them to a socket not in contact with the
blade. Under these circumstances, it works properly. Whenever
I touch the metal of the socket to the blade, however, the foil
light goes on as well (with tip depressed). With different
sockets and different tips, the same thing happens.
If I only plug the two close-together prongs of the body cord
into the socket, the blade works properly. When the third
prong makes contact with the third hole of the socket, the
weapon fails (both lights of the test box goes on with tip
I'm confused! If there is exposed wire touching the blades
somewhere, shouldn't the foil light go on even when the tip is
not depressed? The strange difference between when the socket
touches the blade and when it doesn't seems to suggest that
exposed wire is not the problem. The body cord and test box
work fine with other weapons, so that's not the problem.
Things go wrong with no pressure spring and different tips, so
contact with the barrell doesn't seem to be problem either.
Same problem occurs with each socket I try.
What's left to go wrong?
