| Strange epee prob...
Danged if I can figure this one.
1) New epee....only seen a week or so of use. German parts, smooth action. Rock solid on the test box (no wavering, 1 ohm resistance when tip depressed)
2) Scoring box is a Favero. Fencer plugs in...pushes tip...no light. Switches weapon, good light.
Body cord and floor cord are fine...no problems when he's using the backup weapon...original weapon DOES work on other strips.....
Help? |

| you said "Body cord and floor cord are fine", but how about the reel? i have seen where the reel does not work when the fencer is in a certain spot...if the fencer was so far away from the reel, the weapon worked, if he got closer to the reel, the weapon did not work.
i have also seen where i grounded out a and b lines on a bodycord and the machine registered, plug the weapon into the body cord, did not work. got three other weapons that did the samething. a few minutes later, someone informed us the reel was not working. got a new reel and problem was gone. | |

| The thing is, that weapon only failed to fire the light on that one strip. On other strips with the same body cord (he's only got one), no problem. He switched weapons on the original strip and it was working fine.
Somehow it looks like that specific weapon only on that specific box....an no one else reported any problems on that strip, so I don't think it's in the club gear...perplexing... | |

| Poltergists.....or maybe a weapon wire/reel wire incompatability? too much resistance?

| there seems to be oly three variables that might causing the problem, the machine, floor cable, and reel. by any chance, does the weapon work on the other side of the strip? | |

| Argh....I was in the middle of a massive epee wiring job for one of the local school teams and didn't even try that. I'll mention it to him the next time I see him. | |

| Can't believe nobody's mentioned this yet...
You checked A-B connection/resistance. Did you check for a short to ground (C)? If either the A or B line shorts to the C line, the weapon will pass an ohmmeter test, but will not register on any machine. |

It works great in practice. Before every tournament it checks out Ok. I get on the strip and it fails every time.
Afterwards, I fix whatever problem was wrong, and the whole thing starts over again. Can Epees be cursed? | |

With SG and Eigertek boxes, for example, a short of A or B to C does not prevent the weapon from registering (remember that with modern microprocessor boxes C is not really ground, just another input that is being sampled by the ADC in the box). What happens with such boxes though, is that if you have A & B both being shorted to C (say, due to the insulation of both wire getting pinched between the grip and the guard), you'll get a false touch registering-- something to keep in mind for on-strip troubleshooting.

-Dave | THANK YOU DAVE!!! I had thought it MIGHT be a box issue, but had no experiecne to base it on. I'll check it next time I see him! | |

-Dave | Thank you, that actually helps me with an epee problem I had. (First, it was grounding, then, it was registering false touches, and I wasn't sure what was going on.) (It was a loose barrel, I found out...) | |

I firmly believe that there are gremlins that crawl into my bag overnight and loosen tip screws, lengthen contact springs, unscrew barrels, etc.. Maybe I need to start rubbing my weapons with chicken bones or something...  | |

OTOH, if they sign up with the Teamsters, things could get.....messy. | |
