I have the same probe, but I haven’t tested it yet. Based on the documentation I read, this probe switches on the negative (–) instead of the positive (+). So this is probably an electrical issue, and you need to change the wiring.

I recently got a new probe, and discovered that if I wired it *correctly* it did not work.  I had to wire it backwards, because the small current used to make the light go on when it "hit" was also enough to drive the 7i76E pin, so the probe was always "not hit".  So even if you follow the directions, sometimes it takes more debugging :-P
Always check the voltage at the pin!
