Hello I recently bought a gunfighter stick with 200mm extension and KG12 Grip, it worked great for a month or so but now the buttons stop working, I thought at first the connections the between grip-extension-base but they seem good
Then a couple of times it worked again when I flashed the firmware, but I think this was a red herring, just coincidence.

Anyway, I tried again today to see if there was any problem with the contacts, and with a eyeglass they still look fine, so I thought I would check the continuity and resistance from one end of the extension to the other and found that 2 pins measured 4 Ohms but third pin measured 1.9 Ohms, are they acceptable values?.

Clean up the 3 contact pads on both one end of extension and base stem with a cloth and a bit of alcohol. If it still doesn't work when installed back try removing the extension and see if only stick on the base works.

Already done these things, stick works without extension

I have found the fault and fixed it myself, the high resistance reading on one of the contacts was a big clue so I disassembled the extension and found that one of the pins in the connector plug had not been inserted correctly (see below)
