recently that had a poor contact with the 'twisty' to PCB ground path. It was dead. Never saw this before. A little solder on the pads near one of the 'twisty' solved it.

Also I think the capacitor is tantalum.

On further examination, the entire ground shield appears to have good contact with the twistees. I confirmed this with reading voltage from positive terminal to ground shield in several places. It reads the exact value of the battery voltage.
