Agreed! I'd forgotten about suggesting that. There's an issue that occurs when batteries are left connected during long term storage. It's called black wire disease. Basically the black or negative wire corrodes badly and spreads to everything the battery is connected to. The switch being the first victim. The corrosion will cause your twitchiness.
