I have a Victorinox V7-10 Sub that I've owned for about 15 years. The battery died about 2 years ago and I've just gotten around to replacing it. I've had jewelers replace the battery in the past, as this is the first time I've attempted it myself. It had an energizer 371 battery in it so I purchased a 371 from Batteries +. After replacement, it will not start. Is there an AC somewhere to short against the battery? I see a silver arrow pointing to a round metal piece but that doesn't appear to be it. I appreciate any help.
