Well I had no denatured alcohol. But I did have an industrial grade glass cleaner, sort of Windex on steroids. The contacts of my Snark are hidden, the battery slides in sideways. So I put some glass cleaner on a q-tip and probed inside where the contacts should be. Before you reprimand me for putting a water and ammonia solution inside my electronic device please recall that the device did not work.
Long story short it began to work! I waited 24 hours because it has worked briefly before, but tonight it is still working. So I think the cleaning has helped it.
Thanks!
Snarks are cheap, I buy them when Elderly has a sale. My goal is to have one on each uke, so that I can grab a case and head out knowing it will have a tuner. This raises the cost of every uke that I buy buy $9-$10, but it saves me looking around for tuners.
And I always turn them off when I'm done. Batteries last about a year on the ukes I play the most. Except that this problem Snark only worked for a week on a new battery, then it got dim and stopped reading. I think the contacts were dirty.
