So did mine. Charged with a common electronic tender, came to a steady 13.35v meaning about 90% capacity. Started a K12 very easily several times. Hope she might come back from a possible dead situation and be ready for a few years service. In the growing process of migration to the new technology, might serve someone the way I adapted mine. In this photo is missing another plus. On the front pannel was fitted a "loudspeaker box pressure connector" for GPS and other fused low amp's aplications. There's plenty of room. Colebatch, Your rides and reports are most appreciated. A great source of information, entertainment and dream feeding, they are. Many thanks to you and the gang.
