I am having a similar problem with my 2009 robot SG that it is not taking a charge , I had to pull out the tuning keys and manually tune it to play it for a while plugged into an old tube amp to see if it would help it take a charge , don't know if it helped yet . Before this I have attempted numerous approximately 90 minute charging sessions with no success . When the tuning system was working properly I have played unplugged many times (about 50% of thev time) to figure out songs , especially going to open G for figuring out old Rolling Stones songs and reverting back to standard tuning , could this have damaged the battery ? Until lately , I only had to charge it up once when I first bought the guitar new in early 2010 . Can my battery be malfunctioning and not accepting a charge now possibly . I am a former journeyman electrician and electronics technician with a bachelors in electrical technology , so I should be able to replace a battery if needed . I have never opened the access panel yet . I am trying another charge session now with a slow single green flash on the MCK and severall multi-colored and now yellow rapid flashing on the charging unit with a less than one foot cable between the charging unit and the guitar . We will see if this time it takes a charge . Any input will greatly be appreciated .
Thanks much , Rock On !
