Pulled apart my NOCO genius 3500 charger last night. It died a month or so ago and I finally found the stupid tri-bit that was required to get in. protip: if there are tri-tip screws on a product it means they don’t want you in there to see their work.
Looks like a cap melted down and took some other components with it. So much for protection. Granted I’m not at all surprised, AvE warned me of the crustiness.
