Rec No.	Date	Loc From	Title	Loc To	Notes
6202	2023-03-02	Lab none	Tested	Disposed none	This charge controller hasn't been showing solar amps. I took it apart and cleaned out a bunch or large dead ants. I found two diodes and one capacitor that looked a little fouled but not obviously broken. I'm not sure I have the tools/skills to do any more. I cleaned it up, put it back together and tested it. Now the screen shows nonsense - different on each power cycle. I think it's a goner. Put it in the e-waste box.
