I have very basic knowledge of electronic components and tinker in an attempt to learn more.
I have a simple Solar Panel Light kit. 18V 10W Solar input, 12V7Ah Battery output to a couple of LED lights, USB output for charging.
I tested the battery voltage as 12V
When connecting the battery to the board I test 12V where it should be, I tested all diodes and I picked up a possible issue with one.
When a test with a multimeter in diode mode, negative probe on the striped side of the diode and positive on the blank side I get a reading of 165,
if I reverse the probes I get a reading of 913, where it should be none. I removed the diode from the board and tested it and the diode test correctly.
When placing the probes on the pads on the board in the correct layout I get a reading of 781 and reversing the probes 913.
I am not sure what to make of the data I am getting.
All diode testing was done with power disconnected.
Please, some advise would be highly appreciated.
