With USB plugged in and no Load or Battery hooked up... I get 1.3V when I measure from the positive terminal of DCIN (with Ground wire of Multimeter touching the Negative of DCIN).
I also took measurements off ....
the Load terminal = 0V
the Batt terminal= 0V
ok. here is where it gets interesting/telling
Before I did this test, I had the charger hooked up the the solar supply and Lipo... and as I stated earlier, this does cause the PWR Good LED to light up (if enough SUN)
So I think the measurement above is just power left over in the Cap, because I can measure the power at the DCIN WITHOUT any power source connected (no Solar and no USB) and I get the same VDC measurement as when I have the USB connected.
Hopefully I have described this clearly enough ... Let me know if further explanation or testing is needed. I am thinking the board has a problem... maybe the badly aligned DONE led is a bigger problem than I originally thought.
HEre are some pictures.
Thanks for the help. I am eager to get this sorted and my remote weather station is ready to go into the Wild! finally
