Monitor-shmonitor... It will do a lot of good when you don't use it. Or - when there is not enough charging for given loads.
You have a tiny solar. Get a 12V fan. Convert lights to LED if the factory haven't done so. Look at the battery voltage - on controller display - in the morning and later from time to time, until you get the idea of what is going on.
Did I mention to look at the display? :)... Broken controller input wire - or output, the OP has gone cryptic again. It would read zero amps on display and battery voltage would not be rising. Your solar was not working, you would've known this yesterday if you had checked the display.
For pure academic thrill, if you really must know current drawn by each and any of your devices, turn them On, one by one, when sun is shining and battery is in Float. Pump not running - X amps on display, turn the pump on - Y amps, subtract one from another. Elementary school math, 2nd grade (or is it 1st grade?). If this is too difficult, then look at the voltage in the morning and correct your energy use accordingly.
You added 2 more 6V - now you can (and will) conserve energy less than before, while still having no idea how your charging is going. Happy camping...
