Temp sensor on solar controller.
The temp sensor on my Windy Nation P30L solar charge controller isn't working. Worked last fall when I unhooked the battery's for winter storage but when I hooked everything back up there's no readout for the temp. The wire I can see looks good and the connections at both ends look just fine.
I don't know how the temp sensor works, can someone explain how a wire hooked to the negative battery post tells the controller what the temp is? Also can I go to cutting the terminal end off the wire and put on another one or if my wire is cut can I fix the cut with a butt connector?
I'm thinking that if I have to pull the wire to see if its cut or not I will need to remove the battery ring terminal as its not going fit through the area its run in anymore.
