Solar panals
Can some one tell me how solar panels work? I have one in a class A that I bought used. Put a new battery in it and dont know how it works. Does a switch need turned on to make it work?

"Proper voltage" on controller cables near battery when disconnected from the battery is 15V-18V. What voltage do you have?
Again, if the installer screwed up big time and installed 24V nominal panel with PWM controller, then even with 15V output you will get very little amps, not enough to charge the battery. Hopefully this isn't the case.
