problem with 12vdc controller , says charging but nothing seems to be happening

[turbo1600]

how come my solar panel out put is 30vdc in full sun , without it connected up to the controller , but when i connect it up to the controller and measure the voltage at screw terminals where panel feed goes in it reads 12.6 vdc . lead acid battery is connected . it was working perfect with the same type controller , but the battery symbol had no lines in it.. ( charging state ?) so i replaced it now this is happening.

My first question is what is the charge level of the battery? If it is more than 90% the charger may not be doing anything.

Second question. Did you hook up the battery to the charger first and then the panel to the charger? Doing the hookup in a different order may cause the charger not to do anything.

Finale question. What is the Amp hour rating of the battery and how many amps can the panel produce?
