Solar panel not charging battery
Throw out (put it back on the shelf) that charge controller, there isn't enough information about it to make sense of.

Just get a Schottky diode (1A will do. Find one on eBay or whatever, look for 'solar panel blocking diode') and put it between the solar panel and the battery. You will at least get some charging from the panel. If you pop out every evening and disconnect the panel from the battery before dark, you could even skip the diode.

You should measure the current from the panel to the battery. But this might be too likely to destroy your meter or at least blow the fuse in it, as it is nearly 100% certain you will put the current meter probes across the battery. 

A quicker way is to see if the battery voltage goes up when you connect the panel to it. First get rid of 'surface charge' by discharging the battery a bit, say, with a light bulb or something. Remove the lightbulb or whatever. Then, measure the voltage (across the battery) before you connect the panel, then right after (with the panel in full sun, of course). 

If you just leave the panel connected, with no blocking diode, when the panel is in the dark current will flow back into the panel from the battery, and, depending, may discharge the battery more than it is charged in the day. That is why I said 'if you pop out every evening and disconnect ...'.

Once you get all this sorted out, have worked out some way to measure current, know what condition your battery is in, and have your system doing some work, try the charge controller again. Probably it works just fine, and there is some mis-understanding.
