Your small solar panel may not keep up with any loads, but another possibility is that your battery has a dry cell... depending on the type you could refill with distilled water, and put a real charger on it for a couple of days.
Don't think you can rely solely on a small solar panel to maintain a charge once you start using amps....
Or, as you say, perhaps there's a broken connection somewhere.
