If the clock is working properly, it will work fine on a 9 volt battery (it will probably be killed by reverse polarity, so be careful!). I have a spare mechanism that I repaired earlier, and I just tried this.
Are the gears reasonably clean? This thing has very, very little power to work with. If not, I might try a little silicone spray and a Q-tip on them. DO NOT USE OIL OF ANY KIND, period.
Are all the gears straight up and down? I had a mechanism that I could not repair with a broken pin on the end of one of the gear shafts.
There is a - sign on the back of the PCB where the - stripe on the capacitor should line up at. It's small and you might need a magnifying glass to see it. Note that this is different than (at least US) convention, where + is marked.
Did they give you TWO of each? it isn't unheard of for RS stuff to be DOA. I'd try again, being careful not to overheat the board and lift the traces. This is not a modern board and it will not tolerate a lot of heat.
