Olympus 35 EC2

Hello All,
I have picked up an Olympus 35 Ec-2 and have a question. I am having a problem with the batteries. I have done the tinfoil trick and it seemed to work but then found an adapter for sale on eBay. Now i can't seem to get the camera to fire at all. Has anyone else used this adapter

I am lost and any help would be appreciated.

I would check the resistance on the camera, clean contacts, it worked before. Could be that you shorted it when using foil.

Sorry, but how does one check the resistance? And thanks
