There is no key that was with it but I managed to find a key that works temporarily. I do have battery leads that I found around the place. I have tried connecting it all up. On its own the starter motor runs perfectly, although a little noisy. When attached to the side of the engine as soon as it starts it engages with the motor and just stalls. Doesn't do anything else. If I leave it to long it gets really hot sorry the vid doesn't work
