Piaggio Vespa - No power...literally!

Hi guys, I'm new here. I wonder if anybody can help me with a bit of advice. My son'e ET2 has been laid up for about 3 years. It was working fine when it was put into storage. I dusted it off at the weekend and put a new battery on it. The problem is, none of the elctrics seem to be working. There is power at the ignition, but no lights and no power anywhere else. Any advice would be appreciated. I want to get it running for him now that the "Summer" is coming. TIA

Lights won't work until the engine is running but you should have a brake light.
If not, clean the earth point to the engine and frame

 

Thanks, I now have the engine turning over.! Just need to get some fresh petrol. Does the 2 stroke go in with the petrol on the ET2?

It should have seperate 2t oil tank !
