[ElectricMotorcycles] Freccia repairs

I dismantled the dead etek, which isn't too hard, but it does help if you have a press. It had totally shed about a dozen connections and some of these had gone AWOL on the trip home. I've made new ones and re-soldered nearly all the connections, but I have to fix my 1960's 'instant heat'
