Inheriting problem

Hi, apologies if has been covered before but i'm needing guidance. I bought a "project" scoot which is a series 3 150 frame, (1963) but has a series 2 engine which i am currently rebuilding. The electrics are my worry. It has a Ducati flywheel and points set up.
1. Does it need a rectifier?
2. What wiring issues am i likely to come across?
Cheers
Pete
