Kipor KGE2000ti

Have a kge2000ti disassembled and troubleshooting spark. I think i have narrowed to a couple options
1. I need the exact placement of the 2 blue, 1 red and 1 black lead on dc rectifier
2. I wish to bypass the micro on/off switch. Green/yellow wire and red wire from switch. I think red wire can be left disconnected to bypass?

Thought i had disconnected low oil but when cranking low oil light would come on. Added oil. No more oil light.

No spark. Did the stator checks and seems ok.
Any ideas?
I have dld manuals for 2000 and 3000. Wiring diagrams not very good, esp for rectifier.

Any help would be greatly appreciated.
Thanks!
