Once again i'm writing English couse i'm Norwegian

I am making my own Electrical grid on my Gilera Rcr 04 because, well, most off us know that the original is crap!
I was using av Derbi Drd Pro 10 engine with El-Start, so therefor I have a Derbi 2010 electrical grid now with the 5 pins Voltage Regulator.
I have the gear ++, but i need to know how the 12v battery is charged!
I Also have the Koso 12-30 Ac/dc to 12-15 DC regulator.
Can I charge the battery like this?
Ignition --> Koso Regulator --> Battery
Ignition --> Lights
Battery --> Lock --> all the electrikal stuff! (Koso Rx2N speed+)
Would appreciate some help
