Reg/rec wiring question...

Pick up a new reg for my Kat, can I wire the 3 stator wires to the reg, then wire reg direct to the battery with a 30a inline fuse?

 

At the minute one stator wire goes into the loom, I've read that it goes into the headlight circuit for some reason O.o

Correct...

 

Spot on, cheers, I don't have to power the original headlight circuit that the stator wire goes to,  just leave it disconnected?

correct the stator wire isn't for powering the lights

its a weird electical cul de sac that suzuki came up with in the 70's and 80's not realising i think how it would work in th long term. the wiring goes to the light switch, but doesnt power the lights. the alternator charges the battery using two of its three phases sent through the reg rec, and th third phase is also connected to the reg rec but via this loop of cable through the light switch. thee idea supposedly being that whn you put the light on and needed more power, the third phase of the alternator would then come in to play giving the battery all three phases worth of output. im assuming that the katana came about after the electrical design guy was sliced up ceremonially with one to punish him for this fuck up....

You can, but I would rather rely on the 15A fuse in the stock wiring. 

Bypass the switched 3rd phase loop like so:
