SON y junction box grounding question
Son edlux II (k607) front light
b+m Line small plus rear tail light
SON delux (k687) hub
Bought the y junction and just getting ready to wire this up.
Im going to cut the 2.8m male spades off the rear light and solder the rear light twin leads to a run of (bm) coax up to the front where it will plug into the y junction box.
My question is: Does this return leg need to be grounded to the frame (its steel) or to the front light mount/brake mount?
Or is the circuit grounded at the front hub through the return leg?
