On Z-Spar masts the conduit runs up the aft inner corners, at least they do on mine a Z601, and the wiring
for the running light, radar
and spreader lights come out the front. Not very smart I think. I guess they figured the halyards would stay to the sides since the exit plates are there, and the wires could pass thru the center safely.
I'm sure not all masts are this way but it's good to check.
Anyway, after I got my wires down the center between the halyards I cut a notch in a piece of conduit for the back end then ran it over the wires to the back side resting it on top of the mast conduit. I cut the front end so there were a couple ears going up & down that went flush in the spinnaker
track grove, then sealed it in place with 3M -101 sealer. Then spliced the wires to the light and remounted it. At least now if the halyards go slack they can't rub the wires and if they hit the conduit the ears hold it in place.
I must have went up and down the mast 20-30 times and it turned into an all day project
. But no big deal. You should see the crap I have to do at work!
