Anybody pulled a new wire through a standing mast?
Went to replace the anchor light and found roughly half of normal battery voltage at the top then found a full 12.7V in the positive bilge wire at the bottom of the mast. By jumping to the mast at top & bottom I verified the issue is with the positive and not a bad ground and found the incandescent fore-deck light is dim, so it probably has the same issue.
Found some other wire connections in the bilge were green and corroded and the two light wires (+ & - ) at the top of the mast are a different set of colors than at the bilge. Bottom line is that it appears SOMEWHERE there is at least one corroded splice between the bottom and top. I've pushed pieces of tubing sleeve over the bottom of the wire as far as possible and only gotten maybe a few feet up from the bilge so any splices are above that.
It appears to me that the most likely place for splices would be just above the tube in the mast step. This is where the wires pass through the deck and that can only be reached by dropping the mast, plus it's the most likely area for wires to be damaged when the mast last came down. That sure isn't happening to simply replace one or two sets of light wires.
So the questions for those of you who've replaced wires or at least tried:
Are the wire sets tie-wrapped to anything inside the mast to prevent pulling new wires through?
Pulling the wire set downward through the mast step would probably cause the splices (+ and - ) to hang up on the tube in the step. Any thoughts on whether it'd be possible to solder a replacement wire set at the bottom then pull the set up to the top?
Other ideas?
Thanks in advance,
