My O’Day 22 (‘78 MH rig) has one mess of an electrical system. One improvement is to replace the big knot of twisted wires that currently serves as the common negative with a proper negative bus bar. The problem is where to mount it. I’d like to keep the original panel location (starboard side bulkhead, just inside the companionway) but the only way I can think of to install the negative bus near the panel would require cutting open additional access. The current common negative mess is just shoved deeply into the approx. 1” gap between the inner and outer fiberglass skins. Would it be better to cut open more access or to maybe run all the negatives elsewhere where I already have access? (e.g. near the battery in the starboard lazarette just *outside* the companionway). How was the original wiring accomplished/serviced in such a tight space? Tangential thoughts are welcome as well.
