I had to do a fair amount of rewiring on Selene. I started with the wiring diagrams in the manuals:
http://www.pearson323.com/documents/323manual1978.pdf; They were useful in providing a basic orientation to the system. However, there were so many changes - although mainly additive - I found it a useful starting point but no more.
I was replacing a panel, and so ended up tracing and replacing (as necessary) any new circuits one circuit at a time.
A few learnings (apologies if you are a pro!):
* Buy a good crimper; I had to replace MANY badly crimped connections. I bought a double and single crimper, and don't regret it at all. Poorly crimped connectors was the biggest source of failure in my electrical system.
* The heat-shrink labels (numbered/letters) are very useful.
* I really like the spiral-wrap plastic cable organisers you can get from any hardware store.
- it is great for bunching wires together, and because of the spiral wrap it does not trap moisture.
* Blue Sea stuff is expensive, but the really nice - I love their backlit labels!
* My favorite projects site
