I re-wired my 1972 Yorktown Slip a few years ago. I referenced several books to help me including the 12 v Bible. You have already received some good
advice but I would add the following.
-Figure out your wiring plan first. How will you
route your wiring so it is neat and easy to
service. Do you need to upgrade your
battery banks, electrical panel , etc.
-Install the big ticket items first- battery bank , electrical panel , etc
-Follow the ABYC wiring standard for color and size of wiring
- Bus bars are good. I installed hot and ground bus bars close to my panel and wired them back to the battery bank with appropriately sized wire
-Always crimp your connections and seal with shrink wrap
-Be very careful how you
route your wiring that you don’t create stress points
-Support the wiring with wiring ties
-Get a label maker and label both ends of rack circuit
- probably the best advice is to
work on one circuit at a time. Look at how the circuit is run at present. Can you improve on the routing? Can you make it more
water tight? Can you support it better? By working on one circuit at a time it kept me from getting overwhelmed with the scale of the
project. If I had a couple of hours I would run a new circuit and try to do it really well .
It sounds like a lot of
work but it gave me a lot of satisfaction to open my panel and show other sailors how well it was organized and my
electrical system became very dependable for the next 20 years
Best of luck!
