Charles,

Q1. Is it correct to assume that the only power the backbone should have is to the converter?
A1. Yes

Q2. It appears that the original system had several sources, apparently each major component supplied power. I'm wondering why any source would not be sufficient?
A2. Powering the system from both the SeaTalk and SeaTalkng/NMEA 2000 sides can result in a ground loop. Within systems featuring both a SeaTalk bus and a SeaTalkng / NMEA 2000 backbone, the best installation practice calls for the SeaTalk bus(ses) to be powered via the SeaTalkng / NMEA 2000 backbone via the SeaTalk socket the backbone's SeaTalk to SeaTalkng Converters.

By ensuring that the system is networked in this manner, it will also prevent excess power passing through the SeaTalk to SeaTalkng Converter(s).
