I’m installing the electrical system
from scratch on an older csk catamaran
that has a single
House bank is Li, starter is lead acid. They are independent (no combiner) except for a dc-dc charger
(Renogy), that has appropriate chemistry settings. Both batteries
are led to a common negative bus as will be the AC system.
As the starting battery
is connected to the negative bus it is “grounded” to sea water
when the engine
is down. Bu, at anchor
and while sailing engine
is up out of the water
, do I need a separate grounding wire? This is tricky as seacocks are marelon.
Thanks in advance for your help!
