Hi, Edd — the negative side of the charger output can go straight to the main
negative bus bar; this should have a large conductor straight to the negative
sides of both the house and start banks. DO NOT just grab any local ground
point, as the connection from it to the battery may not be

That’s what I thought. An installation manual threw me for a few. . . .
Thanks for the clarification.

Listers,
For a shore-powered battery charger, do the red and black wires need to run to
the battery or can the red run to the battery and the black to any common
ground on the boat?
In other words, does the black need to connect directly to the negative
terminal on the battery?
All the
Josh — you’re correct, thanks for the clarification. The main negative bus
needs to be on the “Load” side of the shunt, if you have one installed. And
Joel: the negative side of all DC systems in the boat should terminate at one
point. This should include batteries (or banks of them), the DC
