From other sources I am told that this is correct. The green wire is OK to attach to an engine terminal, or a thru hull
. A few boats here don't attach it at all. Most other wind
gens only have the two wires, red and blk.
Interesting that with this electrical
connection on the batteries, it was suggested to have a set of jumper cables
on board. If the batteries are all left on and drained, it would take a very long time to charge both the house and engine. An option is to charge the house and use the jumper cables
to start the engine, or disconntect the house and tie directly to the engine or use the cables.
