H 216 or 22 Daysailer Electrical Pkg

[Joetul]

I have the factory installed electrical package. New boat.
However I cannot get the electrical system to work. I suspect I am missing a ground wire. How many ground wires run to your battery? At present I have only one ground wire which runs to the battery charger. Can anyone tell me where the main ground wire runs from the battery. Any suggestions?

According to the SBO download found on this forum at

You should have three ground wires. One to your outboard alternator, one to the charger and one to your buss bar which is normally in your distribution panel.
