Here's the finished result. I wish I could do something better with the NMEA 2000. Simnet is such a better system, much neater to wire. (and I have a Simnet network plugged into the NMEA 2000 one, works perfectly)
Now I just have to figure out if having the Xantrex charger chassis grounded to the engine heat exchanger (yes, you read correctly) is a good thing!
There should be only one DC negative ground on the engine, I'm guessing you have more than one if the heat exchanger is involved.
Is that white thing in the bottom of the photo a battery box ? if so, either it or the charger has to be moved. You cannot mount a charger over batteries.
