I want to add a Victron monitor to my 1999 30' Classic. The difficulty is getting access to the negative cables out of the batteries.
In this model, my two batteries are inside the trailer underneath either side of the front gaucho - so they are about 4 feet apart. They are accessed from the outside via two separate doors (see photo). Inside the door is a fully enclosed plastic box to keep battery gasses from getting into the trailer (I now use AGM).
Everything pretty much comes together in the center of the trailer behind the gaucho, on the inside of the front bulkhead and on the floor.
The positive cables come together on a bus bar (?), along with the positive from the converter. They run in the open and I can track these cables easily.
However, the two negatives from the batteries are routed behind the bulkhead and only come together at the
12V Distribution Panel (also behind the gaucho). See photo. You can see the curbside one coming in at the bottom (thick black). The streetside one comes in on the other side (but you can't see it). I'm pretty sure one of the white cables is from the converter.
I cannot figure out how to isolate all of these grounds and make them go through the Victron shunt... without some major dismantling and extra 'stuff'.
Suggestions would be appreciated.
I'm also adding a Zamp 180W panel to reduce some of the generator time when we're on multi-week boondocking trips. It looks like I can pretty easily add the Zamp connector and run one wire to the positive side of one battery and the other to the negative side of the other battery (I think this is a correct way).
Thanks!
