Hello,
I am adding a 12V DC fridge and a small number of DC devices to our ARE DCU Camper shell on our Tacoma. (Engle Fridge, LED light, USB port for charging cell and a port for a Fantastic Fan to plug into)
Inside the Shell:
I have two 12V AGM batteries wired in parallel. Wired off the positive side is a Blue Sea Battery disconnect switch. (Between the positive post and the battery disconnect is a 30 amp fuse) From the Battery disconnect switch, I then feed a Blue Sea Fuse block.
At this time, I ran a #4 wire from the negative side of the batteries (NO shunt installed at this time) directly to the trucks chassis after removing the paint where I bolted the lug to.
The Blue Sea Fuse block negative lug connects to the negative side of the batteries just like the chassis return. All my 12V DC loads will have two wires (pos & neg) to the device and back to the blue Sea fuse block with an appropriate sized fuse. At this time, I am not using the trucks alternator to charge the batteries as I will be relying on solar for charging the batteries. So "no" DC to DC charger or Isolator.
I have read that many do not believe the negative side of the batteries needs to have a return to the chassis while others say nothing wrong with this and they would wire as I have done.
Based on the experience of others here, is my setup satisfactory? Am I OK to leave my Chassis return? Any advice or help would be much appreciated!
Thank you,
Jon
