Just wondered if you added any fuses into the system, such as for the second battery from the Blue Sea relay or the supply to the fuse box?

Wow 3 batteries! You trying to run your own nuclur plant?

it's a 24v start - could run the accessories from the second batt but its needed for starting so want to be 100% safe due to what the vehicle is doing/where its going. the fridge would be fine off the second batt as it has the auto shut down but since it will be parked for days at a time and i'll need the fridge to be working i need the 3rd batt.

no, i'm trying to keep the connections to a minimum so I used the same diagram as provided with the relay. the aux fuse box is the only output from the aux battery and each item is individually fused.

i kept the car battery fuses as OEM, ie the mega fuse is still there for the starter
