I have the non-smart version of the Orion TR 12-30 DC-DC Isolated charger in campervan. My positive input wire is connected to one of the open locations on the battery of a MB sprinter van. I have the input and output grounds going to a common negative buss that is grounded to the vehicle chassis.
I'm little unclear what to do with the jumper plug. From my understanding this model doesn't have the engine detection on mechanism so a wire form the ignition switch will need to be ran to it to tell it when to turn on? I currently have the jumper wire in and Blue Sea Systems battery on/off switch I have to turn off power to the auxiliary battery banks does not kill the power which indicates that my auxiliary system is getting 12v from my vehicle battery via the DC-DC charger because the jumper is in?
