I have installed an Orion 12/12-30 Isolated in my trailer connected to my Toyota Highlander with the tow package and 150a smart alternator. I'll be having upgraded 6 AWG run next week from the alternator to the trailer, but to start with I've just hooked it up to the 10 AWG power wire in the 7 pin connector. It comes up fine in Victron Connect, shows 12.8 volts from the battery with the car off. I turn the car on, I get 14 volts, the Orion detects it and starts charging. But then the input voltage starts dropping steadily and then drops enough for the orion to turn off. It stays at zero whether or not the car is running until I unplug the 7 pin. I plug back in and it comes up again, then tails off again. If I disconnect the power wire from the Orion and measure it, it stays at 14v with the car on. Anyone have any idea what the interaction between the Orion and the car power system is that is causing this?
