Wiring the Bi-Directional Isolator Relay diesel-2

At the BIRD there should be a GEN spade with a wire. DISCONNECT that GEN wire and the BIRD should allow bi directional charging as long as the Converter(Inverter/Charger) supply voltage is OVER 13.2 volts. Remember, BI directional when on Shore/Gen ONLY happens when the House charging system supplies over that 13.2 volts. Once the Charging goes to float(usually this is less than 13.1), the BIRD drops out the charge to the chassis side batteries. Doug
