In dualmode the two battery system should be tied together for charging.
In dual mode there should be power to the small post of the relay.
To test put switch in center position. Measure voltage on the large terminals should be different. Have helper hold switch in mom position the relay should energize and measuring voltage on large terminals it should be the same. If it is not bad relay.
If yes, put switch in dual mode. Relay should energize and voltages should be the same.
