Abstract: An electrical system (12) is provided for an automotive vehicle (10) having a first power source (14) with a first positive terminal (16) and first negative terminal (18). A second power source (20) having a second positive terminal (22) and a second negative terminal (24) is also provided. A common electrical node N2 is coupled to the first negative terminal and the second positive terminal. A first load (26) is coupled between the first positive terminal and the second node N2. A second load (30) is coupled to the positive terminal. A switch (SW3) is coupled to the second positive terminal (22), the second negative terminal (24) and the second load (30). The switch (SW3) has a first position electrically coupling the second load to the second positive terminal and a second position electrically coupling the second negative terminal to the second load (30).

Abstract: A circuit (10) for connecting a power distribution bus (14) to a battery (12) has a connector circuit (20) and a switch (40). The battery has a positive battery terminal (16) and a negative battery terminal (18). The switch (40) has a control terminal (46), a first terminal (42), and a second terminal (44). A contactor circuit (48) is coupled between the battery (12) and the power distribution bus (14). The contactor circuit (48) has a solenoid (50) and a plunger switch (52) that is operably coupled by solenoid (50). In one embodiment of the invention the connector circuit has a switch (38) used to allow the connector terminals to be coupled at different times to the circuit. In the second embodiment, different length terminals may be used to enable coupling of the battery terminals at different times.
