<p>An electronically controlled locking differential (10) includes an electromagnetic coil (50) and a control system (56) adapted to control operation of the differential (10). The control system (56) has a module (58) adapted to be mounted under a dashboard of a vehicle and a circuit (78) electrically interfacing with the module (58). The circuit (78) has a latching switch (64) that is electrically connected to first and/or second sources of power and adapted to provide latching power of the differential (10). A latching component (84) is electrically connected to the latching switch (64) and adapted to provide latching power of the differential (10). The circuit (78) is disabled when power to the control system (56) is turned off and in "standby" mode when power to the control system (56) is turned on. Upon the latching switch (64) being activated, current flows through the circuit (78) to activate the latching component (84), and the differential (10) is actuated.</p> |
