Patent ID: 8100805

Claim:
An electronically controlled locking differential comprising: an electromagnetic coil; and a wire harness adapted to logically control operation of said differential and including: a circuit having: a latching switch that is electrically connected to a first source of power and adapted to provide latching power of said differential; and a double-pole, double-throw control relay that is electrically connected to said latching switch and includes a first switch, a second switch, and a coil, said second switch being adapted to “jump” said latching switch; wherein said circuit is disabled when power to said harness is turned off and in “standby” mode when power to said harness is turned on and, upon said latching switch being activated, current flows from a starting point of said circuit through said circuit to activate said relay, said first switch closes to energize said differential, said second switch closes such that current “jumps” said latching switch, and said differential is actuated.
