Claim 0:
1. A system, comprising:
a primary coil wound around a moveable magnetic core;
at least one secondary coil wound around the moveable magnetic core in one continuous direction and magnetically coupled with the primary coil; and
a controller operatively connected to determine a position of the moveable magnetic core and configured to detect a fault across the secondary coil,
wherein the secondary coil includes a first side line, a second side line, and a center-tap, wherein the first side line and the second side line of the at least one secondary coil are 180 degrees out of phase relative to one another, wherein the controller is configured to perform a built-in-test (BIT) to detect the fault across the secondary coil, wherein the controller is configured to sample a voltage of the first side line with respect to the center-tap and a voltage of the second side line with respect to the center-tap and determine a sum voltage of the first side line and the second side line.
