[Al Skierkiewicz]

If there is a short downstream from a controller, it won't present itself during a resistance check from either of the power input terminals on the PD to frame. This can occur with a wiring short to frame or with a defective motor. the only check for those issues are a continuity check from the output of each controller to frame. In this case though, the fault doesn't actually cause an issue until the motor is commanded except for Jaguars.
