    Not many things are still 'on' with the PD open. One of the most 
common" gone to ground" components is my favorite, the lift motor.{Hint, the 
lift motor is still 'on' when the PD is 'open'. } Lighting wiring, toasted 
by the armature resistors, is another 'hot' item.
     Think of the double contactor replacement as an occupational therapy 
exercise. Increases dexterity. <G>
