	6. Locate the #9 and #12 terminals, identified by the	FIGURE D.3 – RESISTORS WITH LEADS
	“Discharge” labels, on each of the four Switch	CONNECTED

Boards. See Figure D.2.

7. Using insulated, needle nose-type jumper leads and insulated gloves, connect one jumper lead to one end of the resistor obtained in step 4. Connect the other jumper lead to the other end of the resistor.

8. Carefully connect the needle nose end of one of the jumper leads to terminal #9. See Figure D.3. Connect the needle nose end of the other jumper lead to terminal #12. Terminals #9 and #12 are indicated by the “Discharge” label. Leave resistor connected for 10 seconds. DO NOT TOUCH TER-

MINALS, RESISTORS, OR ANY INTERNAL MACHINE COMPONENT DURING THIS PROCE- DURE!

9.Check voltage across terminals (9 and 12) with a DC voltmeter. Terminal 9 has positive polarity and terminal 12 has negative polarity. Voltage should be zero. If any voltage remains, repeat this capac- itor discharge procedure.

10.Repeat discharge procedure (steps 7, 8 and 9) for each of the other three Switch Boards.
