5 PAIRS OF RESISTORS

CHECK VOLTAGES BETWEEN EACH TERMINAL AND FROM EACH RESISTOR TO CASE GROUND

5.Locate two sets of two resistors on the left side of the machine and three sets of two resistors on the right side of the machine. See Figure D.1. Do not touch the resistors or any other internal machine component. Using a DC voltmeter, check for any DC voltage that may be present across the termi- nals of each resistor and from each resistor to case ground (20 measurements in all). If a voltage is present, be careful not to touch these resistors.

WARNING

ELECTRIC SHOCK can kill.

•Proceed with caution being care- ful not to touch any internal machine components during the discharge procedure.
