0013 00
N OT E
Arc suppressors protect electrical components in machine. Arc suppressors are applied in order to dis-
charge electrical inductance of a component when other components within a circuit are operated.

1.
Place multimeter in DIODE test mode.
2.
Place red probe in red terminal (positive terminal) of multimeter.
3.
Place black probe in black terminal (negative terminal) of multimeter.
4.
Place red probe on Pin 2 of connector on arc suppressor. Place black probe on Pin 1 of connector.
5.
Multimeter should display a value between 0.5 and 1.0 VDC.
6.
Place red probe on Pin 1 of connector on arc suppressor. Place black probe on Pin 2 of connector on arc suppressor.
7.
Multimeter should display OL.
8.
If conditions listed in steps 5 and 7 do not exist, component should be considered faulty. Component will not provide
adequate protection.
9.
Replace component if component has failed.
