DESCRIPTION
This test will help determine if the “power section” of the switch boards are functioning cor- rectly. This test will NOT indicate if the entire PC board is functional. This resistance test is preferable to a voltage test with the machine energized because these boards can be damaged easily. In addition, it is dangerous to work on these boards with the machine energized.
MATERIALS NEEDED
3/8” Nut driver 3/8” Wrench Analog
This procedure should take approximately 20 minutes to perform.
