Test Ground Strip Resistance; Test Cylinder Resistance - Graco WB3000 Instructions - Parts Manual

Test Ground Strip Resistance

Using an ohmmeter, measure the resistance between
the latch housing (206) and the ground lug (214).
The ground strip is grounded through the cart back
to the ground lug. Resistance must be less than 100
ohms. If greater than 100 ohms, replace the ground
strip (240).

Test Cylinder Resistance

Remove the enclosure door. Using an ohmmeter,
measure the resistance from the pump (209) to the
ground lug (214). Resistance must be less than
100 ohms. If greater than 100 ohms, replace the
grounding cylinder.
