Test Ground Strip Resistance
See F IG . 22.. Using an ohmmeter, measure the resis-
tance 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
See F IG . 23.. 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.
