1.4. If slight pressure on the tab breaks continuity,
adjusting the tab by bending it downward will
enable the switch to work correctly.
See Figure 1.4.
1.5. If the switch does not break the ground path
(meter reading: near 1.0 ohms, or “OL” indicates
open contacts, breaking ground path) when the
plunger is pressed, replace the switch.
1.6. The switch should complete a path from the
magneto to ground when the plunger is up.
See Figure 1.6.
NOTE: If the switch fails to ground out the mag-
neto when the plunger is up, it would be possible
to run the engine without a blower chute or col-
lector bag in place. This is unsafe.
1.7.
1.8. If the switch fails to ground the magneto, identify
if the switch itself is at fault, or if a bad connec-
tion exists between the switch and ground.
NOTE: A lock tab secures the plug to the switch.
The switch must be removed to reach the lock
tab.
1.9. Remove the switch from the frame using a 5/16”
wrench or driver. See Figure 1.9.
1.10. Test the switch independently. It should show
continuity with the plunger up. See Figure 1.10.
