Mid-Mount Z Service Manual 7 - 33
ELECTRICAL SYSTEMS
Purpose
To shut the engine down when the tilt limit has been
exceeded.
How It Works
A small amount of mercury is contained in the switch.
When the tilt angle of the unit is less than 60°, the
mercury connects the contacts in the switch. When the
tilt angle exceeds 60°, the mercury flows away from the
contacts causing the switch to open.
Testing
1. Connect an ohmmeter across the switch.
2. When the switch is vertical, the meter should
show continuity.
3. Tilt the switch 60°. The meter should show open
circuit.
