Warning Horn System
Models Equipped with Test Button
(3 Cylinder Only)
DESCRIPTION
Major components of the warning horn system are an
ignition switch, warning horn, low oil sensor,
powerhead temperature sensor, and warning horn
test button.
With the ignition switch in the “Run” position, electrical
current is routed thru the warning horn and supplied
to the powerhead temperature sensor, low oil sensor,
and warning horn test button. If the powerhead
overheats, the oil level in the oil tank drops below
approximately 1 quart (.95 liter), or the warning horn
test button is depressed, the electrical circuit
completed, and the warning horn will sound.
WARNING HORN SYSTEM CHECK
IMPORTANT: Warning horn will sound if power-
head is overheated or if oil level in oil tank has
dropped below approximately 1 quart (.95 liter).
1. Turn ignition key switch to “Run” position.
2. Depress test button. Warning horn will sound if
system is functioning properly.
3. Turn key switch to “Off” position.
