Adventure carburetor heater 950 Adventure
Mode of operation: to prevent the carburetor from icing at low outdoor
temperatures and high humidities, both carburetors are heated by one
heating element
each. The air temperature must be below 3-9ºC and
1
the ignition on for the heaters to operate.
Current flows via the ignition switch
temperature switch
4
continues to both heating elements
9ºC.
Checking the heating elements
Use a digital multimeter to measure the resistance of the heating
elements.
Set-point value: 5 - 10
NOTE: if the resistance is higher, replace the heating element.
Checking the temperature switch
Disconnect the connector
the resistance of the temperature switch (between the 2 yellow cables).
Set-point value: less than 1
Set-point value: 8
NOTE:
Ω
– If the resistance is ∞
– The temperature switch will switch on between 3ºC and 9ºC and off
between 10ºC and 16ºC.
– if no error was found and the carburetor heater still won't work,
check the ground supply to the carburetor by using a digital
multimeter to check the resistance between the carburetor and the
negative pole on the battery. The measured resistance should be less
Ω
than 1
.
