Carburetor Heater Inspection; Carburetor Thermo-Switch Inspection; Throttle Position Sensor Inspection - Suzuki RV125 Service Manual

NOTE:
The apparent fuel level measured in the level gauge is higher
than the actual level in the float chamber because of meniscus
effect. (Meniscus is approximately 1 mm.)

CARBURETOR HEATER INSPECTION

• Disconnect the carburetor heater lead wires.
• Connect the positive + terminal of a 12 V battery to the termi-
nal of the carburetor heater and the battery negative - termi-
nal to the terminal.
• Check that the heater section A is heated in 5 minutes after
the battery has been connected.
• Measure the resistance between the terminals.
% 09900-25008: Multi-circuit tester
$ Carburetor heater resistance: 12 – 18 Ω Ω Ω Ω

CARBURETOR THERMO-SWITCH INSPECTION

• Cool the thermo-switch 1 with ice water and check for conti-
nuity.
% 09900-25008: Multi-circuit tester
$ Thermo-switch continuity: Below 8 – 14 °C Yes

THROTTLE POSITION SENSOR INSPECTION

Measure the resistance between the terminals as shown in the
illustration.
$ Throttle position sensor resistance: Approx. 5 kΩ Ω Ω Ω
NOTE:
When performing this test, it is not necessary to remove the
throttle position sensor.
Above 13 – 25 °C No
