Speed Sensor Inspection; Oil Pressure Indicator Inspection - Suzuki GSF1250 Service Manual

9C-9 Combination Meter / Fuel Meter / Horn:
Installation
Install the speed sensor in the reverse order of removal.
Pay attention to the following points:
• Tighten the speed sensor mounting bolt to the
specified torque.
Tightening torque
Speed sensor bolt (a): 6.5 N·m (0.65 kgf-m, 4.7 lb-
ft)
• Route the speed sensor lead wire. Refer to "Wiring
Harness Routing Diagram in Section 9A (Page 9A-8)".

Speed Sensor Inspection

Inspect the speed sensor in the following procedures:
1) Remove the speed sensor. Refer to "Speed Sensor
Removal and Installation (Page 9C-8)".
2) Connect a 12 V battery (between B and B/W), 10 kΩ
resistor (between B/R and B) and multi-circuit tester
(tester (+) probe to B and tester (–) probe to B/R) as
shown.

3) Move a screwdriver back and forth across the pick-
up surface of the speed sensor. The voltage
readings should cycle as follows (0 V → 12 V or 12 V
→ 0 V). If the voltage reading does not change,
replace the speed sensor with a new one.
NOTE
While testing, the highest voltage reading
should be the same as the battery voltage (12
V).

Oil Pressure Indicator Inspection

Inspect the oil pressure indicator in the following
procedures:
NOTE
Before inspecting the oil pressure switch,
check if the engine oil level is correct. Refer
to "Engine Oil and Filter Replacement in
Section 0B (Page 0B-10)".
1) Disconnect the oil pressure switch lead wire (1) from
the oil pressure switch.
