If there is no continuity, replace the respective parts. NOTE: When performing this test, it is not necessary to remove the combination meter.ELECTRICAL SYSTEM _6-34 ‘TURN SIGNAL (L) ‘SPEEDOMETER TACHOMETER Probe of Probe of t NEUTRAL i a i ‘TURN SIGNAL (R) IGNITION ILLUMINATION © SPEEDOMETER SPEEDOMETER, GROUND Blank Blank Blank NEUTRAL HIGH BEAM @ TURN SIGNAL (L) TURN SIGNAL (R) NEUTRAL, HIGH BEAM FUEL METER 245 6789 7T\N SS 12.13 14 18 6 V7 1819 10 Blank TACHOMETER, ow FUEL METER Blank Blank Ban Blank6.35 ELECTRICAL SYSTEM FUEL METER INSPECTION To test the fuel meter, perform the following tests. Test 1 This test will determine if the fuel meter is operating. Remove the fuel tank. (See p. 4-2.) * Disconnect the fuel level gauge coupler. * Connect a jumper wire between the B/W and Y/B lead wires coming from the wire hamess. © Tum the ignition switch on. © The fuel meter's needle should go past the “F” (ull) line. Test 2 This test will determine the accuracy of the fuel meter in the “ {empty) and “F" (full) positions. © Connect @ 103-117-ohm resistor between the Y/B and B/W lead wires. © The fuel meter is operating correetly if the needle moves to of below “E" (empty) when the ignition switch is turned on. '* Replace the 103-117-ohm resistor with a 1-5-ohm resistor. ‘© The fuel meter is operating correctly if the needle moves to or above “F* (full) when the ignition switch is turned on, If either test detects a malfunctioning fuel meter, replace it. FUEL LEVEL GAUGE INSPECTION ‘# Remove the fuel level gauge. (See p. 4-4.) © Measure the resistance at each fuel level gauge float posi- tion « Ifthe resistance is incorrect, replace the fuel level gauge with anew one, ‘ The relation between the position of the fuel gauge sending unit float and the resistance is shown in the following table. Float position Resistance F (Full) 159 12 Approx. 32.5.2 E (Empty) 103-117 & @® 150.8 mm (5.94 in) ® 75.0 mm (2.95 in) © 12.0 mm (0.47 in)ELECTRICAL SYSTEM 6-96 ‘SPEEDOMETER INSPECTION If the speedometer, odometer or tripmeter does not function property, inspect the speed sensor and the coupler connec- tions. If the speed sensor and coupler connections are OK, replace the combination meter with a new one. SPEED SENSOR INSPECTION ‘¢ Remove the upper fairings. (See pp. 5:2.) ‘* Disconnect the speed sensor coupler. ‘© Remove the speed sensor ©. '* Connect @ 12 V battery (between O/R and BNW), 10 k2 resistor (Between O/R and P) and pocket tester (tester @ probe to O/R and tester © probe to P) as shown. O/R : Orange with Red tracer BIW: Black with White tracer Po: Pink (09900-25008: Multi circuit tester set (GG)! Tester knob indication: Voltage (==) ‘* Move a screwdriver back and forth across the pick-up sur- face of the speed sensor. The voltage readings should cycle as follows (0 V > 12 V or 12 V0 V). Ifthe 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).

(See p. 3D-2.) # Disconnect the oll pressure Green/Yellow lead wire from the oil pressure switch ‘® Tum the ignition switch to the “ON” position. ‘© Check if the oil pressure indicator lights up when grounding the Green/Yellow lead wire. If the oil pressure indicator does not light up, check the cou- plers. If all of the connections ate OK, replace the oil pressure indicator with new one. After checking the oil pressure indicator light, install the sig- nal generator cover. (See p. 30-3.) mez Co
