CHECK 3: H.T. COIL CHECK:
Use the tester in the Ohms scale to check the continuity of the windings. The approx. values are as follows:
L.T. SIDE: 3-6 OHMS
H.T. SIDE: 12 – 15 KOHMS
Note: This method is NOT able to detect partial failures in the isolation
CHECK 4: TIP OVER SENSOR CHECK:
Remove the sensor plus grommet from its housing and tilt it sideways at an angle greater than 45
°
to simulate
a fall.
The standard reading must be 0-1 Ohms.
CHECK 5: THERMISTOR CHECK:
Check the sensor resistance, using the tester in the Ohms scale.
At 20 degrees centigrade the resistance must be about 2450 Ohms
At 40 degrees centigrade the resistance must be about 1114 Ohms
At 60 degrees centigrade the resistance must be about 584 Ohms
At 90 degrees centigrade the resistance must be about 245 Ohms
CHECK 6: THROTTLE SENSOR CHECK:
With the sensor installed, check as shown in the figure (with the throttle in any position)
A:Valore standard:
2,9 – 5,3 Kohm
