Diode Circuit Inspection


The resistance should be low in one direction and more than 10 times as much in the other direction. If any diode shows low or high in both directions, the diode is defective and the relay box must be replaced.

NOTE

The actual meter reading varies with the meter or tester used and the individual diodes, but generally speaking, the lower reading should be from zero to one half the scale.

Caliper Fluid Seal Damage
The fluid seal (piston seal) [A] is placed around the piston to maintain clearance between the pad and the disc. If the seal is in a poor condition, it could lead the pad to wear excessively or the brake to drag, which may cause the temperature of the discs or the brake fluid to increase. Re ...

Water Temperature Sensor Inspection
Remove the water temperature sensor (see Water Temperature Sensor Removal/Installation in the Fuel System (DFI) chapter). Suspend the sensor [A] in a container of coolant so that the temperature-sensing projection [C] is submerged. Suspend an accurate thermometer [B] with temperature ...

Tire Air Pressure Inspection
Remove the air valve cap. Measure the tire air pressure with an air pressure gauge [A] when the tires are cold (that is, when the motorcycle has not been ridden more than a mile during the past 3 hours). Install the air valve cap. Adjust the tire air pressure according to the specifi ...
