Testing for a short with a test light or voltmeter
1. Remove the blown fuse.
2. Connect the test light or voltmeter across the fuse terminals in the starter relay. Turn the
ignition switch ON and check for battery voltage.
3. With the test light or voltmeter attached to the fuse terminals, wiggle the wiring harness
relating to the suspect circuit at various intervals. Start next to the fuse terminal a work
systematically away from the fuse terminal. Watch the test light or voltmeter while
progressing along the harness.
4. If the test light blinks or if the needle on the voltmeter moves, there is a short-to-ground at that
point in the harness.
BRAKE SYSTEM
The front and rear brake units are critical to riding performance and safety. Inspect the front and
rear brakes frequently and repair any problem immediately. When replacing or refilling the brake fluid,
use only DOT 4 brake fluid from a closed container.
Always check the brake operation before riding the motorcycle.
Soft or Spongy Brake Lever or Pedal
Operate the front brake lever or rear brake pedal and check to see if the lever travel distance
increases. If the lever travel does increase while being operated, or feels soft or spongy, there may be
air in the brake line. In this condition, the brake system is not capable of producing sufficient brake
force. When there is an increase in lever or pedal travel or when the brake feels soft or spongy, check
the following possible causes:
1. Air in system.
WARNING
If the fluid level drops too low, air can enter the
hydraulic system through the master cylinder. Air
can also enter the system from loose or damaged
hose fittings. Air in the hydraulic system causes a
soft or spongy brake lever action. This condition
is noticeable and reduces brake performance.
When it is suspected that air has entered the
hydraulic system, flush the brake system and
bleed the brakes as described in Chapter Fifteen.
2. Low brake fluid level.
WARNING
As the brake pads wear, the brake fluid level in
