Brakelight Switch

TESTING/REMOVING
1. Disconnect the brakelight switch gray and brown
two-wire connector (located near the brake lever).
2. To test the brakelight switch, connect one tester lead
to the brown terminal; then connect the other lead to
the black terminal.
3. With the brake lever compressed, the meter must
read 1 ohm or less resistance. With the brake lever
released, the meter must read OL (open). If the meter
does not read as specified, the brakelight switch is
defective and must be replaced.
4. To remove the switch, remove all brake fluid from
the reservoir; then remove the torx-head screws
securing the reservoir to the piston assembly; then
pry the brake switch from the piston assembly.
