Remove the luggage box (page 2-5).
Disconnect the engine coolant temperature (ECT)
sensor 3P (gray) connector.
Ground the Greedblue wire terminal of the 3P con-
nector with a jumper wire.
Turn the ignition switch to ON and check the tem-
perature gauge.
The gauge needle should move to "H".
If the needle moves, check the ECT sensor (page

If the needle does not move, check as follows.
Remove the front handlebar cover (page 2-1 1).
Check the Greedblue wire for continuity between
the temperature gauge and ECT sensor 3P connec-
tor.
There should be continuity.
Disconnect the Greedblack wire terminal of the
temperature gauge by removing the terminal screw.
Check for continuity between the Greedblack
(ground) wire terminal and ground.
