GL1200 Ltd. and SEI Repair -- The GL/GR Sensors

First measure at the ECU Connector terminals.

For the Gr Sensor, measure between the #8 and the #24 Terminals of the ECU
Connector. The resistance should be 140 - 180 Ohms.

For the Gl Sensor, measure between the #7 and the #24 Terminals of the ECU
Connector. The resistance should be 140 - 180 Ohms.

If you have these resistance measurements, then the Gl/Gr Sensors are
probably OK. If you have a reading significantly different from these, then
find the Gl/Gr Sensor Connector at the front left side of the frame. After
you have found the connector, a WHITE 4 pin connector on the front top of
the frame. (You will probably have to remove the Coils) disconnect it, and
take readings at the terminals between the WHITE w/Yellow Tube wire and the
YELLOW wire .

     The reading should be 140 - 180 Ohms.

Then measure between the BLUE wire and the GREEN w/BLUE & WHITE wire.

     The reading should be 140 - 180 Ohms.

Then measure each of the four terminals to ground.

     There should be NO continuity.

If your measurements are much different than these, REPLACE the GL/GR
Sensors as a pair. They are located under the cover at the back of the
right side Cylinder Head.

If your measurements are about the same, then check the wiring harness from
the Gl/Gr Sensor Connector back through the various connectors to the ECU.
Correct any wiring harness problems, and then repeat the first test.

GL/GR SENSORS AIR GAP

Remove the cover plate from the Gl/Gr Sensors on the right cylinder head.
Align the rotor projection up with the sensors, and set the AIR GAP to 0.58
- 0.62 mm (.023 - .024 in.) Replace the cover.
