Clutch Diode Information ( ST1100 )
Symptoms: Engage gear and the neutral light comes on and then goes out as clutch lever released.~~~
Here's the picture of the clutch diode location (I marked the diode to ID the spades to their colored wire leads):

Here's the clutch diode 'in situ' with the wire loom tape peeled back:

1N5402 or # 276-1143
3 amp, 200 v PIV
$1.69 each.

Need two diodes ( 1N5402 )
(http://rsk.imageg.net/graphics/product_images/pRS1C-2160488w345.jpg)
and some insulated crimp terminals ( 3 x red ).
(http://images.maplin.co.uk/300/jh89.jpg)
Twist together the cathodes ( banded end ) and crimp on an insulated terminal.
Crimp insulated terminals to each of the remain anodes ( Un-banned end )
Looking at wiring diagram below:
(http://www.st-riders.net/aow/AOW%20-%20ST1100/Clutch%20Diode%20Information%20-%20ST1100/Pic%201.jpg)
The end with the twisted leads into a single insulated terminal connect to the GREEN wire.
The remaining diode ends connect to the GREEN\RED wire and the other wire.
