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:



Honda part number/noun-nomenclature:
31700-196-000 / RECTIFIER  (about $16 USD)

OEM diode pack can be replaced using general purpose diodes available at Radio Shack or any other electronic component source.

Radio Shack:   http://www.radioshack.com/product/index.jsp?productId=2062578

1N5402 or # 276-1143

3 amp, 200 v PIV

$1.69 each.

~~~

Need two diodes ( 1N5402 )


and some insulated crimp terminals ( 3 x red ).


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:


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.
