Diode board et al wiring

[Wrigsby1]

Hi

I am finally getting the 100RT back together again and have one wire in the vicinity of the diode board/alternator without a home... I have scammed another pic off the net and ringed the offending black wire...

Thanks in advance for putting it in its place...

Is it the wire to the starter motor ?

Cheers, I'll check... Serves me right for being too slow... Would make sense on why I can't find a pic of it attached to anything...
