Silicon rectifier

HiAll. After taking a year off to move house to Norfolk and do it up I am now back in the garage
Set up the engine which now runs like a watch Easy to start idles nicely Only problem it won’t start off the button When I short the solenoid it starts. Have checked the solenoid across the battery and it clicks so switching
The Green and Red wire from the solenoid goes to the Silicon Rectifier A new loom has been fitted but the rectifier differs between the old and new loom  Will this be the problem? The supplier of the new loom suggested trying another rectifier Which I have but still no go see attached photos the image of the diode differs -  +.  +. - with a diode allowing current flow only in one direction this can’t be right  Help not much hair left Cheers Ross

Hi  Photos one/two  show the old loom with g/r to positive through the diode to negative
     Photos three/four show new loom with g/r  to positive but the diode the wrong way
     Is it as simple as removing the wires from the plug and reversing them?????   and fitting the old rectifier in correct orientation + at the top of the diode?
   
    Cheers Ross

That is a silicone diode, NOT a rectifier. It is part of the starter safety circuit (blame the yanks and the sue everyone culture) Basically it locks out the starter motor unless the clutch is pulled in or the bike is in neutral. Do you have the clutch switch (between the lever and switchgear) fitted and connected? If not, it won't play nicely, connections for it are in the headlight shell.

Hi Mr Hairy,    Yes all connected up Just No go   
                  In the manual , following the dark green/red it goes to the clutch switch via the headlamp With a junction to what they call a Silicon Rectifier showing a picture of a diode Is this wrong !!!!  Sorry electrickery not a strong point   Everything works except the starter motor yet getting power to the solenoid via the yellow/red wire from the starter button And the solenoid checks out as good So looking at the dark green/red wire for problems      Ross

 Hi OJ 
        When clutch switch disconnected in the headlamp bowl i put a meter across them to test continuity
        When the clutch lever is pulled i do get continuity so assume all good  and working with the switch

       Cheers Ross
