The diode pack has no effect on the Igniter operation - only the 'start' interlock
The starter is interlocked to EITHER the 'Neutral' signal, or the combo of SideStand & Clutch Switches if in gear.
The Igniter is interlocked to EITHER Neutral OR SideStand switch - if either of these is present, there is no interlock on Igniter
or conversely - to be interlocked, the bike must be in gear with side-stand in down position.
If you have neutral light, unlikely your igniter is being interlocked.
If your starter operates under either condition (bike in Neutral or if in gear, side-stand up plus clutch lever pulled) then there is nothing wrong with diode assembly
The voltage on each of the diode cathodes (the non-common terminal)will be 'zero' with respect to battery negative when the neutral switch is made (the one the Black/White is connected to) and the combination of clutch switch and side-stand made for the other (also Black/Pink wire, but the one that is connected to the clutch switch)
Either one of these will give ~ 0.7V on the common anode connection (the one Black/Pink is connected to) when those switches are applied which goes to the starter relay
Again, diode pack itself has no impact on the Igniter interlock.
But you MUST have Neutral signal OR SideStand up for Igniter to work.
