'03 650 CS Turn Signal Issue

[bhempel63]

All stock, no farkle / bling

Switch on for right turn: both front / rear turn lights flash normal and normal flash from indicator at instrument cluster.
Switch on for left turn : both front / rear on BOTH sides flash normal speed but no indicator flash at instrument cluster.
Removed lamps from right signals, still no indicator at cluster and obviously no right signals flashing.

I have not disconnected right side wire at switch yet or at connector behind triple tree but will try this tomorrow.

Any thoughts????? Bad switch?

Thanks

Traced problem to left side diode for signal / hazard flashers

Anyone know the specs / ratings for these diodes? They are the gray plastic housed units. Current OEM list price is $45 & change

Original diode is a “BYV27-200” rated at 200V -2A
Found one rated just over @ local brick & mortar retail for under $2.00
Many online for pennies.
Now to go ride....
