Turn singals inoperative

[Firestick]

07 Busa, turn signals and hazard lights inoperative.
The fuse is good, the relay and left handlebar switch has been replaced and there's continuity with all the wires. Still no go.

Is there a diode in the cluster that if burned out will prevent this from working?

HELP!! I can't spend any more money on guesses.

Thanks!

There is a couple diodes in the side stand switch/turn signal relay. I'm not sure the relay is located though.

are all bulbs still factory? have you check the relay on the left front? any mods to the lights?

You checked all the grounds?

You checked all the grounds?

Very important especially if you are running something other than OEM signals.

thanks for the advice so far.
The relay is new, two of the turn signals are new OEM but will have to check other bulbs. No other light mods.
Will also check grounds to make sure clean and tight.

You mentioned above the left switch has been replaced, was that before or after you started having troubles?

The reason I ask is that I was helping lil_schmitty, turns out he'd swapped out switches for a different year and though it has the same connector the wiring is different.
