Indicator/flasher issue/wiring S2a

Hello all
Can anyone help me with wiring my indicators on my 2a resto project im not great with electrics! basically they have not worked since ive had the vehicle ive got power going to the relay and to the stalk/switch, when i switch the stalk relay clicks onces but no lights come on ive checked earths and bulbs etc! i would rewire them if i had a basic wiring diagram for indicators only?? any suggestions?? also it has a three pin relay but only two wires is this correct?
Thanks
Darren

Relay shagged.

That is not the title of an event at the porn olympics...but it should be.

Got issues with mine, the flash speed is all over the place so assumed relay gone.

Is it worth using a generic one or genuine one?

any two pin flasher should do inline with fed to switch
