US spec English car indicators not working

[NigelStn]

I'm wondering if anybody can help here
I've finished rewiring my Aston Martin DB2-4 Mk I, but I cannot get the indicators working.
I have power to the direction indicator relay and flasher unit, the relay clicks when the indicator switch is turned. Both the relay and flasher are new and I'm pretty sure that everything is wired correctly. Does anyone have aclue as what could be the issue. See photo of indicator relay below.

It's multimeter time. You really do need to get in there and see where you've got volts and where you haven't.

+ve earth, I presume?

Yes +ve earth
And yesterday I bought a better multimeter, than my Screwfix one yesterday from Lidl! Only £10 and it's really good

There y'go, then.

Find out what point you stop getting -12v on the feed to the bulbs.

I usually end up with rusty bulb holders, that's a good place to start if you want to start tearing into things randomly rather than being systematic.

True - but tends to be really, really obvious...

Sorted
Thank you for all your inputs
Turned out to be a dry joint on one of the connectors on the new wiring loom
Just the clock to sort out now
