Signal lights not working

[STWing]

Recently bought a '75 Goldwing that came with a fairing, which I quickly removed. Took a while to sort out the wiring, as I'm quite a novice, but using the electrical diagram I'm almost positive I have everything hooked up correctly. Unfortunately when I turn the key, only the left front signal light comes on, when I switch to left blinker, it blinks once, gets brighter, and just stays on. No action on the right side, and no action for either of the rear signals. I'm pretty sure all the bulbs are ok, and I did try new ones too. No change. Any idea what the issue might be? Cheers!

turn signal funkiness often comes down to just a bad ground. if you haven't already done so, remove and clean all grounds. inspect the bulb sockets themselves. also, there's a good chance the switch itself is gummed up with a cocktail of dried grease and dirt.

Your flasher wire could be faulty or not connected at all. You've blown a fuse. Your relay connection is not functioning correctly. One bulb of the bulbs has burnt out.

Have a few other things on the go, so still trying to figure it out, but I think I'm actually missing some ground wires. It's hard to know for sure because the bike is new to me and I don't know what's actually supposed to be there.
