Turn signal question was created by Grumman41

Thanks to the help from members my wiring issues are really close to being sorted out. My front and back turn signals on the right side are considerably weaker than the left. Maybe a ground issue? I’ve cleaned the grounds everywhere I can, not sure where else to look?

What type of flasher relay are you using, original or modern? If original, there could be dirty contacts within that causing you problems. You could buy a modern TWO pin 6v replacement (they are cheap) and see if that improves matters.

Where did you connect the "P" terminal?

If only one side, my guess is dirty switch contacts... Caig Deoxit isn't cheap but a little spray into the contacts and cycle the switch works wonders and is a real time saver over disassembly and cleaning.

I’d say you’re probably on the right track with the switch contacts. I did take the turn signal switch apart, wire brush the contacts and spray with contact cleaner. The issue is probably the phenolic part that holds the contacts, it is warped from heat and age. Probably not making good contact on one side, this may be a hard part to source.
I’ll probably try “manually” making that contact to see if that helps.

Edit: I don’t remember which was the P but brown to brown and white- brown to same and remainder to black ground.
