1973 Triumph Bonneville 750 This might be a tough one....the right turn signal did work until I took the switch apart. Because the left side didn't work. The only thing I did was use some emery cloth on the points just to clean them up. The green & white and red & white wire's are not hot but the other three are. Where do I begin?
Look at the points you've cleaned up and check that you've not left some crud there. Get your circuit tester out and check for continuity, Or by "hot" does that mean you done that already, You might have snapped a solder or the earth wire is loose.
Ok...waiting on parts now. Is there away to get the turn signal switch to move easier...up and down? It's a bugger to get it to move sometimes.
I just make sure that the moving parts are nice n smooth and dab a little lube on them. Also worth going through all the earth connections to make sure they are clean.
