Ricky, with due respect, time to think not buy something. Did you say the r/h flashers are working? If so, there is a wiring issue on the left. Buying a new relay or some diodes will not fix it. Most wiring problems are due to poor earth connections.
In logical terms - a physicist would tell a different story that is not relevant here - current flows from battery +ve via the fuse box to each component and then back through the frame to battery -ve to complete a circuit. Bad earths are common. For example, an earth to the handlebar or headlamp shell should not be trusted because the whole front end of the bike is only connected by the steering bearings - a set of ball bearings in grease - giving a poor/intermittent connection
The black from your battery -ve goes to a bolt on the frame. You need to check the resistance from the wire leaving the turn signal switch to this battery earth, with the switch pushed to left. You probably need the switch unit opened up to touch your multimeter probe on the bare wire. Resistance should be nearly zero. Check again at the wire entering the front flasher and the rear flasher. Anywhere the resistance is high tells you which area has a bad earth or a broken connection. I really would like to see you fix this but you will only solve the issue or issues with hands on the bike and thinking it through logically. You will never solve it by rushing out and buying something. IMHO.
