I have a 79 10 anniversary cb750. Turn signal not working. Won’t start with lights on for night.

Turn signal only work with ignition all the way to the right for night. But will only start with ignition in the middle.

I had the same on my -83. I charged the battery, and problem solved. Seems the relay could be sensitive to slightly low voltage. If the headlight and tail is turned on with your ignition in the middle position, the voltage may fall sufficiently for the turn-relay to stop working. (Assuming your engine is not running when testing turnlights. If running, check voltage i.e charging could be failing)
