electrical problem...HELP!!

[panhandlebronco]

when i turn the tail lights on the left hand turn single indicator light comes on, but if you turn the left single on it blinks as it should, where could the power feed back be coming from?

You have a ground problem on the left side.Check your running lights to see which one is dim.
