Certain turn switches have to be grounded and may not say so [signalstat]. Also, its hard to find a good quality 6v flasher, you may very well go thru a few before finding a good one. Lights lighting but not flashing or flashing erratically is a symptom of a faulty flasher. If the switch is a signalstat, many times it needs to come apart and most of the contact terminal grease removed.
