The post about buzzers brought to mind a problem I have with my aftermarket turn signal on the 52, when first installed the light in the handle of the switch would come on one time, that has since stopped and although I have cleaned ground spost of the steering column,cleaned all grounds and installed a ground from frame to ground cable cannot get the light to work as it is supposed to. I have checked the bulb it is good, I have replaced it with a new 6V that is a little to large but does not work any better. Any suggestions. I purchased the unit from the "Filling Station" several years ago. I am just now getting around to nit picking things.
