About eight years ago, I installed
this turn signal switch on my '47. It has worked flawlessly during that time frame. Yesterday, on a 250 mile cruise a friend asked me why I use the four-way flashers as turn signals. Of course I don't and we investigated a little further and found that when I signal left or right, the both front turn signal lamps are flashing. Also, when I signal left or right, only the appropriate rear turn signal flashes. The four-way switch activates all four lamps and they all flash correctly. All connections are soldered and then covered with shrink tubing. The grounds at all signal lights and the switch were tested and have continuity. When the turn signal is activated, both front turn signals appear to be fully lit and not dimly lit like it's back feeding the circuit.
I'm not overly impressed with the quality of this switch and suspect that it's got an internal failure. If that's the case, is there a better after market seven-wire turn signal switch available? Has anyone experienced this condition/problem? I may open the switch and see what's going on in there........
Thanks,
