Trying to hook up turn signals . Just bench testing now. Using a flasher that I had, the lights come on, but won't flash. I thought maybe bad flasher unit, so purchased a new flasher. With the new flasher the bulbs hardly even light up. You have to look real close to see that there is actually some light there and still no flash. Put old flasher in, and the lights are bright, but no flash. Do you think the new flasher is bad? I have everything grounded that I can think of. The turn signal switch is an old push button KD 723. Thanks for any help..I am only using the light assembly for turn signals, nothing else. 6 volt...52 Pickup..Thanks...
