I agree that the poor grounds will can cause strange behavior but I chased poor grounds for weeks before I found the LED flasher in my truck with all incandescent bulbs. The flasher is cheep and easy to change. It may not be the problem but you need to match LED flashers to LED bulbs and vice versa. Logically that is the place to start.
