Replaced factory cluster w aftermarket. Turn signal issues

Running a classic dash with Auto meter incandescent gauges and led indicators ( turn park brake and high beam ) I Daisy chained the grounds on everything I installed and ran a self tapping screw through a ring terminal to the steering column support. I have no issues and everything blinks / illuminates as it should.


I say all that to say 12V systems with ground issues can manifest themselves in a variety of erratic symptoms. Check your ground and make absolutely sure it's good.
