Well here's one I'm not sure how fix, my camaro has 406 with a CS-130 alternator that puts out 140amps and I use a Summit all-in-one distributor with a cannister style coil. I have an in line tach filter for the earlier factory tachs in GM's and I do run a Petronix rev limiter along with a Proform tach shift lite and my factory tach. Here's my problem, when I am driving and have my headlights on and the dual electric fans are running and I am at idle, say at a light waiting to turn, and my I activate my turn signal, my tach and shift lite flash with the flash of the turn signal, the voltage is good at 13.5-14.0 volts with everything running but I am getting interference from my turn signal but only at idle, any ideas? I am out of ideas and frankly don't know where to turn, pun intended, to go from this point. I din't have these type of issues when I was running the HEI distributor and I am not going back to that since what I have now works really good without any issues other than this and I don't know if there is another filter I should be using and where to put in harness for the tach, shift lite. Thanks for any help anyone can give me.
