Jumpy Tach

TheMeaningOfLife · 08-31-2007, 12:18 PM

I changed out the bulbs in my gauges with the LEDs and everything worked perfect, kinda. Theni was driving and noticed that the tach is kinda like jumpy rather than smooth. It did it before and i unplugged it and re plugged it in and it when away. Not his time though so what did i do wrong?

That's really weird. I'm not sure how the Alero cluster is (never took one apart) but I know in some older cars there's a cable that gets loose. One thing you may want to check is where you wired the LEDs up to and if they're causing a voltage drop. If the cluster isn't getting the proper amount of voltage or enough current it's possible for it to malfunction.

Im bringing this one back because iots doing it again. And two of my lights in my dash stopped working, i know there wired right because when i swap them out with a differnt spot they light up but the one back in the old spot wont light. Any idea? did i screw up my cluster?
