Tachometer not working
A couple weeks ago, I pulled off the broken glass cover on the gauges to replace it with plexilglass. While I was doing that, I cleaned the face of the guagues and moved some of the needles while doing that. After I was all done I put the cover back on and started it up and the tach was sluggish and didnt read the exact rpm. I realize that I could have screwed up the calibration or something of the needle, and was wondering if I was completely screwed, or if i could fix it. Any advice on this would be helpful.Tags: None

The amount of spring preload makes a difference in the accuracy of the gauge. Sounds like you have too much preload. I'd pull the gauge apart again and try again with the needle replacement.Ed
To measure is to know.

Yes, before i pulled the glass off and replaced it, the needle worked flawlessly. Im thinking that with me cleaning the face of the gauges, I was moving the needles to clean underneath them and i think that moving the needles while it was off screwed something up. My friend told me that while he had his mustang gauges out, so i just assumed that it was no different on my bike. I did not remove the needles when i had it apart because I heard that then you have to re calibrate it and I didn't want to do that. Looks like that might be the only option at this point.Originally posted by rustybronco View PostWhat bike are you speaking of and did the tach work while the glass was broken?

This is pretty much the answer to your problem; pop the needle off and try a different position.Originally posted by Nessism View PostThe amount of spring preload makes a difference in the accuracy of the gauge.

When you get the tach so it's reading correctly, crimp the lens back on.
