I broke my tach!

[cruzincivic]

Hey i somehow broke my tach because it will no longer go past 3k. I tried to install a voltmeter in one of my gaugepods and connected the positive wire to my positive tach screw in the cluster. The meter worked but the tach did not want to go past 3k. It would jump when i reved higer than that but go back down when the rpms came down. I just took out the meter and it still does it.

Any help appreciated!
