Anyone know why my smart craft tachometer would be showing revs going up and down between about 2000 and 4500 rpm when the motor is running or even with only the ignition on ??

Please see the Forum Announcements, and provide the REQUIRED info. Thanks!
Will also help to know which Smartcraft Instrument you have (if unsure, post a picture).
