Bouncy Tach

Hey guys!

I went to start my truck today, but it didn't have a good enough of a ground to crank the engine over, I moved the ground and the truck started, but since then, my tach has been bouncing sometimes. When it first started, it was swinging all over the place, but on my way home now, it was just quivering every once in a while. Is this a problem with the tach itself or the dizzy? The truck runs flawlessly otherwise...

Aftermarket or factory tach?

Factory BTW I've gotta do my exhaust up a bit better (that bailing wire didn't hold, Steve, lol, thankfully they both just dropped real close to the ground and are sitting on my axle, don't drag, woo!) and change a U-Joint, so I'll check my grounds tonight. Only thing that is a bit odd, it bounces towards the 5000 rpm mark rather than 0, and if you unplug the input wire, it goes down past 0... Which is why I figured that maybe my problem was related to the dizzy. I'll check it's wire, and check the grounds...
