What the... what is up with my tach needle?
Okay guys, I'll admit I haven't searched, but I need a quick response here...
This weekend I drove my LS400 about 200 miles, and about 100 miles into it, I parked the car and when I started it back up, the tach needle just sat at 0 rpm's. Now when the car is off, the needle sits wayyy below the 0-rpm mark, and even at wide open throttle, it refuses to move above the 1000-rpm mark.
I have not messed with the cluster since I bought the car, but from what I was told, the last owner spent like $400+ getting it rebuilt, and whoever did it had done a damn fine job.
Anyways, what am I to do? What do I have to replace to fix this? Can I repair it? And most importantly, will it be cost-effective to replace it, or just live life without a working tach?

I'll check, but I don't think it's the tachometer-signal that's causing this, I think it might be a mechanical error in the cluster... just because when the car is turned off, the needle drops way below the normal resting point.

I had this on mine , it was showing a 300 RPM idle when it was really about 700 and wouldn't rev past 2500 actually showing when it was doing over 5000 RPM .
It was simply the needle loose on it's post , I simply pulled the dash out , took the front off and pushed the needle back onto it's post/stem in the correct position , haven't had a prob with it since .
