[DML] Wacky tach still

[doctorDHD@xxxxxxx]

Vic,
 
Was your service tach connected very close to the actual in car  tach? 
 
Exactly where did you connect it?
 
Why is the tach lead to ground 25.5 ohms?  That doesn't seem right. It  shoul
d be zero or close to it.
 
Try to connect your service tach to the back of the instrument panel right  
where the actual in car tach connects and see what happens.
 
Run a separate ground wire (0 ohms!) from the tach to a good ground  point 
and recheck.
 
My CSS-100 connects to the tach wire...have you tried checking it with out  
the CSS wire cnnected?

Thanks all for  the possible cures but to no avail.  I checked and 
cleaned all of my  grounds with contact cleaner.  Took the dash out, 
cleaned all  connections likewise; took the tach out and cleaned the 
tach connections  under the nuts. Used my volt-ohmeter and checked 
continutity with all  conections on the tach. Put it all together and 
checked ALL connections.  Started the car up and put my service tach 
on and it read 775 rpm at idle.  The car tach read 1200 +/- 100rpm.  
Reved it up to 2500 on the  service tach and the car tach was reading 
4000 +/- 200 rpm. I checked  continuity from the coil to the tach 
connection in the dash. (.1 ohm)  Checked tach lead to ground (25.5 
ohms) Everything seems to be ok except  for the wacky tach.  Makes me 
wonder if this new one I bought and  have been putting up with is 
just a POS. 
This car is in very good  condition, all original, always maintained 
by me. I have the complete  history. I drive 2k - 3k a year. Always 
garaged.  When I heard others  having problems with grounds and 
connections I checked everything and all  mine look just like new. 
The only thing I've added is a CSS-100 cruise  control. 
Oh, by the way, I was over talking to Ryan Wright a week or so  ago 
and I recall someone talking about the front license plate.  I  have 
mine mounted just below the bumper ridge with a sst piano hinge so  
it allows air to flow into the radiator.
Again, thanks all

Thank  you,
