[DML] Wacky tach still

["ironranger7012" <kvlauhala@xxxxxxxxx>]

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
