Don,
I agree with Tom, the needle may be "off".
I just got a TC tacko that read 5500 sitting still. Removed the needle, set
it at approx zero, and the tacko now reads accurately at 2400 RPM when I use
my 1200 rpm drill to drive it counter-clockwise ( tacko is 2/1 faster than
input cable ) .

On the tach, you may need to remove the cable, stick a small screwdriver in
the slot and dial it backwards. The pointer generally snaps right back to
zero. If not, you have a problem. The pointer could actually be "off", too.
