Default erratic tach Stewart Warner
My cobra has been on the road since1992. I had to replace the tach about 5yrs ago because it would be erratic, jumpy, and would often indicate twice the actual RPM's.
Now I'm having the same problem. I wonder if the MSD ^AL is causing a problem with the tach circuitry oor if I just got two bad tach's.The is a company , APT that supposedly repairs them and makes them more "friendly" with MSD units.
Any information would be appreciated.
Steve
