1967 Camaro Factory Tach Not Working Properly
« on: October 06, 2013, 10:58:23 PM »
Hello everyone- I am having trouble with my tach. It works, but it is giving a high reading and when I give it gas it really jumps high. I put an analog tach to it at the same time. The analog reads 800 and the factory tach reads 1500. I recently had it services at Redline- good guy. It seemed to work initially but went erratic again. I have done the following:

Confirmed i have power to cluster- all lights work, blinkers, etc.
Changed the coil
Took each screw out of the housing cleaned and put back

When the tach broke the first time, he indicated the ground wire in the back of the tach came loose. He fixed it and it seems still connected. Am i missing something. Is there another ground i am not aware of?

Thank you. I appreciate the help.

Jerry
