Tach help. Sticking and INOP.
My AutoMeter tach has stopped functioning. The needle stays around 1,000, power on & off. With the engine running, it does not move, unless I goose it, then it ratchets up, and ratchets back down. Checked the wiring, checked to make sure everything was hooked up (even though it has worked fine for some time now). I removed and reinstalled and still the same thing. What could it be (the big question)? Actually, has anyone ever run into this before? Should I just buy another tach?
