Red light on tach won't go out.
I'm not very tech savvy and I'm sure there is an easy answer to this...I have an Autometer racing style tach in my street rod. It came with the car when I purchased it. For some reason the red light (it has both a yellow shift light and red light) won't go off. It just came on recently and stayed lit. Is this just a function of adjusting the shift point dial or is it something more complicated? When I turn the ignition on the red light comes on and stays on. As I stated, it just started doing this. It went off once when I was driving then came back on and has stayed on since. Other than that, the tach works fine. Any ideas what to do to get it to stay off? Thanks!
