I have an autometer shift light, I was wondering if the fuse that controls when the llight goes on, ever goes bad? The reason I ask this is because last night when I was the light never came on.
It does come on when I first start the car like usual. Could it be the RPM fuse, or could it be a bad connection to the tach signal? I don't know how long its been like this it worked fine at the track a few weeks ago. I don't really get on it too much.
Any help would be appreciated.
