Tach issue
My autometer tach was doing just fine, clipped brown and orange, tied into #10 White on the red connector. Out of the blue tach went haywire. Checked all wiring and connections and everything looks good. Replaced tach, still getting double signal, 3k rpm when it should be 1500 rpm. Quadruple checked every wire for nicks and bad connections, I have nothing. I'm lost, any idea's?
