Re: tach issues
Bet someone with a bi directional scan tool and perform a gauge sweep. All the needles should move through the full range.
I would bet 99% that the gauge itself has quit. |

Re: tach issues
So I went to the yard. Found another cluster. Bought it. Then thought maybe I should check all the fuses. Found a blown fuse under the hood marked "gauge" ( there's 3 marked gauge) and viola!!! A working tach!
Anyone need a cluster in nice condition?
