| the tachometer is not working properly. The indicators shown by the tachometer are almost twice as large as the actual ones. What could be the problem? Caprice 9C1 1991 | |

| The circuit board on the back probably has a bad part on it. You can send it out for rebuild, or get a donor, and swap it. | |

| Any of the electronic components can fail. I can not troubleshoot through the computer. I do not know of any schematics for the cluster. | |
