I was out for a minute to-day when I came home and shut the car off I noticed the tach was stuck at around 3800. I started it up a few times but to no avail, it just stays at 3800. Jeez, it was working perfect, any ideas? Its a Auto-Meter monster tach with 4 wires, red,green,white and purple. I asume green is ground, and red is hot. The light works on it so it has power from the ignition switch. Thanks in advance, as I said before I know I'll have lots of questions about this new ride, 86 Chrysler Laser with a 360.

Doc here,

Is the lamp and power the same wire (tied together?), If so check the Tach ground, If that is good then check the wire going to the Dizzy, be sure it didn't fall off, or break along the way.

Those tach will tend to hold the last reported position when power or signal is lost to them. So that's an indicator one of the wires has come loose.

Also if the connections are good, It may be time to replace it..you can check it on another car, before you toss it, if it won't respond there, it's bad..

Thanks Doc for the answers on both tach and horn and all the others who replied. As I have no garage now and the weather has turned lousy, I'll get at both 1st chance I get.
