Tach not working.

[BC69]

My car has an aftermarket covans dash insert, and autometer gauges. Lately the tach hasnt been working. All the other gauges are working just fine but the tach isnt budging. I think at one point when I turned the car on it would move over to the 0, but for the most part it remained 90 degrees down and nothing. I thought it might be a fuse, but all the other gauges are working. A little work had just been done recently on the transmission and starter, could anything have been knocked loose? Any ideas...another one of those simple problems that I havnt yet found the simple solution to.

Thanks Again

check the wire to the distributor. it should be green

What ignition are your running? Stock, or an MSD?...MSD has it's own tach output, possibly loose, or perhaps someone forgot to replace the wire to the coil if you are running a stock type?

Its stock, There might be a lose wire there, that be an idea.

thanks guys.

Hey I am just bringing this back up cause I havn't solved this problem. I traced the wire to the distributor and tightened it, nothing...moved it around a few different times, and got nothing.
I have replaced some of the fuses, only one was really burnt out, but just tried anyway. Everything works fine except the tach and the gauge lights that come around each one...I dont get it. Is there a fuse connection in one of the wires?

Again, these are autometer gauges in the covans dash.

Thanks

Can you describe how you have it wired in? It may be as simple as a bad connection to the red wire, or a bad ground. How do the connectors look? How does the rest of the stock harness look? Is the connection at the back of the tach good? How about at the connector for the stock to Covan's harness? It could be a lot of things, including a dead tach.

I say bad ground...
