Shakadula Posted March 4, 2002 Share Posted March 4, 2002 because it is disconnected. I found the brown wire that I believe connects to the coil but am not sure where to connect it. Chances are the tach won't work once I connect it but I have to try that first. The service manual doesn't have much info on this, especially for someone mechanically declined as me. <P>Any help would be appreciated. Link to comment Share on other sites More sharing options...
rocketraider Posted March 4, 2002 Share Posted March 4, 2002 The brown wire connects to the coil (-) post. There's also a fuse inside the case on these 60s GM tachs. Link to comment Share on other sites More sharing options...

Shakadula Posted April 29, 2015 Author Share Posted April 29, 2015 So it has been years on and off and this tach does not work. Any thoughts on using the parts from a newer working tach and using my old dial face to have the advantage of new electronics with the stock appearance? This must be what the restoration guys do for 400.00. I can't spend that much. Hope I explained this well. Link to comment Share on other sites More sharing options...
JohnD1956 Posted April 29, 2015 Share Posted April 29, 2015 The tach should be a pretty simple unit. Before going to a lot of trouble retrofitting a new Tach, why not see if there is an electronics repair shop in your area and make an inquiry if they will look at the unit? Chances are there is a coil inside and the coil wire has broken. Could be a simple solder job will fix it. Link to comment Share on other sites More sharing options...
