RPM gauge doesnt work
 

hey my rpm gauge doesnt work :( i moved the ignitor and put it all back together and then my rpm's dont work

When you say you moved the ignitor, where did you put it and what exactly did you do?

when i was trying to install msd i took out the trailing one on accident and then when i put it back together it rpm doesnt work

car idles/runs fine.

remember, your tachometer works using your trailing ignition. do you have an ignitor for the trailing side in place and working correctly?

Hmm, sounds like a loose connection. The trailing ignitor does control the tachometer. Make sure all the terminals are clean and free of corrosion and that the trailing ignitor is hooked up exactly as it should be. If that doesn't fix it, take a couple pictures of it and throw them up on here so we can see what your working with to better figure it out.

yeah i have another ignitor. and we hooked up the ignitor 2 different ways to see if we connected it wrong.
