How to fix my lazy tach

[zephyr125]

My tach likes to jump around for a second or so before settling out after shifting. At first it was kind of quirky and I enjoyed it but now its getting more noticeable and annoying.

The one in my Touring does that too. It's real annoying once it catches your eye.

The one in my 73 does it as well. I cleaned everything up and put in a higher quality ground on the IP, but it didn't solve the problem. Maybe the issue is on the coil side?

I had the same problem on my 76. I tried all the connections and an aux ground at the console, still not working. Then I cleaned all the connections on the coil and used a pair of pliers to tighten up the connectors so they fit tighter. Problem solved. Forgot which wire was the correct one so I did them all.

I'll try this and report back, thanks!
