My MSD switch just started acting up today. When it activates my V-tec it starts making a funny electical noise. The light I have wired up when it activates v-tec is lighting up and v-tec is working it just makes an awful noise you know the funny electical noise. Is the switch fubared because it just started doing it. I did change the pills and it still does it. It doesn't make the noise til it activates. This is a D16Z6 swap in a 90 STD with a 88 Teg ECU.

 

I think problem is solved. While on lunch I noticed that the noise is coming from the 30 amp relay. I felt it to make sure and that is the cause of the noise. Its doing it only when the MSD turns on and off not while its working/not working. Going to Radio Shack tonight and get a new one.
Thanks,
Randy
