A new-to-me car with MSD and Chrysler electronic distributor. Supposedly they mounted a MSD adaptor to get the factory tach working before shipping the car to me. Well, the tach is active - bounces back and forth between 5 and 6 thousand steadily. I don't see an adaptor up front near the MSD ignition box where I sort of expected it. Is there someplace else likely where I should look? Under the dash? Is the factory tach typically just dead without the MSD adaptor? Or are the bouncing between 5 and 6 thousand typical of needing an adaptor with the electronic ignition (I'm doubting it)?
I'll call the dealer tomorrow to see what their service tech says.
