I just got my '52 Mercury back from a tune up a few weeks ago and I just love driving it now. I have a concern though. My overdrive has been acting up (at least I think so). It seemed to work again today…
To see if it is actually engaging and slowing the motor I thought I could install a tach to help me out.
What kind of tach would you need for this car and how would you go about installing it?
