JohnFain_29U_Plymouth Posted October 29, 2005 Share Posted October 29, 2005 On the Model A Ford ignition coil, I am told that a replacement coil has the terminals labeled + and -. The supplier states that when installing the replacement coil on a Model A, the coil should be mounted (and wired) so that the Positive terminal is on the passenger side. I have a small wiring diagram of a Model A, but it is not very detailed. It shows the passenger side coil terminal wire connecting to the instrument cluster, and the driver side coil terminal connecting to a terminal box. My question is, for this set up (for the Positive ground Model A Ford), which coil terminal is connected to the distributor points (+ or -), and which to the battery?

Guest JT Posted October 29, 2005 Share Posted October 29, 2005 On a positive ground car generally the + terminal of the coil goes to the points. Link to comment Share on other sites More sharing options...
