My son bought a 2000 Lincoln. It has the familiar problem (I'm told) of oil leaks around the ignition coils and then subsequent failure of some of those coils. He plans to replace all the oil seals associated with this but first we cleaned all the coils and I checked them on the bench with an ohm meter and they all look the same. I realize of course that this is not conclusive though. These read like a standard three terminal autotransformer type of device, so can I assume that they function basically like a standard ignition coil? Can I apply 12V across the primary momentarily to induce the secondary field? I have a motor driven inturrupter of sorts that would accomplish this. I read about a procedure on line apparently utilizing special Ford test equipment, (WDC COP) and it shows oscilloscope waveforms associated with the coils firing during test. It doesn't show a procedure or connection diagrams though. I contacted the manufacturer of the test equipment, Teradyne, but all they would tell me is that it is Ford test equipment and that the equipment as well as the procedures are proprietory. I would like to perform a similar test using my own scope. Has anyone done anything like this? I would imagine that you could use an inductive pickup similar to the type found on a timing light placed around the secondary lead. I could wind a coil if need be. Does anyone know if this would be a viable procedure, and if so the details of the coil? Thanks, Lenny
