GE, All Lincoln Mark VIIs left the factory with a CHECK ENGINE socket and bulb. (Certain Fords and Mercurys are were you really gotta consult the shop manual) Your issue is IGNITION SWITCH related. Until you replace it, any tests you perform could give you false results. See http://www.thelincolnmarkviiclub.org/documents/tech/1984ignitionSwitch.pdf
