Power Circuits
WARNING: This page is about a different car, the 1995 Lincoln Mark VIII. However, it is still accessible from the selected car via links, so may be relevant.
Using a voltmeter, check for battery voltage between PCM terminal No. 1 (KAPWR) and ground. See Fig 1. Check for battery voltage at terminals No. 37 and 57 (VPWR). If battery voltage is not present, EEC power relay is not supplying power. See CIRCUIT TEST B in the TESTS W/CODES - EEC-IV article.
