Power Circuits

WARNING: This page is about a different car, the 1995 Ford Aerostar. 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. Also check for battery voltage at terminals No. 37 and 57 (VPWR). If battery voltage is not present, power is not being supplied from EEC power relay. See CIRCUIT TEST B in TESTS W/CODES - EEC-IV (3.0L) article.
