What is EEC power relay?
What is EEC power relay?
The EEC Power Relay not only supplies battery voltage to the fuel injection computer (also known as the E.E.C. Electronic Control Assembly), but also supplies power to the fuel injectors, the fuel pump relay, and a few other emissions related solenoids. stands for, it’s: Electronic Engine Control.
Where does the power come from on a Ford EEC relay?
This voltage comes from the ignition switch. Power (in the form of 10 to 12 Volts) is always present in circuit 4 . This voltage comes directly from the battery positive terminal across a fusible link on the starter motor solenoid (on the fender). Ground is always present on circuit 1.
What kind of fuse box does a 1998 Ford F-150 have?
The 1998 Ford F-150 has 2 different fuse boxes: Park Lamp Relay, Headlamp Relay, Autolamp Module Remote Anti-Theft Personality (RAP) Module, Power Mirror Switch
What is the low current circuit on a Ford EEC?
Every Ford EEC Power Relay has two basic circuits and for the purpose of our discussion, we’ll call them: A low current circuit. This circuit can be identified by the wires labeled with the numbers 1 and 2. The low current circuit is the control circuit that ‘closes’ or ‘opens’ the high current circuit.
Where does the voltage from the EEC relay come from?
This voltage comes directly from the battery positive terminal across a fusible link on the starter motor solenoid (on the fender). Ground is always present on circuit 1. As soon as the ignition switch powers up circuit number 2, the EEC Power Relay closes circuit 3 to circuit 4 .
