Test battery voltage when car is running. Should be between 13 and 15 volts. If not, pull alternator and have it bench tested....if it passes on the bench test but fails the voltage regulator test on the vehicle, I would look at the wiring, one of the wires coming from the connector should be making it's way back to the positive in to the alternator....my 97 expedition happened to have that one connected to ground instead....

There is no such thing as a 4.5 motor. it is a 4.6. This car uses a G4 alternator which is controlled by the computer. If the rebuilder put the wrong regulator in it that may be the problem. You probably need to get a proper alternator.

Actually there is a 4.5 liter engine, but it's used on a boat....its the mercury mercruiser 4.5l
