Repair And Fix it

Use a wrench to detach the cables from the battery. The battery is typically located under the hood, directly behind the grill of the automobile, on either the right or left side. It has two cables attached. Detach the positive cable first, it will be labeled with a "+" sign. Loosen the nut holding the cable by turning it counterclockwise. Remove the negative cable in the same way.

Locate the voltage regulator. It is either in a black plastic box on the back of your alternator, which will be labeled on the belt diagram under the hood of your car or in line in the battery cable between the alternator and the battery. Consult a repair manual for your make and model for more specifics.

Position the new regulator over the old for remote regulators, inline with the battery cable and not attached to the alternator and unplug each cable from the old regulator and plug it into the new regulator. There may be up to four cables, depending on the make and model. For cables attached with screws, loosen the screws by turning them counterclockwise with a screwdriver. Attach the cables by fitting them onto the corresponding screws on the new regulator. Tighten the screws with the screwdriver. For integrated regulators, those attached to the alternators, move directly to the next step.

Remove the wires from the broken regulator. Bind the end of the battery wire with electrical tape. This avoids any potential sparks that might occur if the wire rubs any metal parts. detach the regulator from the alternator by removing the adhering bolts or screws with the adjustable wrench or screwdriver.

Look at the bottom of the regulator for the two carbon brushes. Remove them and use the sandpaper to carefully clean the contact ends of the brushes. Apply electrical contact cleaner to the brushes, and insert them into the new regulator. Match the wear patterns on the brushes to the patterns on the new regulator. If the patterns do not match, the regulator will not work correctly.

Connect the new voltage regulator to the alternator carefully, making sure not to damage the brushes. Secure the regulator with the bolts or screws and attach the wires using the adjustable wrench or screwdriver, Reattach the ground cable to the battery and close the hood.

Start your car, and run it at 1,000 to 1,200 rpm. Look at the voltmeter on your dashboard to check the battery voltage. If voltage is not in the 13.5 to 14.5 range, read your regulator instructions on how to adjust the voltage. Recheck it after you make the adjustments.

Remove the power window control retainer screw from the window control and door lock switch housing, using a Phillips screwdriver.
