How to Install a Voltage Regulator on a Chevy

Prior to 1973, all GM cars were equipped with alternators that did not have voltage regulators. The voltage regulators were bolted somewhere on the fenderwell or firewall, depending on the year and model Chevrolet. From 1973 through the present, all alternators have built in voltage regulators. If the voltage regulator on a newer vehicle malfunctions, you must replace the entire alternator.

Instructions

1

Disconnect the negative battery cable, using a wrench. Set it aside, ensuring that it does not touch metal.

2

Label the wires on the voltage regulator. Disconnect the wires, using the appropriate screwdriver or socket.

3

Remove the regulator's mounting screws. Depending on the year and model of your vehicle, and depending on whether the original bolts were lost over the years and replaced, you may need a Phillips screwdriver, common screwdriver or socket.

4

Bolt the new regulator in place. Ensure that the terminals on the wires are clean. Reinstall the wires in the appropriate places, as previously marked, and tighten the screws or bolts snugly. Reinstall the negative battery terminal.
