An ACDelco Professional, premium aftermarket Voltage Regulator is the high quality replacement ideal for many vehicles on the road today. It monitors the proper voltage to your vehicle's critical systems as the starting and charging system starts the engine, maintains the battery's charge, and provides power to the electrical accessories while the engine is running. An ACDelco Professional Voltage Regulator provides outstanding radio noise control for better performance, delivers needed system voltage, and provides the proper fit and function to let your vehicle run the way it was designed. This premium aftermarket replacement voltage regulator is manufactured to meet your expectations for fit, form, and function. Review: Works perfectly Review: It works well enough. I'm using it to replace a broken regulator in the engine computer. With that in mind, the voltage does tend to fluctuate a decent amount with this regulator, especially under heavy load. The voltage gauge will actually wiggle back and forth when the turn signal is on. Otherwise, i've had no issues with this regualtor, you just have to make sure it has a really good ground on the case or you run a high risk of frying it.
