Signs of a Bad Voltage Regulator

Voltage Regulator

Warning lights, unpredictable engine performance and dimming lights are all signs of a faulty voltage regulator. A number of symptoms can develop if the voltage regulator fails to deliver sufficient voltage. Warning lights may not inform the operator of such a failure until it is too late, so it is important to be aware of the associated issues.

Ignition systems, fuel pumps and computer controls all rely on sufficient power to function properly. Engine performs awesome if voltage drops. Voltage regulators also perform badly by generating too much power. You can check the charging systems when the tail lamps and headlight bulbs abruptly go bad. Heavy venting occurs when the battery receives too much power. This releases substantial acidic vapors, which corrode nearby surfaces. Look for signs of corrosion near the battery, but do not touch the battery if it emits a vapor or makes strange noises. If charging systems fail to illuminate, then you need to check the operation of the lights and warning indicators by turning on the ignition switch without starting the engine. The lights should come on and stay lit until the engine starts.
