Description
4GWB
The 4G white with blue voltage regulator kit is used in many of Ford’s late model applications. The on board computer controls the output voltage of the regulator. Sometimes the decision is made for short periods of abnormally low voltage (12.5-13.5VDC). This would be considered normal. Unfortunately, many 4GWB’s are mounted in a labor intensive location. When you put a 4GWB kit on your vehicle, you should never allow a battery over 4 years of age to be used in the system. As the battery goes through a failure period, you may never know by starter draw abnormality. However, the computer controlled voltage regulator will suffer drastically depreciated life expectancy as a battery goes bad.
You know you have a 4G by the black metal cover on the back of the alternator as shown in pics 2 and 3.
Kit includes : High quality voltage regulator, new rotor, DE bearing, rear bearing with tolerance rings.
