Voltage regulator for use with alternators that have an external regulator. Fits T4s from 1996 to 2003. Regulates the charging voltage produced by your vehicle’s alternator – maintaining it between 13.5v and 14.5v in order to run efficiently and to protect the electrical system. Too much voltage and costly damage could result with parts burned out; too little, and performance is weakened.
