Voltage Regulator for Specific T25 1981–1992 T4 1990–1996

This important component 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. It's well worth replacing if you are in any doubt as to its condition.
