My voltage regulator started acting up while driving... Would go from over charging to normal to discharging randomly... So I bought ECH VR56 from NAPA...

I charged the battery overnight... Installed the regulator and polarized it per instructions... Started engine ok... The ammeter read well into the charging side... Turned lights on bright and heater fan on high ammeter went down to almost the middle ... Voltage on the Battery and Ammeter side if the regulator showed almost 9 volts with engine running, almost 7 volts engine off, Field shows 3.5 volts of so engine running...

The Air Gap is .20" as it should be... The Air Gap on the other two out of the box is .035" - .040" ... I could not find the specifications for this regulator on the NAPA or Echlin website... Will setting them at the specifications of .075" - .085" bring it back to a more normal reading ?
