    VCM Wiring Harness for GM ''D'' and ''AD'' 4-Pin Series Alternators (1995 to 2008)
  • Harness Only; VCM not included

Since 14V batteries need to be charged at 16.8V, XS Power has introduced the all new Voltage Control Module (VCM) that simply plugs into the factory or aftermarket alternator to allow it to charge at the appropriate voltage for the 14V battery. The XSP310 VCM is designed to control one alternator at a time, but in some cases can be wired to control more.

Specifications:

  • Operating voltage- 10~20 volts
  • 12V battery dip switch setting- 14.2 (varies depending on alternator) to 15.2 volts (programmed limit)
  • 14V & 16V battery dip switch setting - 14.2 (varies depending on alternator) to 19.5 volts (programmed limit)
