Generator ground cable to voltage regulator

For Ford GPW

Ground cable that provides the connection between the generator and the voltage regulator housing. A proper ground connection is crucial for correct operation of the 6V charging system. This cable provides the return path for the field circuit formed in the regulator.

Application

Generator - voltage regulator

Voltage

6V system

Vehicle

Ford GPW

Type

Ground cable (ground wire)

Features

  • Connects generator to voltage regulator housing
  • Essential for proper charging system operation
  • Provides return path for field circuit
  • Fitted with correct terminal eyelets
  • For 6V positive ground system

★ An often overlooked but essential component — without a proper ground connection, the generator will not charge.

Application

For Ford GPW with 6V Auto-Lite generator and VRY-4203 series voltage regulator. Fits generator types GEG-5001A, GEG-5002D and GEG-5101D. Production 1942-1945.

Installation notes

Mount the cable between the ground connection on the generator (marked 'G' or small screw terminal next to field and armature terminals) and the voltage regulator housing. Ensure clean, oxide-free contact surfaces for optimal conductivity. When replacing, first disconnect the battery and polarise the generator after installation.

Compatibility

ONLY for Ford GPW with original 6V positive ground system. NOT suitable for Willys MB — MB uses on some versions a woven sheath around the other cables instead of a separate ground cable. Not compatible with 12V conversions or negative ground systems without modification.

Historical context

Ford GPW jeeps used the Auto-Lite 6V positive ground system with Type A circuit from 1942 to 1945, where the field winding is internally connected to the armature brush and the ground connection is regulated via the regulator.
