Charging System: Description and Operation

The main components of the charging system are shown above.

The output from the generator 'B+' main terminal passes to the battery via the main terminal on the starter motor and then the power cable to the high power protection module located in the luggage compartment. From this module, a short main power cable supplies the battery positive terminal.

The return circuit is through the vehicle body and supplementary ground cables.

The high power protection module comprises four fuses, each rated at 250 Amps.

Battery output uses the same power cable as the charging circuit, to the high power protection module and to the starter motor main terminal. Two similar cables, but not such a high rating, supply battery power from the high power protection module to the fuse box in the luggage compartment and to the fuse boxes at the front of the vehicle.

The interference suppression module (where fitted) connects to the generator main terminal 'B+ and a ground stud on the rear face of the generator.

A multi-plug (3 pin) is connected to the rear of the generator.
Pin #1 not connected.
Pin #2 ignition supply to the regulator.
Pin #3 output to the charge warning lamp.
