Charging System

The output from the generator positive main output 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. There are 2 similar cables of lower rating that 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 positive main output terminal and a ground stud on the rear of the generator. A 3-pin connector is on the rear of the generator supplies ignition voltage to the regulator through terminal No. 2 and output to the charge warning lamp through terminal No. 3. Terminal No. 1 is not used. See Fig 1 .
