Procedure for troubleshooting

In the event of a closed-circuit current fault, use the following procedure:

• To isolate the originator, take readings with the current clamp on the supply leads to the front and rear power distribution boxes and, if necessary, on the supply lead from the safety battery terminal. In that way it is possible to determine the area in which the originator is located.
• The initiator can be determined by unplugging fuses one after the other at the corresponding power distribution box. As Terminal 30g is switched off 30 min or 60 min after Terminal R off, troubleshooting must focus on the components supplied by Terminal 30 and Terminal 30g-f.
