Power and Ground Distribution: Description and Operation

A new electrical system has been introduced for 960,1995.
This has the following advantages:
- Increased reliability, as a result of fewer harnesses and more satisfactory connectors.
- Simpler access to relays and fuses.
- Better fusing of different components.
- Shorter signal/supply wiring.


Main fusebox: A
The main fusebox is located behind the battery. There are 8 fuses, each of 50 A. Because supply leads are fused directly from the battery, more or less everything on the car is fused.

This achieves protection for the wiring.

If, for example, the battery or the wiring is short-circuited and the main fuse blows, the wiring will not be exposed to high amperage which would otherwise result in the leads melting. The main fuses have allowed a reduction in the gauge of cables from the battery.


Relay and fusebox in the engine compartment: B




The relay and fusebox, next to the left wheelarch in the engine compartment, contains relays and fuses for a large number of functions In the engine compartment.

By having relays and fuses near their components, the number of leads hitherto running into the interior is reduced.

There is room in the box for 18 fuses and 13 relays.




To the rear of the box - see illustration - there is a foglight bridge (B/1) and a service point (B/2) to turn the starter motor.

Interior fusebox: C




The interior fusebox has space for 24 fuses and also two automatic fuses and three relays.

Two of these relays are bypass relays and the third is for the FP.

Relay box inside car: D
The relay box in the inside the car has relays, most of which are for interior functions.

There are some exceptions, however. For example, the intermittent operation relay for the rear window wiper on 5-door models is located next to the rear bulb failure sensor at the left wheel well.
