HOT WIRE SAFETY DEVICE

The voltage is distributed in the electrical system using cables suitable for withstanding the current absorbed by the electrical devices. The cables are increased by safety coefficients, so that they are safe to use.

The safety devices with hot wires protect the car from possible overloads, which can damage the whole electrical system at the points where they are not protected in the conventional manner.

The term "hot wire" means those cables which connect the battery positive to the electrical device without the help of fuse protection; this is possible thanks to the special sheath which covers them.

Schematic diagram showing seven hot wire connections between the battery positive (1) and various components: starter motor (2), alternator (3), maxi fuse box (4), ABS fuse (5), air conditioning system fuse (6), radiator/condenser fan fuse (7), and preheating control unit (8).

There are seven hot wires on this car, and they involve the following components:

  • Connection between the battery positive (1) and starter motor (2).
  • Connection between starter motor (2) and alternator (3).
  • Connection between the battery positive (1) and maxi fuse box (4).
  • Connection between battery positive (1) and ABS fuse (5).
  • Connection between battery positive (1) and air conditioning system fuse (6).
  • Connection between battery positive (1) and fuse for radiator/condenser fan (7).
  • Connection between battery positive (1) and preheating control unit (8) (diesel versions).

This car is fitted with a protection system using a maxi fuse box (containing six fuses, of which three are optional depending on the version of car).

This system is different from the previous systems which used a single fuse, because it manages the various activities separately, so as to avoid seizure of the car if a fault occurs.

The fuses used are:

A. Fuel injection (30A; 60A for Diesel)
B. Ignition (40A)
C. Radiator fan (40A)
D. Fuse unit (80A)
E. Additional optional extra (60A)
F. Air conditioner (50A)
G. Antiskid (60A)
