The fuse box, also known as CEB for central electrics box, is very vulnerable when high currents flow.

Often individual power consumers suddenly fail, usually these are large power consumers such as:

-Fuel pump

-Heater fan motor

-Headlights

The cause is often cold solder joints within the CEB.

Since the ZEB is soldered in two layers from 2 circuit boards, repairs are often very difficult and can only be carried out with a great deal of time.

A bypass is often the easiest way to avoid such interruptions. To do this, a circuit diagram is used to check exactly where the interruption is and then a bypass is created using a cable.

Such work should only be carried out by an experienced vehicle electrician. The risk of cable fires is very high if the work is carried out incorrectly.

​

Before considering the CEB as the source of the error, it should be carefully checked whether a relay, cable or fuse is simply defective.
