Removal
Remove the ground cable from the battery.
Attention
- When the battery terminals are disconnected, the memory units of the control units erase the data on the recorded faults, so before disconnecting the battery terminals, it is advisable to contact a specialized workshop to recall the faults recorded in the memory. After connecting the battery terminal, it is necessary to activate and reprogram the electric windows, as well as the position of the rear-view mirrors and seats.
- Also, if the car has a radio receiver with a code, before disconnecting the terminals from the battery, check that you have the code to reactivate the receiver. Otherwise, the radio receiver can only be put into operation at a specialized station.

Replace brushes if their length is less than 5 mm.
To replace carbon brushes, unsolder the current leads, remove worn brushes and springs.
Check the condition of the contact rings and polish them if necessary.
Check the spring pre-compression force and replace if necessary.
Installation
Install new brushes A (fig. 14.21) with springs B into the regulator socket and solder the current leads. When soldering, do not allow flux or solder to get on the current lead, except for the soldering point. If solder gets on the current leads, it becomes hard and the brushes will be unsuitable for use.

Check that the brushes move easily in the holder.
Carefully install the voltage regulator with brushes and secure it with screws, tightening them to a torque of 2 Nm.
Install the generator protective cover and secure it with screws, tightening them to a torque of 1 Nm.
