Relay-regulator VALEO
If the length of the brushes is 5 mm or less, replace the brushes. To do this, unsolder the cores of the connecting wires.
Check slip rings for wear, finely grind and polish if necessary.
Clean the contact surfaces, check the tension of the contact springs, replace the springs if necessary.
Installation
Insert the brushes -A- and springs -B- into the brush holder -C- and solder the connecting wires.
So that when soldering a new brush, the solder does not rise along the core to be soldered, it must be covered with tweezers.
Caution: As the solder spreads through the strand, it would become hard and the brush would become unusable.
The insulating sleeve of the core must be fixed next to the soldering point with the existing lug.
After installing new brushes, check the ease of their movement in the brush holder.
First fasten the relay-regulator by hand with one screw, then carefully press it into the final position and tighten both screws.
Connect the battery ground wire.
