Loose tightening of accumulator
terminals or oxidation of wire tags
Strip the wire tags and tighten the terminals
AB discharged below the permissi-
ble limit
Charge or replace the AB
Manifold and brushes are dirty
Clean the manifold and brushes
Poor contact between brushes and
manifold. Brush wear exceeds the
permissible norm
Take the starter off the engine, clean the manifold,
eliminate brushes’ sticking or replace them if they are
worn out
In the starter relay, surfaces of con-
tact bolts and contact plate that get
in contact during engagement, have
burnt
Clean the contacts of starter relay or set the contact
bolts in cover seats by turning around the axis by
180°, and reset the contact plate with the other side
Starter drive is out of order

After engine start, the starter remains in engaged condition
Contact plate has welded to contact
bolts of starter relay
Stop the engine, disengage the battery, then strip the
contacts of starter relay or set the contact bolts in
