Alternator Repair

Pina ayos ko today yung alternator ng crosswind namin.. since hindi nag ccharge at dndrain yung battery nung kotse.
sabi nung mekaniko kelangan daw irewind yung coil at palitan yung IC. tapos yung carbon brush hindi na pantay eh okay lang ba yun?

anyway sabi niya 6pm today pa namin makukuha ulit yung kotse.. kasi iniwan lang namin sa shop nila para daw matesting nila mmya..
3k yung singil lahat na..
