Car: Alfa Romeo 159
Salut colegi Alfisti
Recent am reconditionat un alternator auto(am schimat regulatoru de incarcare , punte de diode , rulmenti , colector toate noi special pt alternatoru respectiv ) demontat de pe masina personala Alfa Romeo 159

motivul pt care l-am reconditionat a fost ca nu mai incarca corect max 12 v

am montat totul inapoi pe masina , am pornit masina iar pe urma am verificat incarcarea care era de 14.1 V cu faza scurta si lunga pornita plus ventilatia la max

am mai masurat tensiunea la partea de excitatie a alternatorului care este de 12.9 v , acumulatoru este marca EXIDE 90A cumparat de nou de 3 saptamani (cel stoc era de 70 A)

problema este ca inca imi apare martorul de baterie in bord

am masurat rotorul iar rezistenta lui era de 3 ohmi iar infasurarile statorului aveau in jur de 0.6-0.7 ohmi intre ele , am mai verificat firele de masa dintre motor si caroserie dar nu am vazut nimic in neregula

Am tras un fir de la borna de plus la pinu ul de la excitatia alternatorului dar tensiuea de la bornele bateriei nu s-a schimbat

ce este de facut ?

multumesc frumos
