I change the alternator for a new one . Put new plug with wire , but in night with headlamp , radio and AC on ,blinking the batterie light and the neddle volt raise out of the limit . Inmediately shutt off and wait fews minutes and start again . All is normal but repeat with many interval. Voltage regulator problem??
