normal driving voltage is 14-15v when I change the gear in high RPM 3 or 4 times my voltage goes down around 12v. I think the alternator stops only the battery voltage stays. that time car using only battery voltage after the normal driving alternator suddenly coming back and voltage increasing to 14v again.

Hi everyone, I have 2006 350z (130000km) recently I have voltage problem When I make a hard acceleration,my alternator is failing down and stop working at the same time hand brake and battery lights on. 1 week ago I went to the Nissan service, technical service 4 days tried to find out what caused the failure. finally yesterday they called me and told me the name of the problematic part. The name of the broken part is Solenoid Valve. technical service said dysfunctional parts need to be replaced than I said ok, change it and they replaced to part, they put the new one and I took my car today, and I've tested but but nothing has changed everything is same I immediately called the person in charge and he said come back again I do not want to go there again What do you think causes the problem. Please help me guys They said alternator and battery working fine also all cables all connections are fine what else?? Thanks
