Hi all.
(sorry for my bad english) just got myself a Dodge Avenger, Everything (accept the airbag light) seemed to work fine. But after a half an hour drive, the avenger starts to do strange things. All the electric falls out ( windows -radio - blower - AC ect ect its all down). And it turns on again and falls out again..the dashboard starts to bring up the security light en flashes the tire masure light. The battery seems ok 12.5 , and the alternator gives een voltage of 14.5 I guess thats fine as well? Does anyone recognize this probleem?

p.s. No error codes on the OBD2 scanner
