I have an o5 mazda 6 2.3 atx, I replaced alternator a few weeks ago and now the batt light flashes on and off and if i am in traffic stop and go the abs tcs and batt light will stay on, head lights will dim wont shift out of third gear, and eventually die. But if i am cruising the interstate it does fine. anybody have any ideas? I removed the new alternator to have it tested it was fine. any help would be great thanks
