I have a 2002 Ford Taurus my car just stop charging I have bought new battery,new alternator it will charge for a good minute then stop someone said it could be my voltage regulator can't find it

SOURCE: i have an 85 amc

you need to put a chevy alternator with a built in regulator on it.
You need a 3 wire alternator. Two wires go to the battery and one wire goes to anything connected to the ignition switch.

SOURCE: replaced the battery and the alternator in 2006 ford taurus

check the alternator fuse and grounding

SOURCE: 1991 ford festiva replaced alternator new

it is part of the alternator actually on a lucas unit, a small black box bolted to the rear of the alternator.

You may have a faulty ignition switch or a corroded engine earth cable causing the alternator not to reach charging voltage.

Doesn't have an external regulator, If battery is reasonably fully charged it doesn't need 25A + of a charge . Put on your rear window de-mister and headlights and check voltage before and during test !
Good Luck

I would check fuses and relays first..Check the voltage coming off the alternator on the big red wire,,instead of across the battery..Some cars still use a fusible link..You would no that if you have charging voltage at your alternator but not at the battery..Should be 14.0 volts or close to it..with no load
