Every car ever made has a voltage regulator

The alternator is just that-- AC Current that is rectified
to DC-- to run the car & charge the battery

Just about every car for the last 40 years has the
regulator inside the alt

How it is controlled varies from manufacture,make,

You can not charge a defective battery

You may have external issues that provide
regulator control,even a bad ignition sw on
some cars,or module control of regulator

Need a wiring diagram & a good amount of
knowledge to resolve your current problem

look for a fusible link out. You need to check for output on the alternator that you installed. make sure the batteries are fully charged before that, otherwise its not going to read right. start from the source. also, you can disconnect the batteries from the sys and do a continuity check on the wires in the loom, so you can see if current has a path, or if you have an open circuit. hope this helps

Jump terminals A to F and the alternator should full field and charge. If it charges then replace the regulator. if it doesn't charge replace the alternator. I remember the terminals by thinking of the word AIR FORCE .

Battery light on

is the alternator charging? check a single tiny cable plug going to the alternator if it is not plugged right it could make the battery light flicker or simple turn it on. that little wire receives a signal from voltage regulator if alternator isnt charging correctly.

1988 ford taurus battery problem

regulator is built in to alternator, you need to have it tested. My guess is it's time for a replacement. Most parts places like autozone, will test it for you & sell you the proper one to replace it.
