SOURCE: alternator light on

The alternator is not producing any power . If it were the engine would run without the battery. Check the wiring on the alternator. It must ave an exciter wire to make it work.

Faulty voltage regulator


You can look it up online at one of the auto parts websites, or check with your local store. The voltage regulator mounts on the back of the alternator, but it costs more than a rebuilt alternator does.

Cant find the voltage regulator anywhere? Can you please help. 1991 b350 van dodge


not like the old days it does not have an external regulator-it is integral with the alternator now, use a digital voltage meter to read the output at the rear of the alternator (large post)-is should be about 14.2 volts.

I would like to ajust voltage regulator but cant find it


Pretty sure the voltage regulator is INSIDE the alternator, and you CANNOT adjust it.
If it is putting out TOO much voltage, you could tear down the alternator and repair it, but it is easier to just put a re-manufactured one on it.

Your output voltage from the alt. should be between 13.75 to 14.75. If not, or if it 'jumps' alot, then replace the alternator.
test the battery voltage with a voltmeter with the engine off, then with it on. Battery should test 12 V. + if it is fully charged.

I have a 96 ford explorer I just replaced the battery and the alternator in it. When starrted the battery lite stays on and the alternator does not charge it. Is there a linkable fuse or something I am...


Trace all of the wires that are attached to the alternator. If there is a fusible link or a broken wire you will find it. If the alternator is charging but something else is wrong the alternator will pull a steel wrench toward it. You did not mention the voltage regulator. You will find it when tracing your wires. Look it over carefully. Voltage regulators fail keeping the alternator from working. Parts stores have regulators and they are easy to install.

Would the voltage regulator prevent my passat from starting?


it shouldn't. the voltage regulator is located either internally on the alternator or on the outside of the alternator. it controls how much voltage is delivered from the alternator to the battery, 12-14 at idle and up to 16 ish when revving. i have never heard of a voltage regulator preventing a vehicle from starting unless the voltage regulator malfunctioned and the car got something like 20Volts. then maybe that would have an effect...
hope that helps...sort of....dead batteries also prevent vehicles from starting.....something to look at i guess

low voltage pulling by what your saying it sounds like your alternator is about to give up seeing that it cant disperse elec. to other units so its draining off the battery

change out the voltage regulator they didnt change your alternator they just rebuilt it or did nothing it sounds like

voltage regulator = adjusts the voltage
some are built on the alternator and is replaced at once with new alternator
others look like a little fin like an amp usually black in color this you will see bolted on the fender right or left this is a voltage regulator

somtimes you get a bad alternator in box when it can be new this is a chance chance cause now most parts are remand.
i still believe its your alternator you either of several things
got ripped off
got a bad alternator in replacement or
you got a bad voltage regulator by itself
looks like this
