How do you wire a Dodge alternator?

On a dodge alternator the two small wires go to the voltage regulator . It doesn't matter which wire goes where, but the red or blue wire needs 12 volts when the key is on. The green wire goes directly to the regulator from the alternator. The large wire goes to the battery and it is important that you don't undersize this wire. The other wire is a ground wire and can be grounded to the block or not used as the case is grounded by the bolts that hold it on.


Does the battery light being on mean the alternator is bad?

Not all the time. The alternator warning circuit wiring to the instrument panel could be grounded


Where is the alternator grounded on 1997 Ford Taurus?

Alternators are generally grounded through the alternator body to the engine block or head through the attaching bolts.On many cars I've owned I add a ground strap from the alternator body to the block to eliminate any chance of poor connections throught the mounting bracket.


What could be wrong if you have replaced your battery alternator belt alternator and alternator wiring harness on your 1999 Intrigue and your battery light STILL comes on?

you have a short where negative is touching the metal of the car or it is grounded inproperly


Why is your radiator fans not working after you had an alternator put on at the garage?

Radiator Fan Doesn't Operate After Alternator ReplacementI suspect that the wiring harness to the Radiator Fan got disturbed inadvertently during the Alternator replacement.This could include a connector plug being pulled loose, a wire cut or broken or "pinched" and thus in contact [grounded] with/to a component of the engine which is grounded.


Where is the grounded wire to the starter alternator to a 1087 silverado truck that will not start?

the starter,battery and the alternator are good,icheck and change the the wires but the light inside the dashboard,the headlights come on but the truck will not start.


Why would the alternator light be on if the alternator is working this is on a 1985 Chevrolet truck?

The alternator light circuit is different from the charging part. The charging part goes to the battery, while the light part goes to the instrument panel. There seems to be a grounded wire in the light circuit.


How are alternators linked to the cars battery?

The output lead from your alternator is bolted to the positive lead of the battery at the starter solenoid. The grounds are both to the vehicle body or, in some cars, the ground from the battery is grounded on the alternator bracket.


Your 1998 sidekick keeps turning off has new alternator and batterie what is wronge?

have you considered checking or changing the following: 1. Maybe the connection of the battery terminal is grounded 2. Maybe the connection in the alternator is grounded 3. check the fuses inside the fuse box and the fuses near the battery 4. how about the sparkplugs have you checked it I hope this helps


What does an isolated ground mean on a 12 volt alternator?

This might mean the ground is isolated from the case of the alternator. In a normal application, the case of the alternator is the ground connection and being bolted to the engine block via a metal bracket, the grounded case of the alternator is electrically connected to the ground lead of the battery which is also connected to the engine block. An isolated ground might indicate the alternator ground is electrically insulated from the alternator case.


What does a stator do on an alternator?

The stator on an alternator is used to generate a magnetic field. This is a large factor in the production of electricity.


Why neutral of generator is resistance grounded and neutral of motor is reactance grounded?

You can use resistance or reactance grounding on generators and motors. My understanding is resistance grounding is often used to limit ground fault currents to a few amperes, while reactance grounding will limit fault current to less than the three phase fault current. If reactance grounding is used to limit fault current o very little (like resistance grounding), transient overvoltage problems can occur.
