Alternators

An alternator is an old term for electric generator that converts mechanical energy to electrical energy producing alternating current. Alternators are mainly used for recharging batteries and to power electrical loads of vehicles.

What are two possible dangers when a wiring system has an unacceptably low value of insulation resistance?

Low insulation resistance causes power loss in that system. That's a direct loss. If you're paying for something like gasoline and it's leaking out the hose you use to get it into your vehicle, you don't get all you pay for. And then there's the distinct possibility that damage to the distribution system can result and further degradation of the conductor/insulator bundles can occur. The second thing could be a killer. There's always the possibility of a fire. That'd be bad.

Your if your Ford Fiesta 1800 diesel wont start its not the battery or starter motor or the alternator?

try squirting some sarter fluid in air filter .if this starts engine and then dies, try it again. if engine will run as long as you squirt starter fluid ,the stop when starter fluid runs out, pretty much means you are not getting fuel. so you then need to check fuel filter, fuel pump injectors and injector pump until you find the problem

How does an alternator produce different amps?

It depends on the load and the voltage. In an automobile, a battery will typically have a voltage of about 12 Volts. If the engine is not running and you turn on the lights, the lights will start drawing current from the battery and the voltage will drop by a volt or so, depending on how strong a charge the battery has.

An alternator will produce in the neighborhood of 15 Volts. If it is trying to push current into a system with a fully charged battery, it will only be able to push a few amps. If the voltage in the battery drops, the alternator will be able to push more amps. A completely dead battery will draw the most current (amps).

I had a weird noise when I was turning my car tightly and I could feel it My alternator just went and I just replaced it and oddly my car now turns fine Could a bad alternator cause that?

It probably isn't the alternator since it only happens when you turn the car tightly. Usually that would be caused by the steering hydraulic system due to a worn rack and pinion gear or power steering pump.

Why is there no power after replacing the alternator on a mitsubishi montero sport 2002?

Is the battery dead? Check for 12v on the main alternator cable. If no power, check for burned out fusible links between alternator and battery. You may need a wiring diagram to check further.

Why is your dodge stratus not charging a new alternator?

Cars don't charge alternators; alternators charge cars. If your new alternator isn't charging, it could be your battery is bad or your battery connections are corroded. Another thing it might be is your voltage regulator. Many alternators come with built-in voltage regulators, but if your system has a standalone v.r., it could be bad too. Finally, if your 'new' alternator is actually a refurbished or rebuilt one, it could be a bad rebuild. It happens.

There is not an alternator indicator light on a Honda Pilot. If the alternator goes out, the battery will not stay charged.
