Can a car still run if the alternator is dead?
Sorry to say,but no. The alternator is the device that replaces the power that has been used from your battery.Without the alternator, the battery will get drained and not be able to recharge.
Where is the voltage regulator located on a 1995 Mitsubishi montero located?
Modern alternators almost always have their voltage regulator attached to the back of the alternator itself.
Most often it is combined with the brush holder so you could say it's "built in", however that is not strictly true as it is removable without dissasembly of the entire alternator.
Unless I am mistaken the Montero alternator is of this design. You should NOT expect to find an external voltage regulator anywhere on one of these vehicles.
Hope this helped.
How do you replace the alternator on a 1998 Jeep Grand Cherokee?
the alternator is on top of the engine start by takin off the fan belt and then removing the wires conected to the alternator finally unbold the bolts holding it on and then take it off
It could be the voltage regulator.
He said that there was no question that leaving a battery sitting on concrete will eventually ruin it. I asked if it had something to do with the "heat sink" effect of the concrete and he said no, that temperature had nothing to do with it. Here is how he explained the phenomenon which damages the battery.
Although the rubber or plastic battery case is liquid tight, and the liquid cannot penetrate it, components of the electrolyte molecules CAN migrate through the case, and penetrate into the concrete. Then, changes in the concrete release compounds which can also migrate upwards through the battery case, into the electrolyte. It is these compounds which contaminate and degrade the electrolyte, and eventually contaminate the lead plates in the battery. He says this is a long, slow process and will not be great enough to damage a battery during a storage period a few weeks or less. Storage periods of a couple of months, while not destroying the battery, will none the less degrade the battery's power output somewhat, and can shorten it's lifespan. Long storage periods, even if the battery is kept charged, will eventually lead to premature failure.
Answer 3Not anymore. Used to be true when battery cases were made from hard rubber, as they were somewhat porous and had a high-carbon content. An electrical current could be conducted through it when placed on a concrete floor, causing a weak short circuit.But today's batteries cases are ABS plastic and can sit on concrete indefinitely.
Batteries discharge slowly all the time. . . so regardless of where you leave one, if it sits long enough without being recharged, it will go dead.
Batteries are shipped in trucks and stored on shelves made of steel. So if it was a conductivity issue, all new batteries would be ruined.
Where is the alternator to a 2004 Audi A6?
it's on the bottom left side of the engine as you sit in front of the car.as you look between the engine and the radiator you'll see it.

How do you replace the alternator on a 1995 Nissan Maxima?
When my alternator went on my 95 Maxima GXE, the signs were some dash board lights came on...brake, washer fluid, etc., but apparently it is different for different cars. Luckily, I was able to drive for about 3 hrs on the battery alone. The alternator on this vehicle is EXPENSIVE, but I phoned around and eventually found a rebuilt(yellow pages under ELECTRIC MOTORS), 1 yr warranty for $150 cdn. Not bad when everyone else wanted $225 and up. Out of curiosity, I asked the guy if he would install and he said "sure, $75". Considering how old my car was and the fact that seized up bolts were a really possibility, I let him do it (took him 1-1/2hr...probably would have taken me 5 hrs). So for $225 cdn and 2 hrs later, I was back on the road. (dealer had quoted me $500 and other garages wanted $350). ...
Need to do this from underneath the right side of the car. You will have to unbolt the A/C compressor and move it our of the way. You do not have to disconnect any coolant lines to do this. Takes a while, but you can disconnect the wiring connections and bolts to the alternator. It is heavy and you will be in an awkward position, but take your time. Replacement is reverse of the above.
Using a volt meter, check the voltage while the vehicle is not running. If the voltage is below 11 or so, the battery is either not fully charged or is incapable of holding a charge. Jump start the vehicle, (make certain that you do not cross connect the battery. ALWAYS RED TO POSITIVE, BOTH VEHICLES!) and after the vehicle is running, remove the jumper cables and put the meter across the battery again. If you are maintaining anything around 13.5 V, the alternator is probably ok. More complete tests are available at some of the auto parts stores around. Out here it's Auto Zone, Checker Auto or Kragen Auto. If the alternator is holding the voltage at about 13.5 V, run the car for about 15 minutes. Shut it off, let the car sit for a couple minutes then check the battery voltage again. It should not be below 12 V. There is also a possibility that you just have dirty battery terminals. Sometimes the terminals will corrode from the battery acid. To check the terminals, put a volt meter lead on the battery post and another right next to it on the associated terminal, then have someone attempt to start the car. If the voltage is anything other than zero you have a bad connection between the battery terminal and the post. Just take it apart using a battery terminal puller, then thoroughly clean the battery post and terminal using a special brush designed for that use.
AnswerHere's an easier way to tell if it's the alternator or battery. Get a jump and then disconnect the positive side battery cable. If the car continues to run it's more than likely the battery because the battery is mainly used to start the car. The alternator provides all the power to run everything in the car and the car won't stop until you turn it off. It is best to have it checked to be sure. Most parts stores like Autozone, Advance Auto will check it for free.Can you swap solid rotors for vented rotors on an 86 Volvo 240 DL?
NO!!!.....not unless you changed for old style calipers too.....why would you want to do it?....you would be seriously reducing braking power and safety.....it's not safe or cheap or or clever way to go!!
What size alternator do you need with a 1000watt inverter with a 1999 ford e-150 4.2 liter?
A quality 1000 watt Inverter could be expected to require about 84 amps at 12V. If we figure that the charging system is going to be operating at about 13.8V this figure could drop to about 75 amps (considering conversion inefficiencies). If we then consider that the truck electrical system will require some current just to keep the truck running, say 25 amps, then we'll need an electrical budget of at least 100 amps. So if you plan to use your inverter for a continuous application then you'll need a 100 amp alternator otherwise you'll slowly discharge your battery. If for example you had a smaller 75 amp alternator then you would be draining the difference (25 amps in this case), from your battery. Since most quality automotive starting batteries have an RC (Reserve Capacity), of less than 120 minutes at a 25 amp draw you'd drain your battery in less than 2 hours. Keep in mind that nearly all alternators do not provide full rated amperage at idle. A 100 amp alternator is likely to be pumping out only 75 amps at idle. For a continuous use inverter application I'd play it safe and install at least a 120 amp alternator minimum.
What size wire for fusible link in alternator charging circuit?
2 wire nsizes smaller than the wire you are protecting.
Where is the alternator on a 98 Saturn SC2?
under the power steering pump
on the passenger side near the fire wall (back of engine)
to get it out you will need to get under the car there is a long bold and a short bolt and remember to take the serpentine belt off first!!!
also the connector might be hard to get at but after its un bolted gently pry it up with a screwdriver and pop it out

How do you repair an alternator on 98 Mercury Mystique?
1. Put the front of the car on jackstands and dis-connect the negative battery cable.
2. Remove passenger side wheel and lower splash guards. Using low profile 3/8" socket wrench or breaker bar, remove the serpentine belt from the alternator pulley.
3. Dis-connect the passenger side tie rod from the knuckle.
4. remove the driver side wheel.
5. Get 3 or 4 feet of extensions for your 3/8 socket wrench and feed them through the driver side wheel well to the upper bolt of the alternator. Yo may need to secure the socket & extensions on the bolt from up top then get back down to the driver wheel well, but it's worth the few seconds. Remove the upper bolt.
6. From below the car, loosen the lower bolt, but do not remove.
7. There is a small bracket on the alternator between mounting bolts. Remove the 10mm bolt that secures the bracket to the block.
8. From above, pry the upper tab from the mounting bracket.
9. Below the car, hold the alternator while removing the lower bolt.
10. Dis-connect the electrical to the Alternator.
11. Maneuver the alternator out through the passenger side wheel well. Takes a little thinking, but it'll come out.
12. Transfer the small bracket to the new alternator.
13. Feed the alternator in through the passenger side and make electrical connections.
14. Secure the lower alternator tab and hand tighten the lower bolt.
15. Pivot the alternator up. The upper tab may not easily fit into place. Tighten the 10mm bolt in the center bracket to the block. This will press the upper tab into place.
16. Install the upper bolt and hand tighten. Fully tighten the lower bolt now.
17. Use extensions from the driver wheel well to tighten the upper bolt.

How do you replace the alternator on a 1996 Chevy S-10 2.2L?
Safety 1st. Engage parking brake and brace wheels. Disconnect the Neg. battery terminal. Label and disconnect the wires to alternator. From below and using the tire tool that came with the truck, release the belt tensioner by inserting the tool into the "slotted" opening and rotating ccw (counter-clock wise). Loosen and remove the alternator hold down bolts. Installation is in reverse order. Note: Partial information from Haynes Repair Manual, Chevrolet S-10 & GMC Sonoma, Haynes Publishing Group, #24071.
: : I just had to do this...not the toughest job I've ever tackled. : Start by removing the fan shroud (I didn't & it just made the task more difficult). Once the shroud is out of the way you'll have much more room to release the tensioner, using a 3/8" rachet, and removing the belt. Remove the top (13mm) bolt on the back (toward the fire wall), then remove the lower (10mm) bolt on the back. Then, while supporting the alternator, remove the front 10mm bolt. Rest the alternator on a frame member to remove the electrical leads...one snaps in and the other requires a 13mm socket. : Sidebar...1/4" rachet drives or "stubby" drives are helpful! : Installation really is the reverse of this! Connect the leads, put the front bolt then the back bolts in, and replace the belt! : Good Luck!!
How do you replace the shocks on a 2001 Lincoln Town Car?
you do mean shocks and not airbags right? well, you change shocks on the rear just like any other car with them but on a Lincoln the best way is to have the car resting all the way down,"with the airbag switch off". place a jack directly on the rearend and raise the vehical a little to release tension off the bolts. it's easier to put them on this way cause when you buy new shocks they are already compressed and its hard to pull or extend a compressed shock.
