Is an alternator for a 1993 Nissan Pathfiner interchangeable with a 1995 Nissan Pathfiner?
Yes they would be interchangeable. The body styles of cars go for ten year interval's so long as the engines are the same size it will work.
How do you take the alternator fuse off a 1993 Nissan Quest?
Under the hood, right next to the battery, there is a fusebox. There is a 15A fuse in this fuse box labeled audio.
This is the fuse that interrupts the default power signal for the stock radio.
Most aftermarket radios rely on an adapter harness that changes the stock wiring to the standard wiring making it easier to connect the replacement radio, so I would say that in about 95% of instances this is the fuse that you would check first. It is my experience that even if your aftermarket radio has a fuse directly on the rear of the headunit, you most likely blow the primary fuse first.

How do you replace the alternator on an 04 dodge ram?
Its real easy. 1st Get a breaker bar (an extremely long ratchet like a torque wrench). Locate the idler pulley and the size the bolt for a socket that holds the idler pulley on the idler arm (Hint: The idler pulley is just a pulley connected to a springloaded assembly attached to your enginge block putting pressure on the serpentine belt so it is tight around all the component pulleys (alternator, power steering, crankshaft, etc. pulleys).Using the correct size socket attached to the breaker bar for leverage put the socket onto the bolt head and pull or push the bolt head of the idler puller either forward or backward (which ever way causes the tension arm to move thus moving the idler pulley so that pressure is removed from the serpentine belt). Now remove the serpentine belt. A serpentine belt diagram should be located somewhere on a decal near the radiator or some other location under the hood...if not, before you remove the serpentine belt, map out the serpentines route with pen and paper so you can put the new one on the same exact way. When putting on the new belt you will again have to position the idler pulley usig the breaker bar and socket such that you can stretch the new belt over all the component pulleys...please note...you will only have one free hand when your doing this, so make it count and be patient...you will succeed. Good luck ...maxvolt1@verizon.net

When do you know is time to replace the alternator?
The alternator should only have to be replaced if it has either failed to provide sufficient current to keep the battery charged and the car's electrical system supplied, or it has suffered mechanical damage like a worn bearing or damaged casing. Replacement for age alone is not necessary.
Where is the fuse that is between the alternator and the battery on a 1996 Chevy Astro 4.3L?
The fuse between the battery and alternator is a fusible link in the small wire that hooks up to the battery terminal along with the regular battery cable. It looks like a thick spot in the wiring. To replace, the cable must be replaced. .
How do you change an alternator in a 1988 jeep?
To remove ours we had to go underneath and take it out that way. Once we got all the bolts out we had to take off the brackets to get it to drop out. Installation is the reverse of removal. Quite a PITA!!!
Does running the car engine recharge a drained battery?
No, you must have a charged battery for the alternator to work.
Here's an explanation of how the charging system works:

How do you replace the alternator on a 1997 Chevy Cavalier?
TAke the belt off, then the neg battery cable. Remove the wires and mounting bolts.
I would add that it's a very tight fit but you can remove the old unit and insert the new unit without having remove or relocate other parts/brackets. I did the job myself, and there were several times I almost gave up - but it can be done it just takes time to rotate and jimmy it into the position for mounting.

Everyone should have a manual for their vehicle, and the library should have a professional shop manual available, for FREE, in the reference section(make copies of the correct sections) read up and fix it like a PRO! :) good luck-Dave
How do you replace the alternator on a 1997 Chevy Malibu?
It depends on what model you have, but most are the same.
Disconnect the battery! Loosen the tensioner for the serpentine belt and pull the belt off the alternator pulley. Remove the bolt holding the alternator at the 4:00 o'clock position
Remove the nut at the right rear side of the alternator
Remove the bolt at the next to it nearer you. All bolts have 15mm heads, but you're going to need a deep well socket to get the nut off. Pull out the alternator and remove the plug from it and also remove the red wire attached to the back. You're going to need a 13mm socket and a 13mm flat wrench. Replace the alternator by reversing the steps above. Reattaching the serpentine belt is a pain.
In your PCM not the alternator
Its built in the alternator be sure that you replace the alt with the same amp. alt it could be a 90 or 124 amp alternator. Replace the belt while you have the alternator off.
How do you wire a 12 volt automotive relay?
there should be a diagram on the side of the relay with the pin numbers and some symbols. the pins that are on the coil or control side can be wired power and ground. this generally goes through a switch. the load side has a small gate looking symbol these can be wired power and ground either way and this is the side that you connect to whatever you are powering on. make sure to use a fuse on this circuit on the power lead.
Where is the alternator on a 2004 Ford Freestar?

What is the voltage of a 2001 dodge caravan alternator?
Most or all automotive alternators output 12+/- Volts DC. The actual output varies slightly depending on the age of the alternator. A new one typically outputs around 14Volts which decreases with age. Once the alternator starts ouputting less than 12Volts, you should consider rebuilding or replacing it, since it won't be able to keep up to the vehicle's electrical demands.
Alternators should be between 13-15 volts. If it only outputs 12 volts, then it is bad....an alternator cannot maintain charge on the battery (12.5 volts ideally) and provide amperage to all of the accessories on the car with only 12 volts output. More importantly, the amperage and diode pattern on your alternator determines good or bad. You cannot properly test an alternator with a multimeter.
