Depending on the make of your car, it is usually 4-6 very small (and very fragile!!) screws holding the two sides together. look very carefully and you will see them but be extremely careful not to strip them or even break them when disassembling or reassembling the unit
Don't do it. You will have a ball putting the alternator brushes & springs back in if you have never done this before.
open the hood and look down and to the left of top center.
You have an open connection from the large alternator output post to the starter main battery post or fuses blown or circuits open feeding the alternator control wiring.
When you open the hood and are standing in front of the Rav4 the alternator is on the left hand front side of the engine. You will see a large pulley with the alternator belt on it to the left of the alternator.
On your alternator, there should be two bolts on either side of the alternator. Losen the surentine belt up enoungh to slide off the pully of the alternator. Remove the two bolts on both sides of the alternator and slide the alternator up.
If the bearings in the alternator get bad enough it can lock up.
Possible causes,- Faulty battery- Alternator belt missing or loose- Faulty Alternator- Alternator harness is open or shorted- Alternator circuit poor electrical connection
Open the engine cover. You will see the fan belt. The thing bolted to the top pulley is the alternator, and it's sitting on the alternator stand. There's a spout coming up from the left side of the alternator stand, and it's got a screw-in cap normally with a hose coming out of it that runs up to the air filter. That spout is where the oil goes.
the work of an alternator is to charge up the battery while the vehicle is in motion
Noting, just install it and hook it up.
open the hood of the car go to the alternator. there should be a bolt facing the firewall on the alternator this adjusts it. make sure the other bolts are loose first. good luck!
There is a wire from the alternator to the starter motor. On the starter motor end, there is a fusible link that sometimes melts. With the engine off, check the battery volts and check the volts on the big red alternator wire. If they are not the same voltage, the link is open. If the link is open, the battery will not charge
wires are crossed or you have a short in the wiring from the alternator to the battery.
