Alternator Got new one at junk yard but written on is 03 centtry

Did you ever think that the salvage yard part might be junk and has nothing to do with the mechanic that tried helping you out?

THE JUNK YARD ITEM MAY BE JUST AS BAD

Well if its the motor that wouldn't be the best idea you've made. Alternators are expensive brand new, but you could also go to a junk yard and extract the Alternator from a parts jeep. Motor fan does not really need to be replaced, depending on the damage or if it is creating a shaking.

Just had a similar issue with my 09 CVPI.
Charge the battery, start the car.
Car starts and is running, good.
Now disconnect the ground from the battery.
The car still runs. Battery or wire issues something is draining the battery.
Car dies. The alternator is shot.
Got to junk yard find one for your vehicle.
My "battery" light came on and I pulled both the battery and the alternator too them to be tested. Both tested good on their systems. Did the above test and changed the alternator. No issues as of yet and no "battery light. Problem solved.
Junk yard alternator $25.00, $5.00 core.
New alternator $355.xx plus tax and $15.00 core.
Core is money I will get back when I turn in the old alternator.

go to the junk yard or dealer and get a new one

bad alternator if its a so called rebuilt one they are usually hit and miss i have had better luck at the junk yard lower price and the same product

you could maybe find one of these at a junk yard (from the same model vehicle) I don't think they make any universal parts for this purpose. find out what is the Latest year model that looks the same as your 03, could be an 05 or 06 which would be the newest possible part (without buying a new one from dealer)

If your old alternator was shorted, it may have blown fuse #8 in the instrument panel fuse block. It is a 10 Amp fuse and is the ignition circuit feed for the alternator.

unless you get them from the dealer, the only other place you may have some luck is the "junk-yard"

Most junk-yards have a search feature and will search other yards automatically

there's your problem......you have a cheap alternator. Buy atleast refurbished never used once especially from a junk yard. Sounds like the pulley is worn.
