alternator wiring

[tara]

hi,
i was ready to install my new alternator when i noticed that the back of it was different from the old one, so just to make sure how to wire correctly it if some one can help, i would one more time much appreciate
thanks
Tara

on the old alternator there is only one pin plug for the green wire but there are 2 on the new one, which one is the good one ?


on the new one there a black washer on one of the two bolts, so which one of the two thiner wires should put on this one ?

it looks very similar to my new alternator

Looks like one or the other of these alternators is the wrong part for your application.

The new alternator mates to a plug that fits over both of the terminals.

I would trace out the wiring for my alternator and regulator on a sheet of paper, and then compare that with the wiring and discussion in the factory service manual. I don't know which one of these alternators is right for your Jeep, but you could compare it to the pictures in the manual to see.

i bought the new from rockauto and lookks little different from the old which is the original model. does it mean that i won't work ???
i guess the sames wires should be plug at different locations, no ?

No. If the wiring was never modified, and you have the right part, the replacement should have the identical number and type of connections. Those are not the same part. Look at them. They are very different.

it seems that AMC was using the same model as my new alternator on its V8 engine, may be jeep has used another model but they should work the same if wired correctly

this is what i have ordered from rockauto

and you are from the picture this exactly the same than my old one.

Then they sent you the wrong part. You need the part shown in the picture, that matches what you have.

as you can see the number of this delco remy part is 20170, and that s what is print on the box.

anyway just one idea : both have exactlt same shape so the new odd one will fit at the location of the original one. they both have 4 wires :
regulator aux, ground and field, and one thicker to the battery. why this alternator couldn't work ?

i m saying that cos it is too expensive to ship it back to USA and i m not sure rockauto would refund my money cos i bought 3 months ago.

If you want to go that way, you will need to figure out what application it fits. Then you can identify each terminal, and wire it up like that application. You can probably make your existing regulator work; if not, you will need a regulator that matches the new alternator.

I would contact RockAuto anyway ... if they sent you the wrong part, they should pay for return shipping. If you do not want to contact Rock Auto, perhaps you can contact Remy directly. The alternator is still under warranty, even though it has been 3 mo since purchase.

[tgreese]

Oh.

Look at this -



The extra terminal is a ground. I did not see that because of the shadow in your photo. You don't need it. That alternator should work ok.

all good, thank you Tim

hello, i have a question : i used my voltmeter and notice that i got 6,5 v at the field connection at about 3500 rpm and 13.5 v at the AUX (or stator) connection.
what should i connect to the AUX connection ?

thanks
