After 15 years my alternator gave out. So my question is, Do most of you go with rebuilds or new?
Mine is for a 2004 zx5 2.3l But i noticed 2 different amps 90 or 115.
This project is like no other alt. chg I've done. It'll be just a little more of challenge. but doable.

Thanks

If you plan on keeping the car for at least 5 more years - new. If you're selling or trading in that time - rebuilt.

After that day the battery light was on and did a meter test it wasn't charging. Car sat for three days started and no battery light charging at 14.4. If an alternator goes it goes all at once correct? So now maybe its just the pigtail? I haven't gone into it yet to investigate it'll be nice if its just that. Or the alternator has a poltergeist lol

Well after 1 1/2 hrs later the unit is out. The pigtail seems fine no corrosion. But should I replace anyways?
The alternator were the positive connects to is corroded I guess a new ALT. is in order.
The positive lead has a little corrosion but I can scrap it of with my finger just surface green. So what do you think?

No. You can lose one phase, still have volts but lose current making ability and not be able to keep the battery charged.

The photos do show a compelling case for a different cause, though.

*Change that terminal and at least the portion of the red cable that has oxidized. You might consider a new cable section/harness all together for it*

That cable is likely a LONG one.

Your profile says you're from Maine, so salt-on-roads-in-winter territory.

Worth spending the $75 or so for a whole new harness, IMHO. Your starter connection probably has the same corrosion, and possibly the battery end too. I was too cheap to do that and jerry-rigged a new terminal for the alternator, then ended up doing the starter one a few months later on my '07. Would have saved hours just doing it once.

Cable connects to battery +, starter, and alternator. For OPs 2004 2.3l cable is Motorcraft WC95823:

The alt post and outlet plate is dead there, an enterprising person can renew all that without spending much at all. It won't involve OEM part though, I change them up on the zetecs all day long, on those I drop the plate completely, just one less part to go bad. .
