[Help] What to do with an old alternator

I just had my alternator replaced and I asked my mechanic if he could take my old one to recycle. He said yes, but he ended up giving me back my old one (Which I don't mind at least they are honest).

But now, what do I do with it? I bought it off ebay and not at a parts store, so I know I will not get a core charge at all.

Should I look for a shop that specializes in remanufacturing alternators or do I have other options?

The metal inside is worth some money (copper wiring).

Hmm, I just replaced my alternator a little while ago, and it had a $30 or $40 core value, so I'm not sure why he ended up giving you back the old alternator.

Unless there's damage to the housing or wiring (methinks that's not very likely) they are rebuildable with not much effort, so they worth quite a bit.
But their scrap value is probably not much.

Parts stores used to charge a core charge on alternators.

Since they now seem to be rebuilt in China, seems they don't want the old to ship back.

FWIW I recently bought a working Toyota alternator at a wrecker for $15. I don't see much value or use in your defective alternator.
Housing is probably aluminum, windings are (dirty) copper. If you spend the time to pull it apart you may get near $5 at the local scrap metal dealer.
I give stuff like this to a local guy who makes a meager living recycling metals.

If you were not charged a core value by the seller on ebay then look for a local recycler or rebuilder that purchases cores.

I decided to take it to a scrap yard. Got $2.75 for the lot. Better than nothing I suppose.

Would you do it again ? For $2.75, I suspect not....

I knew I wouldn't get much for it from scrapping, so it's okay...I even offered it to a mechanic friend of mine to see if he could rebuild it, but he said nope, so off to the scrap heap.

If he was bored and enjoys rebuilding them, he realizes he then has to sit on it and wait for someone to need that particular part... I suspect that years ago, you'd remove your own dead alternator, rebuilt it, and put it back on the car.

I have rebuilt dozens, mostly back in the '70-80s. You used to be able to get parts, even the individual diodes easily.

Now, just the regulator is replaceable (one of the most common failures.) Have seen many fouled by oil that carbons up the armature.

GM and Ford alts often had a screw you can ground to test if the alternator itself is good (will charge at max current when screw is grounded.)

I'd still rebuild them and do sometimes. I have seen many people go through 2-3 "rebuilt" alternators. There is no quality control, one of the last ones I replaced, all the internal screws had fallen out.
