2 Bosch used Alternators

Both Alternators are Bosch one is a 120V that still runs but on my diagnostic machine two days before vacation read I had a charging issue so I ordered an alternator but took a different car because I didn’t have the time. The other alt was on vehicle 10 years ago when I bought vehicle it is a clutch pulley and is 140v the one that still works is from a junk yard 7 years ago without clutch but like I said still officially runs... you can buy two new regulators and replace and then sell them and make money. Or if you’re like me having them on hand to avoid the hassle of core charges are nice!
