I have a 2012 Odyssey that seems to be eating Alternators. The original OEM Alternator went out at about 60k miles. I replaced with an Oreilly's re-manufactured ULTIMA Alternator. Replacing is a BEAR. The replacement went bad about a year and a half later at around 80K miles. The re-replacement is now testing bad after about 2 weeks. Thats now 3 dead alternators in less than 100K miles.
Has anyone heard of a problem that would cause an Odyssey to destroy alternators? I have not replaced 3 alternators on all the cars I have ever owned, much less one with under a 100K miles. Could be the Ultima alternators are just garbage but I want to be sure there is not some other reason. Shop is telling me the Alternator is testing bad but Maybe something is killing them.

Battery is good.

Symptom.... battery and other dash lights come on and "check charging system" flashes. Car drives but will eventually die on the side of the road wtih no power windows, AC, radio and with a drained battery. Battery is known good ( I pulled it out of a working car to get it to the shop).

 

STOP BUYING CHEAP REMAN PARTS! Replace with a new quality piece and your troubles will cease! You are probably losing the internal regulator or some windings. Typical reman, only fix what is broken and not truly remanufactured.

Yes, I am replacing with an OEM Alternator this time. Its $624 to replace so I just don't want to replace a new OEM part into a system that has a problem that is blowing the Alternator. I am not fighting that bear again with its 1/4 inch of room to get the part in. Hopefully a quality alternator fixes it. By "Quality" I mean I hope it lasts more than the 60K miles the first OEM part lasted.

 

Double check the resistance between the charging terminal and the fuse box for any damage to the charging wire. If you see any corrosion or really dark copper strands, you may want to run a new charging wire at the same time you install that new, high-dollar OEM alternator.
