Reviews of TYC alternator

I bought the TYC one for my cobra and it was a good one. Better than the reman you could get at a local parts store.

I got a TYC off Rockauto and it’s kind of annoying that it will sometimes drop in and out of charge at idle ever since I replaced it but other than that it has been working for a year and 26,500 miles so far. It had way less copper winding material and was lighter weight than the stock unit which the oem is clearly superior.

I got a brand new TYC-brand one from Amazon, still strong 5 years later. No complaints.

I've got this bosch OEM alternator i pulled off my car a while back. Because, well; it looked like a fire hazard after years of oil accumulation. Replaced it with a TYC Alternator from Rock Auto that throws a whole bunch of codes.

I've had TYC before. They're not bad

I am running a 130 amp TYC alternator from a Nissan Titan. It's 100% bolt in. It's cheaper than the 110 amp stock one too, just over $100 on Amazon IIRC. I have used TYC alternators 3 times, never had any issues.

Do NOT buy TYC brand alternators. They may be good for headlights and other parts, but I have gone through 2 NEW TYC alternators within the span of 6 months. I do redline my car every so often, however these should be built to handle such loads. Even though TYC was good with their warrantee to replace it, I still had to deal with all the shipping costs and labor to install the parts. not worth it. Ended up going with Denso remanufactured instead.

Bought new alternator TYC from rockauto. with a volt meter, I checked for voltage at the alternator B+. it charges at 14.2 when reved to 3000 rpm then it gets to idle, it remains at 14.2.
