If you were family or my customer I would get the Bosch.
2004 Limited with 310000 miles alternator went out so went to local service shop . They were able to get it in and repaired next morning other shops in the area are a week backlog.Parts we're 310.00 (Duralast alt.and Gates belt)
IMO a rebuilt German Bosch unit is far superior to the Chinese alts.
I went with a Duralast Gold(90A) which never gave me a issue. If I had a oscilliscope im sure it had good output.
Possibly the alternator, mine did that so I bought a brand new duralast gold alternator and it solved so many of my problems.
I’ve never had an issue with a Duralast starter or alternator. However, honestly, I probably wouldn’t put one on my Lexus. I’ve generally shoved them into cheaper and simpler cars.
The alternator went out on it, and I had to replace it four times due to faulty over the counter rebuilt Bosch parts.
supplier willing to give me a Bosch remanufactured alternator (as good faith) to compare. after installation on Bosch, the result is worse than the Denso (output at alternator at 12.5V)
Don\u2019t get a Bosch
I replaced the Alternator on my 2016 Mini Cooper Paceman with a brand new Bosch Alternator. For whatever reason the Alternator is only putting out 11-11.6 volts.
