Share on social networks:
If you're using no-name or store-brand alternators from auto parts stores, those are hit or miss. You can get DENSO, Bosch, or Hitachi alternators instead of OEM (one of those companies makes the OEM anyway) too.
Cons: hit or miss
When I had a 98' Maxima and the alternator went out, I bought a remanufactured Hitachi on eBay and that one worked just fine for many years.
Pros: worked fine for years
Vehicle:
Nissan Maxima
In my case my accessories battery is being starved of charge, I have changed the alternator, j367, and both batteries. The alternator delivers 14.9 volts to the starter battery, but only 13.1volts to the AGM bat, I keep getting 'switching off consumer electrics......'
Pros: 14.9 volts to starter
Cons: 13.1volts to AGM
I ordered an alternator with code 07C903021N (Hitachi LR1190-907E) and I hope it is the right one, because there are many versions and the all look the same, except for the position of the B+ post and the DFM terminal connector with respect to the orientation of the cooling tubes.
Pros: ordered new alternator
Cons: many versions look same
Vehicle:
Volkswagen Phaeton
Part number: 07C903021N
My alternator is neither a Bosch or a Reman. It was bought new and its Hitachi in brand. Came with lifetime warranty.
Pros: lifetime warranty
Vehicle:
Volkswagen Jetta
