Alternator OEM FORD or OEM Nissan

2021 Got the extended warranty, one year after the standard warranty went, so did my alternator. Extended warranty covered it.

Had one do this on me and it was the alternator.

Z1 Offroad has an OEM Nissan remanufactured for a good price, that's I what I went with.

Most of my experience is from the Infiniti side of the family, but I replaced an alternator on all my higher mileage vehicles. In general, the diode packs in Nissan alternators go out after about 150k miles or so.

If you don\u2019t have huge power requirements and are happy with the standard amperage then just grab an NA Z32 alternator from a wrecker and modify the tensioner bolt to suit.

12-plate Fiesta, 106k miles

- Alternator is intermittent

- Rear bushes are audibly fucked

- Radiator fan packed up so it overheats when idling in warm weather

I’ve been busting my butt all day trying to get the alternator out of my 2004 ford focus (mk1) for a few painful reasons

November of 2023 I had to replace the alternator. I purchased an aftermarket and had a mechanic friend install it for me. 6 weeks later it started acting up again and left me stranded. The battery tested good, alternator was bad. I returned the alternator and was warranted a second one. Roughly 2 months later, the battery light comes on while I am out of town. I pulled into a local parts store and had it tested. Battery tested fine. Alternator tested bad. The Nissan dealership says it is the alternator. But since I had not used a factory alternator that was the problem. Apparently the aftermarket alternators can not handle the load and are not set up properly.

I ended up replacing the alternator but it wasn\u2019t a genuine Nissan part and it didn\u2019t work.

My neighbor had a Ford mustang and he had to jump start it about once a week. I checked the alternator and it had power when the car was off. Bad diode.
