New alternator arrived today:



For the extra $10, I got the B15/P11 version rated at 160 amps vs 150 amps. All the plugs look right to me:



I will let you know about fitment after install on Wednesday. BTW, if there are no fitment issues, this would also work in any B13 or B14 as well.

Couple of questions...

1. is the factory wiring even up to being able to pass that kind of peak amperage?? (not that its likely to be pushing that all the time, but still...)

2. how small is the pully compared to stock (or is it the same diameter)

3. is the amperage listed an absolute peak at a stupidly high rpm or can it produce that amperage from a particular rpm (as the factory ones are rated to produce a minimum of X amps at Y rpm and produce the peak at ~3000rpm or something similar)

More out of interest than anything, if it fits and works i guess really that's all that matters.

What I was thinking..

I just replaced my battery and alternator with a new 80 amp and now I get a brake and battery light all the time with all the relays so hot they should be melting the plastic covers.

It's making 14.95v at idle and easily make 15.5v at 2k and I don't like this on my factory wiring. Does anyone know what a factory 92 nx2000 alternator amperage should be.

I may just have a junk new alternator with a bad voltage regulator/rectifier or its just too many amps for my car.

that does sound high, you should remove it and take it to get tested

I put the 90 amp in my nx last summer. No issues EXCEPT the annoying ass no charge and brake light. Driving me nuts. other than that no issues.

It has a regulator built in that tells the ECU whats going on. Did the wire map match up between the two?
