Car has started making epic squealing noises, and after an initial panic that it was turbo related, it looks like it's now alternator. Hopefully that proves right when I pull the belt off and check, but some basic tests show that it's most likely, and probably explains some battery deaths and other electrical issues.

I couldn't find a part number on here - surely someone has replaced an alternator on an M35? Anyone rebuilt one? Seems like bearings so we're tossing up rebuilding it and replacing the bearings depending on costs etc.

Everything in an alternator search seems to be RB... no VQ love.

Surely Scott isn't the only one that knows.

If 350Z belts are the same as NM35 belts, I guess that means the alternator is probably the same (well, it looks like the VQ35HRs had a different alternator to the VQ35DEs, bu you get my point).

Looks like 350Z units are available out of the US for $150-200, or high amp versions for $200+.

lol ok. He should have a couple.

Part number for VQ25DD and VQ35DE is 23100-CD010, Amayama have them for $507. Surely a VQ25DET would be the same as those two?

Fortunately it looks like its a standard Mitsubishi part, so bearings are available, part number 2312030R10 and 231200V017, Amayama flog them off for $25 or less per bearing (they want FIVE HUNDRED DORRAH for a complete alternator!).

I have one here if you need it mate, otherwise rip it apart and check the bearing numbers, they should be available at the local bearing supplier...

I would be cleaning up the slip rings on a lathe and replacing the brushes if you can find them.

Cheers mate. Dad's got a lathe so that should be fine. Not sure about brushes, might have to get a sparky to do that bit.

Sounds like there are a few 350Z owners in the states putting higher amperage units in for stereos etc. Not sure if that's worth doing at the same time, but seems like pulling it apart is going to be cheapest, easiest and quickest.

Cheers Cam. First things first I'll rip it off and see if I can rebuild it with new bearings.

Funny thing is P/N 23100-AM610 can be found online from a bunch of places. Only two hits for 23100-AL31A, one being this page.

If it's the same as the V35 and Pathfinder, why wouldn't it be the same as 350Z different p/n, so must be different, maybe higher amperage?

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
