I have been doing some research and am thinking it is possible the alternator bearings have had it in my V35. That being the case, from what I understand you have to replace the whole alternator as you can't just replace the bearings.

Does anyone know what a new alternator costs for one of these cars? Mine is a 250GT sedan if that makes a difference.

Thanks

Just a guess but maybe you should look at the 350z alternator. Just guessing

I've been trying to track down the exact location of the noise and from looking at engine schematics, I've narrowed it down to that area (at least I think, I'm no car mechanic :P ). It doesn't sound like just a belt type noise to me, it sounds like a shot bearing, it's a similar noise to what I used to encounter when working as a technician on tenpin bowling pinsetting machines and 9/10 times the bearing/bushing was shot. The drive belts went on my Fiance's car a little while ago and it was a very different sound to what mine is making.

The battery is holding charge fine, so I think the alternator is still working, but I think the bearing is on the way out.

Of course I could be totally wrong too.

Whilst engine is running, use a plastic handled screwdriver on the bit you think is noisy, put ear to handle and listen... do not put head, hands or screwdriver in spinning engine bits!!

Stop engine, disconnect belt and spin alternator by hand, does it feel right? Is there any play in the bearing or end float in the shaft, is there any tight spots, does it make noise and does it feel smooth.

Then check that belt has no cracks in it, bend it backwards and look for shiny spots too...

Re-install belt and tension correctly, if a belt is not tensioned correctly bearing type noises can occur.

Start car and spray belt with a spray that is designed for reducing noise in v or spline belts. Available in all Auto shops and isn't expensive and last for ages, do not use much.

If the noise is still there and whilst the car is running, use a multimeter to make sure the voltage is correct at the battery terminals (13+ volts - 13.8-14.4v is best). Sometimes a bush inside alternator will make noise and this sometimes effects charging. Doubtful though.

As for cost, Nissan wanted $1400 for an Alternator and $300 for the regulator at Trade prices for my R33 GTS-T.

Thanks Stephen. Don't know if I am game to pull that much apart, don't know enough about the engine set up to be honest and would hate to break something. I'm putting it in to the garage tomorrow to get checked over, so hopefully they will be able to come up with the solution. Thanks for your detailed help though, really appreciated :)

Nissan sure know how to charge for parts.. well I am hoping it is not the alternator!

Hi people....while we're on alt's, may I ask the following....

Has anyone had issue (V35) with back-leak of voltage with their alt?

I've gone through 2 batteries now, and the car won't hold a charge for more than 2 days...old Batt wouldn't come back to life, my new one is dying every other day.

I placed a multi-meter in series (current test mode) to the battery, and found it was drawing well over 300mA, with everything off, (including the boot light..lol!).

I know my on board GPS draws a little current, but very little, as I tested it.

I've had this issue since I've been off work (hospital, and resting up, hence little driving), and since I had my alarm/immob installed...it could well be that!....but until I go back to the installer I'll just be looking for your thoughts on V35 alt reliability or any issues you may have heard with busted diodes in the alt rectifier pack, with this model specifically?

Charge is good, with over 14V being supplied to the batt on idle.....batt recharges very well and very quickly.....after I jump start her!..LOL!

I thankyou for any thoughts you may have.

Must have a draw somewhere... broken relay?

If you have 14v when car is running then all should be good.

Do you ever see the battery light on the dash?

Just make sure that it doesn't drop every so often... mine when down to 1 volt for a second or so, then it did it for longer and longer over a few months.

Had to change Regulator/Rectifer.

So you leave GPS on?

hey. thanx 4 the response.

No batt light on dash, ever.

I running one of those finnicky Calcium Plate Batts at the moment....I'm pulling it out and putting the old style back int there, today.

But that won't solve the current leak issue.....so...I'll be disconnecting the batt when the car is not in use, until I get back to Tower Audio, and see what they have to say.

I really hope it's not the Rec/Diode pack...it's under warranty, but the hassle is a hassle!

Do you / anyone here know the approx C draw on a dodgey alt pack..just ball park....would it be around 300mA, or a lot less/more?

Yes, my GPS is part of the entertainment system, hardwired into the car's elec's like any other radio.....but it only consumes enough power to keep the 'tracking' data/ sat-signal lock refreshed....ummm....apparently.

Cheers people and to you ST.

300ma doesn't sound a lot, but if that is what you measured it surely wouldn't flatten a battery in 2 days... must be something else you are missing.

300ma vs 450CCA battery (approx) take a while to kill the starting function I would have thought.

Would have thought that any Auto Electrician could find the current draw somewhere.

    • My take on gg2 48mm, 54mm, 58mm, and 62mm compressor map for same size compressor vs gg1 : All gg2 only outflow gg1 above 20 psi. As all g gen 2 surge line at lower left of comp map move to the right, all gg2 sacrifice spool vs same size gg1, surge line move to the right worst for 54mm gg2. So for same size compressor if you want best response, use gg1, if you want max hp at >20psi use gg2 but you will be laggier vs same size gg1. Max compressor efficiency drops to max 75% on all gg2 vs max 76%-80% of same size gg1. Iirc lower efficiency means hotter iat less dense air so lower hp at same operating point of comp map. Also curious why gg2 is mapped to lower max rpm vs same size gg1 (only 48mm size both gg1 gg2 mapped to same rpm) : 54mm gg1 165,000 rpm  vs  gg2 160,000 rpm. 58mm gg1 150,000 rpm vs gg2 140,000rpm. 62mm gg1 145,000 rpm vs gg2 140,000 rpm. If gg2 can safely spin to gg1 rpm then they can flow a bit more than as mapped. Good thing that all gg 2 interchange compressor and turbine housings with same size gg 1. So gg1 owners can buy gg2 chra only if planning to boost >20psi.
    • My stuff is all with Shannon's, granted, I don't really have imports I'm driving on the road, however, I've had multiple cars at the same time with them. Presently we have the Landcruiser on laid up cover, Sarah's Kluger on full cover, and the house insured. About 18 months ago Sarah wrote her Subaru Liberty GTB off, insured with Shannon's, and the payout, and buy back of the wreck was super quick. In 2020 we had the VF Commodore totalled in a major hailstorm. Storm was on the Saturday, I called on the Sunday and lodged it, vehicle was towed on Tuesday night, assessment team called on Wednesday to say it was a total loss and get payout details, money was in the bank on Thursday morning. Have had a few other claims both at fault, and not at fault, over the years, and never had an issue with them.   Funnily enough, they're also the cheapest insurer I find for things like Sarah's Kluger.   I will say I'm less impressed dealing with them lately around "the experience", as a lot of their staff that you deal with aren't car enthusiasts. Shannon's has a much more main stream feel ever since they decided to become "big corporate", laid a heap of staff off, and then hired a bunch of non enthusiasts. At the same time they've been making a push to be less "call us and we'll personally have someone who cares help" to "hey, this computer can do stuff for you" and are trying to get more square pegs to fit round holes. (That's just the vibe I get from them). Again, have had no issues with claims with them, but get a bit of a "less personal" feel from them.
    • A thing I wasn’t happy with with enthusiast was during the initial phone call they told me they’d insure it for 130k but needed photos.   I then sent them photos and they told me $80k as there were other cars either similar modifications available for around that price, I told them to send me the links to said cars so that I can buy them. i then sent the modification list with prices of the parts (no labor) and the price then came to 115k, which is still shy of the 130 that was agreed in the initial phone call 
    • Ask me a bit later this week before payday
    • I agree that delayed payment probably isn't the most suitable solution. It seems a solid complete transaction would be best. As I wouldn't be using this sale as a line of credit that would typically earn interest, we can probably arrange a much cleaner single transaction deal. I can do $92.52 today. Would you prefer EFT, or Cash on Pickup?  😛
