VZ Alternator Change

[bigdaddycool]

Anyone done a VZ alternator change before?

I got my stock 100amp one, switching to a VE 120 amp model (aparently fits vz's fine etc)....

Is it fairly easy, looks it....... my main question is here is reguarding the belts...... do I have to undo the tensioner and does it matter if the belts move (as in wont effect timing etc) ........

I beleive timing is all computer run but I'm just making sure....... *better to be safe then sorry*

[impulsesv6]

dont you tune your own car... But ask if the rubber belt that can slip will effect timing... Even in an engine that has a timing chain...

I think your better off not installing the alternator but put a solar panel on the parcel shelf... Imagine the power gain by no drag of the alternator... + you car will keep the charge overnight as you have the solar panel working...

hahahahaha Along with those painted engine covers im sure his Alloytec will be well over 300Kw when he is done.

LMAO... This is another gold thread by bigdaddyfool.

How can somebody who claims to know so much about cars, know absolutely NOTHING about how it works.

[bigdaddycool]

right..... well thanks for not answering my question. My question reguarding the alternator is cause my dads vz, an auto electricial took his off at some stage of the rebuild and dad said he clamped the belt to the pullies so they didn't move.

So I just wanted to make sure.... As for the solar panel, my battery went flat overnight one night randomly......... as far as i've found it was just an odd event where the commodore left something on randomly..... so yes I would like to make use of an autocharge system to prevent it in future if it ever happens again. Makes it hard getting to work when the car wont start obviously.

But thats ok. I'll just go ahead and do it myself while you guys flounder around acting like twits. So much for 'help' in the forum.

mate i havent been on here long. but if you dont act like a wank ppl seem to be very helpful

[PaulSV6]

Lol, but seriously

To the OP, havent done one myself, mate.
You do have to undo the tensioner to remove the alternator. Move the alternator back, then remove the belt from the pully & attach it to something so it wont move.
It does take alot of effort to move the belt when there on the pulleys. I wouldnt worry to much.

You dont get it do you? No solar panel is going to charge your battery over night!!!! hahahahahahahahaha!

[Torquative]

I think the timing is done by chains thats concealed anyway

Im pretty sure its only the aux drive belt your moving out of the way so it wont matter.

I'm pretty sure solar panels store energy from the sun, and then releases it when it requires it, anytime.
IF the vehicles is garaged at all times though, then yes, it wouldnt work.

just to put a dampner on this aswell,

the ve alternator WILL NOT work on a vz, the ve alternator dosnt not have a regulator in it as such, it is regulated in the ecm, not self governed, it will bolt up, but wont work

oh well bigfaddytool whatever ur up to hope it works out for ya.

Are you being serious?

Are you dead sure on this? ....... they look the same, both alternators I thought had the regulators built in.....

I'll now have to enquire with holden.

[the_trademarc]

Well, the solar panels we have at our house does that, so when you turn the lights on for instance, the first source of energy is from the panels, and once that's been exhausted it switches to electricity.
So I'm only assuming, theoretically, it would be the same for a car too.

[Torquative]

I'll be surprised if Holden even know, the answer your more then likely going to get it "the part number is different for VE and VZ so no it wont work"

Theres alot Holden aftersales dont know about their product.

Wish I could get away with not knowing much about the products I deal with but thems the breaks.

[bigdaddycool]

Holden are such a waste of time.........

It's a Mitsubishi Electric OEM number AOO3TG1491.

From what i've managed to find out it's the other way around, the VZ's dont have regulators and talk to the computer, the VE's have a regulator.

I dunno, I've been assured it will work. So I'll put it in and find out.

[PaulSV6]

Just because they look the same doesnt mean the VE alternator will work in the VZ.

As said in the previous post, these to alternators will have different part numbers & therefore Holden will say it wont work.

Why dont u just get a VZ 120amp alternator!

[bigdaddycool]

It's a VZ/VE 120amp alternator........ I've already got it and it's sitting at home. so it should be fine, the point was to get a 120amp...... so i take it the alternators on ve's are just 120amp vz police packs?.......

i dunno, i'll see how it goes when i put it in.

There are heaps of places advertising the same alternator. VZ to VE V6 etc

[Torquative]

oh well give it a shot and let us know what happens I guess

[andyman]

well ive got the holden document sitting here daying it wont work, thats enough for me, but by all mean go on and try it,

is the plug for signal wires even the same?


sitting here awaiting results with a couple cans of rum here....

no its the way i said, which you think is the other way round but isnt, its completly the opposite.... get it?


the rvm system is the reason why ve's had initally flat battery problems, cause the ecm was allowing the alternator to pump enough juice out, its also why the ve's have an ammeter built onto the earth lead, and vz's dont

[andyman]

also you do realise that the alternator DOES NOT continuasly output 120amp, if it did it would fry your battery everytime the car was running,

a normal vz, with no light on, just stocko stereo etc and a decent battery they alt will only put out about 40amp max while running


im still running 100amp alt, i have a full alpine stereo, dual battery setup that powers my fridge, and shortly when my trailer is on the road, it will have a deep cycle battery up to a dual battery isolator hooked upto the car too,

ive tested it and with what i mentioned without the trailer, but with car lights on i couldnt get it over 70-80amp output

Andy, I think you are wasting your breath mate (or keystrokes in this case). Let him go..

i know but i like having the last word haha <<<^^^ cah ching haha

[Torquative]

Hey Andy,

on that score my car was an EX NSW Police unmarked car as your aware, and it still has some battle scars to proove it. It was kitted out with everything from high intensity LED dash and parcel shelf mounted strobe lights, the usual Police digital radio which is left ON 24/7, 25 watt UHF radio, onboard MDT data terminal (on board computer) plus all the other bits and pieces cop cars are fitted with these days to survive in the regional areas of NSW ... and as you've pointed out its only running a 100 amp alternator too.

Also Holdens has regulators since the early days, my '76 HJ and my mates 1972 HQ have alternators with regulators, why would Holden go to ECM technology for the VZ then take a step back for the car that has "all the technology" in it?

Anyhoo like everyone I wait on the results, and I raise your rum by holding a bourbon in hand
