it'll just be brushes. Bought some for about $20 ready to fit in my honda, no soldering. Talking alternators & their issues, on one of my other two [same cars] one has the oil light on & other has oil & battery light on [on dash]. If i swap alts over car to car the opposite happens [still with me?]. Both charge & don't have an oiling problem, don't discharge when stopped etc. Been going on for years but just ignore it but will bring check engine light on sometimes but flick ign off & on & fixes it without stopping as engine light limits the rpm, probably good way to stop the kids thrashing it lol.

marte-mat pretty well covered it off for you but. What is the year /make/model of your car? What you describe based totally on your info points to worn out brushes but without seeing it who can be sure?

What difference is there between a petrol and diesel alternator?

diesel alternator often also contain a relative vacuum pump. then a prius has no alternator it uses the high voltage battery to convert a charge via dc to dc converter to charge the 12 volt auxillary battery. then there is smart alternators ford nissan bmw mid 2000 use them then there is free wheeling pulleys on altornators . the differences are emense if you dont know what car make model year its like asking if anyone has a cristal ball for a answer.

only nz new as it uses a Bosch alt they brushes are contained within the regulator assy screwed onto back brushes are solder in. Also important to.note on this alternator is if brushes are worn slip ring needs to.be machined or replaced and machined otherwise brushes will break their leads or it will be worn through past it's serviceable limit. Brushes are not "clipped in" also as the regulator is such a weak.point you never just replace the brushes unless you want unreliable

most newer diesels run a separate vacuums pump these days so there may be no.difference apart from fitment
I think this is the right set brushes for this alternator. Seen for $20 on aliexpress.

Do not remove battery lead while running. Check to make sure the big wire has power if it does remove and fix alternator

Some cars won't run without the battery connected even if the alternator is fine. If you get a loose battery terminal the car will then keep cutting out by itself. And yes some cars if you disconnect the battery the alternator will definitely put out way too much voltage and fry all the computers and the stereo.

My battery light came on a few days ago while driving. Then next time I started the car up it turned off once the engine was going. Same the next day, then after several hours when i started the car it came on and stayed on. It did that for several days. Now it just stays on when the cars going. The batterys goes flat and is charged by a battery charger now. The light is not on when the cars turned off, only when its running.
Would it be brushes or the diode pack? Thanks.

Worn out is worn out .bearings the lot .It is more convenient to buy a new alternator.They are not as expensive as they use to be. assume for a petrol car? Also Check the belt is not slipping

Reality is at this stage it doesn't matter what is wrong inside the alternator if it's at fault. What matters is making sure you get a accurate diagnosis making sure it's the alternator. Once that is assumed removal teardown and pricing up your options repair vs replacement. We don't know the car type so making assumptions like above could be costly

Al those parts you list a testable once off the vehicle stripped down and on the bench. No one can tell you what part is faulty on the internet while it's still on the car. Nor can they give you a price without knowing tupe of car or even more specific the number On the alt

More than likely its just the brushes, on many of the modern cars,you can replace the brushes without removing the alternator ,the brushes kind of clip onto the side of the alternator.

recon the alt is about half the price, in most cases just needs new regulator

the problem is what car if its a toyota prius then it has no alternator it uses a dcd to dc converter. You really always should state what year make model and what engine . the colour usually dont matters thats just a joke about the colour for people who have not realised that part.
